Description

The object of the present invention is referred to, as its title indicates. to a rotary internal combustion engine that uses alternative fuels for its operation, of the type of engines with a certain analog to the Wankel engine, but with certain technical differences that distance it from it, such as; they do not have carburetor, switch for ignition. nor spark-producing spark plugs, in addition to other technical differences, designed for their operation to be carried out using fuels, vegetable oil and water (alternative or renewable fuels), and particularly refers to a primary procedure for dissociating hydrogen from water (elecrolytic dissociation of the water molecule), said procedure encompassing a peculiar chemical reaction, such as the hydrolysis of water with the esters of the vegetable oil, and linked to a procedure to the operation of the engine proposed. Accordingly, the present invention is in the field of the internal combustion rotary engine technique, which uses biofuels for its operation, that is, alternative or renewable fuels of petroleum-derived fossil fuels (gasoline and diesel) that are used nowadays. Presenting the aforementioned invention, important economic and environmental advantages over the currently existing internal combustion rotary engines.

Currently, different types of internal combustion rotary engines are known that use alternative fuels for their operation, and which are generally the same engines that work equally with fossil fuels derived from petroleum (gasoline), and which can also use Ethanol for their operation, also known as Bioethanol or Bioalcohol and that can work in these engines as a single fuel (if they are specifically designed for this biofuel) or by mixing it with gasoline. The engines mentioned above with the necessary conditioning can also use hydrogen as an alternative fuel.

One of the main disadvantages of the current internal combustion rotary engines that use these Biofuels, is that they are not economically profitable enough compared to those that use fossil fuels, and this is because the production of said Biofuels requires a successive series of treatments in specialized plants that are not entirely cheap, so that the final price in the market, for the consumer, is expensive. The advantage of the rotary engine of the present invention is that it can use scales or (approximate levels between 1% to 50% less fuel (from vegetable oil) in its combustion time than the rest of the current rotary molders, providing the rest of the energy necessary for competitive efficiency, the volume of water, which may be in a scale or approximate index between 1% and 50% of the mixture

which is used in conjunction with vegetable oil in the combustion thereof. And obviously, a liter of desalinated water is much cheaper than a liter of any other biofuel or fossil fuels.

Although the environmental advantages of this type of internal combustion rotary engines, which use Ethanol or Hydrogen, are important and obvious, this does not happen with the possible economic advantages for users, since both the production of Ethanol or Hydrogen is expensive, due to the different treatments to obtain them, and therefore, the cost or price of these fuels in the market, for the user, are generally higher than the prices of fossil fuels (Petrol).

It would be desirable, therefore, to have a rotary internal combustion engine, which could use another or other types of Biofuels for its operation, which were cheaper for the user, and that also respect the environment, such as using oil together water plant, object of the rotary engine that is desired to be developed in the present invention.

Vegetable oil comes from a renewable source and, contributes to improving the environment, since it prevents global warming, since the CO2 (carbon dioxide) that is generated in its combustion, will then be absorbed by the plantations that are used to produce the vegetable oil, since as we know the plants absorb CO2 to be able to carry out photosynthesis and thus develop. Therefore, we thus reach a closed cycle, where the CO2 generated by the combustion of vegetable oil is practically reduced to zero when absorbed by the plantations from which we obtain the vegetable oil, in addition due to these plantations, agriculture is helped to develop. Another important advantage of vegetable oil and water as fuels is that no new infrastructure would be needed to commercialize them, since the same gas stations and machines could be used to dispense the existing fuel in them.

The water to be used in this type of engine to be proposed, would also be economical in comparison with the Biofuels and fossil fuels currently used. The idea would be, not to use the fresh water we consume in our homes, if not, use desalinated water, collecting seas and oceans. The cost of the cubic meter of desalinated water is currently approximately 0.60 Euros, and the cubic meter could cost one Euro, due to the successive increase in the price of oil. However, even at 1 Euro per cubic meter, it is still very economical to use as fuel, since a liter of desalinated water would cost, 0.001 Euros. It would be necessary to ask, if using the water of the seas and oceans as fuel, is sustainable and if it somehow affects it to our planet, the answer is clear, it is perfectly sustainable and does not affect it to the least our planet. Since doing a few calculations we get the answer; World oil consumption can currently be in

845,910 Millions of liters per year. If used exclusively worldwide. Vegetable oil and water as fuel, and providing for the consumption of water in the engine mixture of the present invention. It can be carried out in an approximate scale between 1% to 50% (depending on the characteristics and configuration of the engine), the annual water consumption for 20% for example, would be about 169,182 Million liters. Since three-quarters of the surface of our planet is water, the thickness of the surface layer or film of water that will be consumed annually in the entire surface of the globe would be 0.00011 mm, in 1,000 years it would be consumed water layer thickness of 0.11 thousand / meters, approximately one tenth of a millimeter in Thousand years, so, as we can see, water along with vegetable oil, can be a sustainable and renewable Biocombuslible, and possible water consumption , not to affect our planet as minimal as it would be infinitely small the thickness of the layer of water, which could be consumed throughout the globe, over a long period of time. As we can assume, and after all that has been said, a rotary internal combustion engine that uses vegetable oil and water for its operation, as it is proposed in the present invention, has very important economic, technical and environmental advantages, which must be taken advantage of.

However, currently existing internal combustion rotary engines, due to their own consistency, their structure, composition of their elements, configuration and way of operation, cannot work in any way with these alternative fuels that we propose, such as using as biofuels together vegetable oil and water, in these engines.

In order to create a new rotary internal combustion engine that uses alternative fuel biofuels for its operation, cheaper than existing ones, as they are in this case, using water and vegetable oil together, the internal combustion rotary engine has been developed, object of the present invention.

A first object of the present invention relates in general to the development of new rotary molores of one more rotors, of internal combustion, which use alternative fuels for their operation, of the type of engines with some analogy to the Wankel engine, but with certain technical differences that distance it from it, such as; they do not have carburetor, ignition breaker, or spark plugs, in addition to other technical differences that will be detailed later. the aforementioned internal combustion rotary engines, may be, either shared injection in an auxiliary pre-combustion chamber and in a lobe (or spaces delimited between the faces of the rotor, the inner hollow in the form of eight lying on the stator and side walls thereof) corresponding to the time or phase of compression, or direct injection into the lobe corresponding to the time or phase of compression, when the engine does not have an auxiliary pre-combustion chamber. These differentiating qualities being, for which two embodiments are proposed by way of example in this invention, which we will describe later. But in all cases of these rotary engines, they all share some common and particular common characteristics, which are that they will use as fuel for their operation, vegetable oil and water, and also share the same procedure in their operation, logically adapted to their respective configurations These engines are suitable, so that in their operation they primarily comprise a procedure for dissociating hydrogen from water (electrolytic dissociation of the water molecule) and also encompassing a peculiar reaction of hydrolysis of water with the esters of vegetable oil. The vegetable oil to be used may be either newly manufactured or recycled once it has been filtered and solid waste has been removed.

A second object of the present invention relates to the aforementioned procedure related to the operation of the proposed rotary engine, and which will be determined with the detailed description of the development and necessary steps to be followed in the process, so that with the operation of the engine , the dissociation of hydrogen from water (electrolytic dissociation of the water molecule) can be obtained primarily with this procedure, said dissociation of hydrogen being understood as a primary or primary chemical transformation or reaction, which is encompassed and chained with a peculiar chemical reaction of hydrolysis of the water with the esters of the vegetable oil, the aforementioned practically simultaneous chemical reactions occurring, and linked to said chemical reactions and with it, the whole process itself, to the operation of the engine proposed in the present invention. This procedure is characterized in that said dissociation of hydrogen from water (electrolytic dissociation), as well as the peculiar chemical reaction of hydrolysis of water with esters of vegetable oil are practically carried out simultaneously with their combustion.

More specifically, the internal combustion rotary engine that uses alternative fuels for its operation, object of the present invention, refers in general to internal combustion engines, and in particular, according to a first embodiment of the present invention, refers to a new rotary combustion engine

internal of one or more rotors, in which part of the fuel is injected into an auxiliary pre-combustion chamber and another part thereof in the lobe corresponding to the compression phase or time, said lobe being the space that delimits one of the faces of the rotor with the internal hollow of the stator in a certain position or positions, designed so that its operation is carried out using as fuels, vegetable oil and water. Not being necessary in this new engine the carburetor, the ignition breaker, or spark plugs that produce spark. With a certain analog to the Wankel engine, it is mainly composed of; lubrication system, cooling system. peculiar electrical and combustion systems, regulators for both the air inlet and the fuel inlet, inlet for the cooling and grease oil, suction pump that collects the oil from the lubrication, an engine block or stator with its hollow interior in fonna of eight of wide waist, lying down and limited by its lateral walls of both sides, and for each transverse partition of the stator hollow, it comprises; a triangular rotor on whose faces, the surface of its indentations may be either parallel to the face of the rotor or parallel to the dummy plane that passes tangent to the face of the rotor and which contains the straight line that divides the face transversely into two equal parts , said rotor incorporates its vertices segments and its lateral segments, it also has a cogwheel that rolls and gears on an internal fixed pin, this pinion being integral to the stator, a grinding shaft whose eccentric is housed in the inner hole of the rotor , adjusting between the eccentric and the inner surface of the rotor, a quadruple roller bearing for eccentric articulation, ball and roller bearings for fastening the motor shaft to the stator, flywheel, counterweight to balance the rotor movement , inlet and outlet in the cooling water stator, stator cavities for cooling water circulation, a conduit intake, an exhaust duct, a peculiar safety valve against excessive pressure, a safety valve socket, and a robust glow plug positioned in the auxiliary pre-combustion chamber, also includes; a particular start-up system for starting the engine, peculiar electrical and combustion systems, said auxiliary pre-combustion chamber located at the top of the stator and communicated through a nozzle to the lobe corresponding to the compression phase and where the combustion expansion will begin, special injector for vegetable oil, and special injector for water, both located in the auxiliary pre-combustion chamber, special coating or made of special surface material that delimits the inner hollow in the form of eight of the stator and side walls thereof, special coating or made of special material of some essential elements that make up said engine, such as the three faces of the rotor and its grooves, the intake duct, the exhaust duct, as well as the chamber Pre-combustion auxiliary and its nozzle, also includes two independent fuel tanks (one for vegetable oil and one for water), two independent injection systems (one for vegetable oil and one for water), as well as in its

operation presents certain advances to the injection (one for vegetable oil and one for water). Suitable Engine, so that primarily with its operation it understands and encompasses a procedure to dissociate the hydrogen from the water (electrolytic dissociation of the water molecule) and thus, the bonds of the atoms of the water molecules can be broken, being able to dissociate or fragment said molecule, on the one hand as a hydrogen atom or H + proton, positively charged and dissociated

or loose with respect to the oxygen atom, and on the other hand it is fragmented as negatively charged OH- hydroxyl ions, said process also comprising a peculiar chemical reaction of hydrolysis of water with the esters of vegetable oil. such that the ester molecules dissociate into two fragments. one of which reacts with the atoms or protons H + (of Hydrogen) of the dissociated molecule of water to form carboxylic acid, and the other does it with the hydroxyl ions OH-to form alcohol, producing the quoted chemical reactions practically simultaneous, and linked said chemical reactions and with it the whole process itself, to the operation of the engine proposed in the present invention. Determined said procedure. because said dissociation of hydrogen from water (electrolytic dissociation), as well as the peculiar chemical reaction of hydrolysis of water with esters of vegetable oil are practically carried out simultaneously with their combustion.

The combustion system, which uses the internal combustion and injection injection rotary engine in an auxiliary pre-combustion chamber and in the lobe corresponding to the compression phase, designed so that its operation is carried out using fuels, vegetable oil and water, essentially understands; for each transverse partition of the stator gap, of a rotor, auxiliary pre-combustion chamber attached to the lobe corresponding to the compression phase and where the combustion expansion will begin, nozzle that joins the auxiliary chamber with lobe, motor shaft with its eccentric , glow plug, air filter, intake manifold, and exhaust manifold. Not being necessary in this new engine the carburetor, ignition breaker, or spark-producing spark plugs, mainly this combustion system, in which the engine of the present invention uses two or more special injectors for each division of the internal stator gap ( or by the number of rotors contained in the engine), and at a minimum, one for vegetable oil, and one for water, which inject fuel alternately in the auxiliary pre-combustion chamber and in the lobe corresponding to the compression phase, manufactured said chambers, rotor faces and surface of the interior stator hollow, of special material or with a special coating. With the injection of vegetable oil first, in an approximate proportion or scale with respect to the total injected volume of vegetable oil plus water, between 50% and 99% in volume injected in each combustion, at the time or phase of minimum compression, and then the water injection will be done in an approximate proportion or scale between 50% and 1% in volume injected in each combustion, in the time or phase of almost maximum compression. These proportions can be varied by the desired percentages, as long as the combustion is carried out effectively. the sum of the volume of vegetable oil plus water injected in a combustion in the engine of the present invention, will be similar or equal to the volume of fuel that is supplied at the time of admission in the current rotary engines in one of its combustions, logically attending to the parameters of power and speed of rotation of the motor, analogous for both engines.

The electrical system, which uses the rotary combustion engine of inlema and shared injection in an auxiliary pre-combustion chamber and in the lobe corresponding to the compression phase, designed so that its operation is carried out using fuels, vegetable oil and water, essentially comprises ; battery, starter motor, electrical injection systems, motor shaft with its eccentric, alterator, electric pump submerged in the vegetable oil tank and connected to the vegetable oil injection system for priming fuel at the engine start and several units of electronic control, comprising at least a first electronic control unit, that controls and regulates the synchronization of the multipoint injection of vegetable oil, in each of auxiliary pre-combustion chambers and corresponding lobe, being able to govern the injectors so that the injection of Vegetable oil is carried out in the time or phase of minimum compression, at the right time and frequencies necessary, depending on the speed of rotation of the engine, having the necessary sensors and probes, located in the places that are needed, such as , on the drive shaft, ace! such as the actuators or activators necessary for this function, or the incorporation of any other device that is necessary, and a second electronic control unit, similar to the first, that controls and regulates the timing of the multipoint injection of water, being able to govern the injectors so that the sequential injection in each of auxiliary pre-combustion chambers and corresponding lobe is carried out in the time or phase of maximum compression, at the right time and frequencies necessary, depending on the speed of rotation of the engine, having the sensors and probes necessary and located equally on the drive shaft, as well as the actuators

or activators necessary for this function, or the incorporation of any other device that is necessary. Also with respect to the probes and situations or positions of their terminal sensors on the motor shaft, valid to establish the moments of injection of vegetable oil or water, their positions can be determined, due to the transmission ratio of the fixed piMn and the rotor sprocket, so that the drive shaft turns three times while the rotor takes one, this means that at each turn of the drive shaft, at a given time and position, one of the rotor faces will be positioned in the lobe where the time of almost minimal compression will occur (at which time the oil will be injected

vegetable), and in another determined position of the motor shaft in that same turn, the said face of the rotor will be positioned in the lobe where the time of almost maximum compression will take place (moment in which the water will be injected). And so! repeatedly on the next two other faces

of the rotor. Therefore, the positions where the probes with their respective sensors in relation to the motor axis can be determined, in order to determine the successive moments and times in which the respective injections of both vegetable oil and water will be applied.

the safety valve against excessive pressures, located in the upper part of the steam and located in the lobe where the time or phase of maximum compression of the internal combustion rotary engine will be produced, designed so that its operation is carried out using as fuels, vegetable oil water, will be used in those cases that are necessary, such as when the special coating applied to some. essential elements that make up said engine, such as the auxiliary pre-combustion chamber and its nozzle, said coating would not withstand excessive pressure in the time of maximum compression of the engine, due to its own characteristics or physical properties. Therefore, by lowering the pressure through said valve, said special coatings could be used without difficulty. Likewise, the safety valve will also be used against excessive pressures, in those cases of said engine, in which the excessive pressure in the time of maximum compression of the engine, causes a notable increase in the temperature of the aspirated air, and therefore the elevation temperature in the auxiliary pre-combustion chamber, where appropriate, and in the lobe where the maximum compression time or phase will occur, as well as the excessive temperature rise of the injected vegetable oil. In this case, the safety valve, avoid excessive pressure that causes an excessive increase in the temperature of the injected vegetable oil, thus ensuring that the temperature of the injected vegetable oil is lower than its auto · ignition temperature (minimum temperature so that a product burns spontaneously). This is necessary, to make the mixture with the water that will be injected later. The safety valve against excessive pressures, consists of a device comprising, a conduit made in the upper part of the stator, which communicates at one of its ends with the lobe where the time or phase of maximum compression of the engine will occur and by the other end communicates with the engine exhaust duct through a sleeve. In the part closest to the lobe where the maximum compression time or phase will occur, in said duct that is part of the stator, a metal part is located whose shape is defined by a small sphere and a small cylinder that are centrally intercepted, this that is, the axis of the cylinder parallel to its generatrices intercepts the sphere at its center, the diameter of the sphere being greater than the diameter of the cylinder. Said piece sits on its spherical part on a seat located in the mentioned duct

previously, keeping the duct closed in this part, since said piece is pressed by a spring or spring that sits on the spherical surface of said metal piece and that its internal diameter is tangent (with some slack) to the cylinder of the piece spherical-cylindrical, the spring being at its other end pressed by a thyme with tubular fanna, that is to say, interconnecting this hollow, said thyme having a seat for the spring, thread to be screwed to the outburst, and nozzle or mouth to connect with sleeve or tube that communicates with the exhaust duct. The safety valve for excessive pressures is constituted from it, when the pressure in the lobe where the maximum compression time or phase will occur is propagated from a predetermined value, the

spherical-cylindrical piece will rise from its seat, leaving the existing communication conduit between said lobe and the exhaust duct open, and therefore allowing a flow of compressed air to pass through said conduit, from the lobe containing the maximum pressure to the duct escape, for ace! maintain the necessary and required pressure in the lobe and auxiliary pre-combustion chamber where appropriate. In those cases of design of the present engine where the pressure in the lobe where the maximum compression time or phase will occur does not exceed the predetermined pressure, said safety valve will not be necessary.

The glow plug or glow plugs or heating plugs in the internal combustion rotary engine, whose operation is carried out using fuels, vegetable oil and water, may be located in the stator and located depending on the case, either in the auxiliary pre-combustion chambers, or distributed perimetrically around the stator in the event that there are no pre-combustion auxiliary chambers in the engine, they will be of the type of glow plugs similar to those used in diese / engines, which, as we know, are part of the setting system in operation to start the engine, operating when an electrical circuit is closed by positioning the start switch in its warm position. The operation of said spark plug is simple, it is about passing electric current through an electric resistance located in said spark plug, the resistance is heated, becoming incandescent and giving off a lot of heat, heating the auxiliary pre-combustion chamber and lobe or lobes (limited spaces between the internal stator hole and rotor faces), air and vegetable oil that is deposited in the auxiliary chambers and lobes. The electrical resistance of this spark plug or spark plugs, intended for the engine of the present invention, will be robust enough to raise the temperature of the air and vegetable oil deposited in the auxiliary precombustion chamber and lobe at the time of warm-up for starting. of the engine, at a temperature of approximately 210 "C. If necessary, in each auxiliary chamber and lobe of the motor of the present invention, more than one glow plug can be placed.

The start-up system for starting the internal combustion rotary molor, whose operation is carried out using as fuel vegetable oil and water, mainly comprises in its operation several aspects to be detailed, and which

they are described below; when the start-up switch is operated in its first position (heating position), in addition to closing the electrical circuits that supply the electric energy to the glow plugs and fuel heaters, a third circuit is then activated in a time electric regulated by a timer clock, which activates an electric fuel priming pump, positioned and submerged in the vegetable oil tank, and communicating through some ducts with the accumulator collector (or injection ramp) of the oil injection system plant, allowing said manifold a sufficient pressure so that the injectors (electrically activated) through the holes or diffusers of its nozzle can make one or several simultaneous injections in the different auxiliary pre-combustion chambers and lobes where time or phase will occur of minimal compression, or said injections are made directly especially in the aforementioned lobes in case there were no auxiliary pre-combustion chambers, all at the time of heating the glow plug, without the need for the starter motor to be operated, and consequently without having acted a pressure pump injection. A fourth electrical circuit activated simultaneously and in the same way as the third, will activate the injectors, so that they simultaneously inject vegetable oil. The needle that closes and opens the nozzle of the injector, will be lifted by electromagnetism, hence the existence of this fourth circuit, therefore the electromagnets of the injectors for vegetable oil, may be operated by the circuit mentioned above, as well as when it circuit is deactivated, they can be activated by another circuit that governs an electronic unit. It will be preferable in the warm-up time, a long time injection (of vegetable oil), quickly activated at the beginning of the heating, than several alternate injections, for this, there will be available in this fourth electrical circuit, an automatic switch or timer that disconnects after a certain time, said circuit, of the electricity supplied by the battery. Said switch may be of any type existing on the market such as watches or timers that can meet the desired requirements. Thus, when the start-up switch is operated in its second position (starting position), three of the four previous circuits are disconnected, only the glow plug circuit being connected, and in turn connecting three other circuits , one of them governs the synchronized and sequential injection of the injectors for vegetable oil through an electronic unit, another governs the synchronized and sequential injection of the injectors for water through another electronic unit, and the third circuit will start the Starter, and with this one. high pressure pumps (one for vegetable oil and one for water, in case these pumps are not electric), the drive shaft, flywheel

inertia, etc. In these circumstances, and with a rich volume of vegetable oil in each of the auxiliary pre-combustion chambers, and where appropriate in each lobe where the minimum compression time or phase will occur, the aspirated air and the injected vegetable oil will have heated through the glow plugs at a temperature between 1600 centigrade and 2100 e, and warming even more when one of the rotor faces is in the lobe where the time or phase of maximum compression occurs, the vegetable oil must reach Warm up at a minimum at a critical temperature (which we will explain later), approximately between 160 degrees Celsius and 2100 C. depending on the type of vegetable oil we use. Then when water is injected into the auxiliary pre-combustion chamber and in the lobe where the maximum compression time or phase will occur, or if necessary only in said lobe (if there is no auxiliary pre-combustion chamber), the entire mixture is ignited, burning spontaneously, and thus getting the engine started. Once the rotary engine of the present invention has been started, the starter motor circuit, as well as the glow plug circuit. will be disconnected automatically.

The special injector for vegetable oil, of the internal combustion rotary engine, whose operation is carried out using as fuel vegetable oil and water, will preferably be of the type of injectors used in the electronic injection for diesel engines, such as the type of injectors which use electromagnetic valves and injection control chambers to be activated, or of the type that are activated by a piezoelectric element, but which for motors of this invention, equivalent in power to current rotary motors, comprise some special features, which consist, in that in its nozzle the holes or diffusers of the outlet nozzle where the vegetable oil comes from the injector, will be of a diameter or diameters, whose dimension will be different from that of the injectors currently used, Injection needle that sits on the nozzle, will have at its tip an angle of taper d istinto that of the needles of the current injectors, and also the inner wall of the nozzle near the tip of the injection needle will have a different conicity angle than in the case of the current injectors, also the injection time of these injectors governed by the electronic control unit, will be different from the one used by the current injectors, so that the volume of fuel (of vegetable oil) in the injection made in any phase of revolutions of the engine of the present invention, will be done in an approximate proportion or scale between 50% to 99%, with respect to the volume of fuel that the gasoline rotary engine will use in one of its aspirations at its admission time, or with respect to the sum of the total volume of the mixture (from vegetable oil plus water). All this without prejudice to any other injector and injection percentages other than those, and which are technically permissible.

Differentiating from the current injection systems, because they will use the special injectors for vegetable oil, also the injection time that governs the electronic control unit will be different from that used by the current injectors, so that the volume of fuel (of vegetable oil) in the injection made in any phase of revolutions of the engine of the present invention, it will be done in an approximate proportion or scale between 50% to 99%, with respect to the volume of fuel that I will use the gasoline rotary engine ( equivalent in mechanical power) in one of its aspirations in its admission time, or with respect to the sum

of the total volume of the mixture (of vegetable oil plus water). Also being able to perform injections of vegetable oil volumes, whose percentages are somewhat lower than said, provided that the combustion of the mixture is carried out effectively.

The water injection system of the rotary engine of the present invention will be similar to those existing and known for diese! Engines, with some differences, it comprises; water tank equipped with pre-filter, high pressure pump (which may be optional for installation in the system, depending on whether the water supply for injections is made through a high-pressure electric pump or not), carried by any mechanism of transmission with the motor shaft to be installed, high pressure regulator, electronic control unit with connection strip for sensors and connection strip for actuators or activators, accumulator manifold (or injection ramp), pressure sensor, conduits for water distribution that may be; low pressure suction, high pressure supply, and return, conductors and electrical circuits for sensors and actuators, special injectors for water (defined above), being able to also include in said system, a fuel heater or more than one, in order that the water already enters the hot engine (fundamental for cold areas), and a radiator or fuel cooler, for the water that returns to the tank. Differentiated from the current injection systems, because they will use the special injectors for water, also the injection time that governs the electronic control unit, I will be different and smaller than that used by the current injectors, so that in this system of injection, the volume of fuel (of water) in the injection made in any phase of revolutions of the engine of the present invention, can be done in an approximate proportion or scale between 1% to 50%, with respect to the volume of fuel that will be used by the rotary gasoline engine (equivalent in mechanical power) in one of its aspirations in its admission time, or with respect to the sum of the total volume of the mixture (vegetable oil plus water). Also being able to perform injections of water volumes, whose percentages are somewhat higher than said, as long as the combustion of the mixture is carried out effectively.

The advance to the injection. Since the rotary engine of the present invention of internal combustion, its operation is carried out using as fuel vegetable oil and water. And that as we have seen for its operation, it comprises and uses certain chemical reactions (electrolysis and hydrolysis) activated and derived from the mixture between vegetable oil, water and air, under certain environmental conditions. such as the surface of the enclosure where the mixture takes place '1 the surrounding temperature, and ending said chemical reactions with the combustion of the mixture. Therefore, in this new rotary engine that is proposed, the advance to the injection must be taken into account, with preferential attention to the ignition of the mixture (air, vegetable oil and water), which, in fact, of the present molor It is manifestly merged with the advance to the injection, both to the advance of the injection of the vegetable oil and to the advance of the water injection. Consisting of these advances, in which the necessary time parameters in which the chemical reactions are obtained, as well, must be foreseen and measured. such as the time of propagation and inflammation of the total mixture in combustion. Since the combustion of the entire mixture, in fact it is not done instantaneously, if it is progressively inflamed, it is true that it will be done very quickly, but with a minimum delay, to all this, the times must be added of injection of vegetable oil and water, governed by the electronic control units (both connected to their respective probes and sensors, which will determine the position of the motor shaft at a given time and therefore the position of the rotor), which

They will provide the advance to advance the injection of vegetable oil at the time and the advance to advance the injection of water at the time, so that the combustion of the mixture occurs without delay, and providing that the entire expansion force of the combustion is applied successively and alternately on each of the three faces of the roller. Said advances will be made proportionally to the speed of rotation of the motor, so that said advances will be much greater, the faster the motor of the present invention rotates.

Ace! therefore, according to this first embodiment of the present invention of the internal combustion rotary engine, of shared injection in an auxiliary pre-combustion chamber and in the lobe corresponding to the compression phase, designed so that its operation is carried out using as fuels, Vegetable oil and water, can be defined particularly in its operation, because its progress to the injection, is that the injection of vegetable oil, is carried out in a shared way in a special auxiliary pre-combustion chamber and in the lobe corresponding to the compression phase, in the minimum compression time, when one of the rotor faces is beginning the compression time, and the water injection is carried out in the said special pre-combustion auxiliary chamber and in the lobe corresponding to the compression phase or time, moments before the aforementioned face of the rotor is positioned in the lobe of maximum compression. Depending on the position of the rotor face at the time of the water injection, at the advance of the water injection, and also depending on the position of the rotor face at the time of the oil injection, at the advance of the injection of the Vegetable oil Being

such advances are greater, the faster the engine rotates. All regulated by the

two electronic control units of injection systems (one for vegetable oil,

and the other for water), which through its sensors and probes, as well as its actuators or

triggers, will determine the appropriate parameters at all times, for advances to the

5

injection, both for vegetable oil and for water.

Thus, according to this first embodiment of the present invention that

it is proposed, a new rotary internal combustion, injection engine is provided

shared in a pre-combustion auxiliary chamber and in the lobe corresponding to the phase

10

compression, designed so that its operation is carried out using as fuels,

vegetable oil and water, particularly defined in its operation, by the conflQuration

of some of its times, phases and moments in which the injections of the

fuels (vegetable oil and water). For a better understanding of how this works

First embodiment of the present rotary motor. defined here below their

fifteen

different times, these progressively referred only to one of the rotor faces, with their

respective and particular characteristics (phases, injection moments, etc.). Is to understand

as you know, when the rotary engine is running, in the different lobes

delimited by the faces of the rotor and inner hole of the burst, several are being produced

times at a time, but for a detailed study, we do here the monitoring of

twenty

different times or phases of this motor with respect to one of the rotor faces, as already

He said earlier.

At the time or phase of admission, air is first conducted through the duct

of admission to the admission lobe and then to the auxiliary chamber of

25

pre-combustion, while the rotor face (one of the three rotor faces chosen for this

study) is moving away from the mouth or embrasure of the intake duct. Defining this

engine in this phase or admission time, because in it, the entry of the

fuel in the engine.

30

In compression time, this new rotary engine is defined, because when the

face (chosen) of the roll has exceeded the intake pocket and the air is beginning to be

compressed, the vegetable oil will be injected in a shared way into the auxiliary chamber of

pre-combustion and in the lobe corresponding to the phase of minimal compression on the face

of the rotor, then when the rotor face has advanced to almost form the lobe of

3 s

maximum compression, air and vegetable oil deposited in the auxiliary chamber of

pre-combustion and lobe, when compressed they heat up and rapidly increase their

temperatures, reaching the vegetable oil a temperature between its "critical temperature ~

(between 1600 e. and 2100 e., depending on the type of vegetable oil we use) and its

.

~ auto-ignition temperature ~ (minimum temperature for a product to burn spontaneously), but without reaching the latter, the water will be injected immediately, also shared in the auxiliary pre-combustion chamber and in the lobe corresponding to the almost maximum compression phase. The safety valve against excessive pressure may be kept closed or momentarily open if the pressure in the maximum compression and auxiliary pre-combustion chamber exceeds the predetermined pressure indexes.

In the burning time, also called work, force, expansion etc. This new rotary engine can be defined in this phase, because when mixed in the previous phase of maximum compression, air, and vegetable oil with water in the expected percentages and required environmental and temperature conditions, the chemical reactions before said and defined (electrolysis and hydrolysis), the combustion of the mixture being obtained practically simultaneously, and all the expansive force due to the gases of the combustion concentrated in a minimum volume in the auxiliary pre-combustion chamber and lobe of maximum compression, is applied on the face of the rotor, pushing the rotor with great force and thus spinning it, the combustion expansion developing in its movement.

In the time of escape or expulsion, the rotor with its rotary movement and one of its faces, will move the combustion gases and fumes towards the exhaust vent, thus causing said gases to escape through the exhaust duct, which will subsequently reach the exhaust pipe and its exit to the outside. As we see in this last phase, it seems that there are no differences with respect to the exhaust phase of other rotary engines, and this new engine can only be characterized in this phase in a remarkable way, because the exhaust gases, coming from organic alternative fuels and ecological (vegetable oil and water) are less polluting than gases from the combustion of fossil fuels (gasoline or diesel).

According to a second embodiment of the present invention, similar to the engine defined above, for a new rotary internal combustion engine, designed for operation using fuels, vegetable oil and water, this second embodiment is particularly defined, because its injections of fuels, both vegetable oil and water, are made directly in the lobe of the engine destined for compression time, without any auxiliary pre-combustion. Therefore, unlike the first embodiment, the special injector for vegetable oil, the special injector for water, as well as the robust spark plug or glow plugs, will be located in the engine stator, placing the injectors in the lobe

corresponding to the compression time and glow plugs located and

distributed in addition to the compression section, in the rest of lobes belonging to the

intake, combustion and exhaust times, and even in the air intake duct if

if necessary, all in order to heat the engine for start-up, being

combustion, special injector for vegetable oil, and special injector for water, located

both in the lobe corresponding to the phase or compression time, special coating

or made of special material of the surface that delimits the interior hollow in the form of

30

eight of the stator and side walls thereof, special coating or made of material

special of some essential elements that make up said engine, such as; the

three faces of the rotor and its slits, the intake duct, and the exhaust duct,

It also includes two independent fuel tanks (one for vegetable oil

and airo for water), two independent injection systems (one for vegetable oil and another

3S

for water), as well as in its operation it presents certain advances to the

injection (one for vegetable oil and one for water). Fit said engine, so that

primarily in its operation understand and encompasses a procedure to dissociate the

Water hydrogen (electrolytic dissociation of the water molecule) and encompasses a peculiar

hydrolysis reaction of the water with the esters of the vegetable oil, linked said chemical reactions and with it the whole process in sf, to the operation of the rotary mill proposed in the present invention. Determined said procedure, because said dissociation of hydrogen from water (electrolytic dissociation), as well as the peculiar chemical reaction of hydrolysis of water with the esters of vegetable oil are practically simultaneous to their combustion.

The combustion system, which uses the internal combustion rotary engine in this second embodiment, is similar to the one used in the first embodiment of this invention, with the exception that in this second embodiment, the Special injectors for vegetable oil and water, injected directly into the lobe of the. engine intended for compression time, without any auxiliary pre-combustion chamber.

All the systems and elements that are expressed below, which uses this second embodiment of the internal combustion rotary engine. designed so that its operation is carried out using as fuels. vegetable oil and water, as they can be; lubrication, electrical, cooling, start-up, vegetable oil injection, and water injection systems, as well as the rotor, safety valve against excessive pressures, glow plugs or heating, the special oil injector Vegetable, as well as the special water injector, are the same systems and elements as defined above for the first embodiment of the engine of the present invention, and its equivalent operations for both embodiments of the proposed engine.

The different embodiments. of the special coating or manufactured of special material, of the surface that delimits the inner hollow in the form of eight of the stator and side walls thereof, as well as the special coating or manufactured of special material of some essential elements, such as the three faces of the rotor and its grooves, the intake duct and the exhaust duct, are the same embodiments as defined above for the first embodiment of said engine.

In this second embodiment of the internal combustion rotary engine, whose operation is carried out using as fuel vegetable oil and water, it also comprises two independent tanks for fuel, one for vegetable oil and one for water. It also includes two independent injection systems, one for vegetable oil and one for water.

The advance to the injection in this second embodiment of the internal combustion engine that its operation is carried out using as fuel vegetable oil and water, is analogous to that expressed and defined above for the first embodiment, differing exclusively in that in this case the injections of both

5 vegetable oil and water oil are made directly in the engine lobe for compression time, without any auxiliary pre-combustion.

Thus, according to this second embodiment of the present invention that is proposed, a new internal combustion rotary engine is provided, whose injections are made directly in the lobe of the engine destined for the compression time, without any auxiliary chamber pre-combustion, designed so that its operation is carried out using as fuel, vegetable oil and water. In its operation, configuration of its times, phases and moments in which fuel injections (vegetable oil and water) occur, is similar to the first embodiment, but not

15 However, for a better understanding of the operation of this second embodiment of the present engine, its different times are defined here, with their respective and particular characteristics (phases, injection moments, etc.).

At the time or phase of admission, air is conducted through the intake duct

20 to the intake lobe, while the rotor face (one of the three rotor faces chosen for this study) moves away from the mouth or embrasure of the intake duct. Defining this engine in this phase or time of admission, because in it, the entry of fuel into the engine is not made.

25 At the time of compression, this new rotary engine is defined, because when the (chosen) face of the rotor has exceeded the intake pocket and the air is beginning to be compressed, the vegetable oil will be injected into the lobe corresponding to the Minimum compression rate, on the rotor face, then when the rotor face has advanced to almost form the lobe of maximum compression, air and vegetable oil deposited in the

30 lobes, when compressed, heat and rapidly increase their temperatures, reaching the vegetable oil a temperature between its critical temperature and its self-ignition temperature, but without reaching the latter, immediately afterwards the water will be injected into the lobe corresponding to the almost maximum compression phase. The safety valve against excessive pressure may be kept closed or momentarily open if the pressure in the

35 the maximum compression lobe will exceed the default Pressure Indices.

In the burning time, also called work, force, expansion etc. This new rotary engine can be defined in this phase, because when mixed in the previous one

of the combustion concentrated in a minimum volume in the lobe of maximum compression,

apply on the face of the rotor, pushing the rotor with great force and thus turning it,

taking in its movement the development of the combustion expansion.

In the time of escape or expulsion, the rotor with its rotary movement and one of the

10

faces of the latter, will move the combustion gases and fumes towards the exhaust vent,

causing in this way that these gases exit through the exhaust duct, which

later they will reach the exhaust pipe and its exit to the outside. As we see in the latter

phase, apparently there are no differences with respect to the exhaust phase of other engines

rotary, and only this new engine can be characterized in this phase in a remarkable way,

1 S

because exhaust gases, coming from organic and ecological alternative fuels

(vegetable oil and water) are less polluting than the gases coming from the

combustion of fossil fuels (gasoline or diesel).

important, compared to most of the internal combustion engines used in the

present. Thus, the present invention is constituted, in its embodiments,

components and elements that compose it, not in any way intended to be in their

forms of realization, or elements that constitute them imitative of their scope.

30

As indicated above, a second object of the present invention is

It refers primarily to a process for dissociating hydrogen from water (dissociating

water molecule), said hydrogen dissociation, as a

transformation or primary or primary chemical reaction, which is encompassed and chained with

a peculiar chemical reaction of hydrolysis of water with esters of vegetable oil,

35

the aforementioned virtually simultaneous chemical reactions occurring, and linked said

chemical reactions and with it, the whole procedure itself, to the operation of the engine that

It is proposed in the present invention. Characterized said procedure, because said

dissociation of hydrogen from water (electrolytic dissociation), as well as the peculiar reaction

Chemistry of hydrolysis of water with esters of vegetable oil are practically carried out simultaneously with their combustion.

Said procedure may be carried out in any place where the optimum and necessary conditions exist, and of course in the auxiliary pre-combustion chambers and lobes corresponding to the maximum compression time of the different embodiments of the rotary engine of the present invention.

Since the procedure to which we are referring, is actually a transformation or chemical reaction between two components (not counting the air), such as, vegetable oil and water, (which as we know are not soluble in each other) and that As in any chemical reaction, the materials in contact with the components to be reacted can also interact or react in said reaction, either positively to our expectations or negatively to our expectations. It will therefore be necessary, on the one hand, to provide by means of the practice of trial and error, the most suitable materials to be used in the realization or manufacture of the auxiliary pre-combustion chamber, as well as the materials of the elements that will delimit the lobes motor (rotor faces and stator inside hole), places where the aforementioned chemical reaction will occur in the motor. And on the other hand, it will be necessary to know and specify for practice, certain specific properties of the components that will be part of the reaction (vegetable oil and water), as well as the detailed process to be followed in the places where the said chemical reactions within the engine, either a rotary injection engine shared in a pre-combustion auxiliary chamber and in the lobe corresponding to the compression phase,

or of direct injection into the lobe corresponding to the compression phase, in the same way the volumes of fuels injected from vegetable oil and water should be determined, and finally, the basic guidelines in which the aforementioned chemical reactions will develop must be determined, within the rotary engine of the present invention, all of this, in order to obtain the expected result, that is, as a primary objective, the dissociation of hydrogen from water (electrolytic dissociation), and encompassing a peculiar chemical reaction of hydrolysis of water with esters of vegetable oil. In such a way that these reactions are restarted practically simultaneous to their combustion.

Accordingly, said procedure comprises the following steps:

a) The determination by means of trial and error practice of the most suitable materials to be used in the realization and manufacture of the auxiliary pre-combustion chamber, as well as the most suitable materials to make the elements that will delimit the engine lobes (rotor faces and stator inside hole), places where the aforementioned will occur

chemical reaction in the engine. Being able to make or manufacture said chambers, rotor and its three faces and inner hollow of the burst, with the following materials: stainless steel, either with an alloy of iron, carbon, chromium and nickel, or whose alloy is made only with, iron, carbon and nlque !.

of steel with a coating of n / que !.

made of aluminum or steel with a special coating of several layers of Polytetrafluoroethylene, except for the interior gap of the stator that it will not be advisable to carry the Polytetrafluoroethylene coating.

of steel with a ceramic coating or vitrified enamel or VitrO-ceramic.

of any other material that, through the practice of trial and error in laboratory experimentation, plausible results have been obtained with respect to the desired reaction.

Being able to use these materials interchangeably, in the different parts before said of the engine, without having to be the materials used exclusively of a soto type.

b) The determination of the specific properties of the components that will be part of the reaction (vegetable oil and water), such as the different temperatures reached by the components and derivatives in the reaction, necessary for the practice and understanding of the procedure, such as They are:

each one of the "critical temperatures · of the different vegetable oils that we could use, from which, the heated vegetable oils, begin to smoke and decompose. It would need that critical temperature of the vegetable oil, because from it and at temperatures higher, when spraying water or water vapor on the vegetable oil in a suitable environment (auxiliary pre-combustion chamber where appropriate or maximum compression lobe, of the engine of the present invention), the main reaction will occur

or desired primary, that is, the dissociation of hydrogen from water, said dissociation understood, as a primary or primary chemical transformation or reaction, which is encompassed and chained with a peculiar chemical reaction of hydrolysis of water with the esters of vegetable oil, of such that said dissociation of the hydrogen from the water, as well as the chemical reaction of hydrolysis of the water with the esters of the vegetable oil are practically carried out simultaneously with their combustion. Said -critical temperatures ~ for the different vegetable oils, will be approximately;

for olive oil 210 degrees Celsius. for sunflower and soybean oil 1700 c.

• for rapeseed and maize oil 1600 c.

the auto · ignition temperature (mloíma temperature for a product to spontaneously burn) of the vegetable oil, depending on the type of oil being: approximately between 52SO C. and 6200 centigrade.

Since the water molecules are formed by H20, that is, two atoms of Hydrogen and one of Oxygen, and that water is a primary component of the reaction, when dissociating hydrogen, it will also be interesting to know,

The hydrogen auto-ignition temperature, which is around 5800 c.

Also given that the hydrolysis of water with esters of vegetable oil. It is part of the reaction, and that as we know, two compounds are mixed with it, such as carboxylic acid and alcohol, it is also interesting to know;

the aulo-ignition temperature of carboxylic acid, which is approximately 4250 c. The auto-ignition temperature of alcohol, which depending on the type of alcohol is approximately between 3780 C and 4600 C.

c) The determination and detailed description of the process to be followed, in the places where the said chemical reaction will take place in the internal combustion rotary engine proposed. and that said reactions will be carried out;

In the auxiliary pre-combustion chambers and lobes attached to said chambers, the aforementioned lobes corresponding to the maximum compression phase, or the reactions occur only in said lobes, when the engine of the present invention does not have the auxiliary chambers of precombustion. Consequently, fuel injections (of vegetable oil and water) will be carried out, either in a shared injection in the auxiliary pre-combustion chamber and in the lobe corresponding to the compression phase, or in direct injection in the lobe corresponding to the compression phase. when the rotary engine does not have a pre-combustion auxiliary chamber. Said process will be developed with the operation of the engine, when the injection of vegetable oil is carried out, either in a shared injection in the auxiliary pre-combustion chamber and in the lobe corresponding to the minimum compression phase, or said injection is made directly in the lobe corresponding to the minimum compression phase, when there is no auxiliary pre-combustion chamber in the rotary engine, said injection being made, when one of the rotor faces has exceeded the air intake nozzle. Then the water injection will be carried out, either in a shared injection in the auxiliary pre-combustion chamber and in the lobe corresponding to the maximum compression phase, or said injection is carried out directly in the lobe corresponding to the maximum compression phase when the engine The rotary chamber does not have an auxiliary pre-combustion chamber, making the aforementioned injection, slightly before the corresponding face of the rotor forms the lobe of maximum compression. Depending on the distance and position of the rotor face to its position where it generates the

lobe of maximum compression, to the advance of the water injection, and also depending on the distance and position of the face of the rotor to one of its positions in which it generates one of its lobes of minimum compression, to the advance of the injection of the vegetable oil . These advances being so much greater, the faster the engine rotates. With the start-up of the rotary engine (warm-up time with the glow plug of the auxiliary pre-combustion chamber and lobe destined for the compression phase and for the case of the engine that does not have an auxiliary chamber, heating of the other lobes of the engine, as well as the heating of the deposited air and vegetable oil and the action of the starter motor), and the starting of the mime, the auxiliary pre-combustion chamber where appropriate and lobe destined for the compression phase will be hot, when injected the vegetable oil in the time of almost minimal compression, when one of the rotor faces delimits the lobe of almost minimal compression, the vegetable oil is injected, acquiring temperature of the auxiliary pre-combustion chamber, rotor face and lobe intended for compression , increasing said temperature of the vegetable oil in the time of maximum compression (compression of the aspirated air and the injected vegetable oil) and before that the water injection occurs, that is, before one of the three faces of the rotor delimits the maximum compression lobe, the temperature at which the used vegetable oil will rise, in these circumstances, will be at least its -critical temperature-and as a maximum temperature, any temperature below its auto-ignition temperature. Then when one of the three faces of the rotor is in a certain position, close to the delimitation of the maximum compression lobe and before reaching it, water injection is performed in the auxiliary pre-combustion chamber and lobe of almost maximum compression , or only in the aforementioned lobe if the engine did not have an auxiliary chamber. When spraying the water or water vapor on the vegetable oil, which as we have said before will be at a certain temperature between its critical temperature and its self-ignition temperature (without reaching the latter), the main or primary reaction will occur desired, that is, the dissociation of hydrogen from water or fragmentation of the water molecule, said dissociation being understood as a transformation

or primary or primary chemical reaction, which is encompassed and chained with a peculiar chemical reaction of hydrolysis of water with the esters of vegetable oil, such that said dissociation of hydrogen from water, as well! as the peculiar chemical reaction of hydrolysis of water with the esters of vegetable oil are practically simultaneous to their combustion.

d) The determination of the volumes of fuels to be injected (of vegetable oil and water), in the possible embodiments of the engine that is proposed, either with or without auxiliary pre-combustion chambers, the volume of vegetable oil injected into the chamber auxiliary pre-combustion and lobe for minimal compression, or volume of vegetable oil injected only in lobe for minimal compression, if there is no auxiliary chamber in the engine, in both cases, it will be the injection made at any stage of engine revolutions of the present invention and will be made in an approximate proportion or scale between 50% to 99%, with respect to the sum of the total volume of the mixture

(from vegetable oil plus water). Also being able to perform injections of vegetable oil volumes, whose percentages are even somewhat lower than those said. The volume of water has to be injected into the auxiliary pre-combustion chamber and lobe for almost maximum compression, or the volume of water has to be injected only into the lobe intended for almost maximum compression if there is no auxiliary chamber in the engine, in both cases, the injection carried out in any phase of revolutions of the engine of the present invention and will be done in an approximate proportion or scale between 1% to 50%, with respect to the sum of the total volume of the mixture (of vegetable oil plus water) . Also being able to perform injections of water volumes, whose percentages are even somewhat higher than said. The indices or scales between the percentages that have been previously expressed for vegetable oil and for water, are estimates and approximate and never limiting any other percentage that could be used, since these percentages will vary depending on the different technical relationships with the that the rotary motor be configured, such as; the compression ratio, the expansion ratio and the stoichiometric ratio. Therefore, within the limits or scales indicated above, the percentages of vegetable oil and water may be used, more suitable for each specific case of the engine of the present invention, depending on the technical characteristics with which it is manufactured. Ace! for example, we could have an engine that used in its combustion, a volume of the mixture, 80% vegetable oil and 20% water, or any other percentage that complement each other in relation to the indicated ranges.

e) The determination and detailed description of the basic guidelines in which the aforementioned chemical reactions are developed in the engine of the present invention, whether or not it has auxiliary pre-combustion chambers. As we know, vegetable oils or triglycerides are organic compounds that consist of esters formed by three molecules of unsaturated fatty acids (oleic acid) and one molecule of alcohol (glycerin). And therefore, we can say that an ester is a compound formed by the combination of a fatty acid with glycerin. Well, the basic guidelines in which the aforementioned chemical reactions are developed will be determined and described in the following lines; When vegetable oil is heated by the means described above, that is, with glow plugs, compression of air and vegetable oil (through one of the three faces of the rotor) located or entered the air and oil in an auxiliary pre-combustion chamber and lobe intended for almost maximum compression or only entered into said lobe if the engine did not have an auxiliary chamber (manufactured or coated said chamber and elements that delimit the lobe of the aforementioned materials for the present engine

invention), until the vegetable oil reaches its critical temperature or higher temperatures (without reaching its self-ignition temperature), the vegetable oil decomposes releasing its ester chains. Under these circumstances, when water or steam is sprayed

of water on the vegetable oil, the esters of the oil (oil molecules) react with the water (water molecules, H ~), dissociating (electrolytic dissociation of the water molecule) or fragmenting said water molecule, on the one hand, as a hydrogen atom or proton H +, positively charged and dissociated or sued with respect to the oxygen atom, when the bond with the oxygen atom is broken, and on the other hand it is fragmented as hydroxyl ions OH ", negatively charged, so which, the fragmented water molecules react with the esters of the vegetable oil, also encompassing in the process, a chemical reaction of hydrolysis, reaction of the water with the esters of the vegetable oil, so that the ester molecules dissociate in two fragments, one of which reacts with atoms or protons H + (of hydrogen) of the dissociated molecule of water to form the carboxylic acid, and the other does it with the hydroxyl ions OH-pair to form alcohol, producing the aforementioned virtually simultaneous chemical reactions. and characterizing said reactions, because the aforementioned dissociation of! Water hydrogen (electrolytic dissociation), as well as the chemical hydrolysis reaction, of water with the esters of vegetable oil are practically carried out simultaneously with their combustion. Therefore, the final reaction produced, we could say that it would be a special type of saponification reaction whose final result is the combustion of the mixture.

At the temperature of the vegetable oil at which the chemical reaction occurs (between its critical temperature and its self-ignition temperature), the caloric energy due to the breakage of the bonds of hydrogen atoms with the atom of hydrogen must be added oxygen of the water molecule, as well as the heat released from the aforementioned hydrolysis reaction, reaching at this stage of the reaction, a temperature higher than the self-ignition temperature of hydrogen, vegetable oil, and where appropriate the carboxylic acids and decomposed alcohols, producing spontaneous combustion of the entire mixture.

According to the first embodiment (1) of this invention, the rotary injection engine shared in a pre-combustion auxiliary chamber and in the corresponding lobe to the compression phase, designed so that its operation is carried out using as fuels, vegetable oil and water, It can be defined particularly in its operation, by configuring its times, phases and times when fuel injections (vegetable oil and water) occur. Ace! therefore, for a better understanding of the operation of this first embodiment, they are defined below, with

15 reference to the figures from fig. 1 O to fig. 21, its different times, with their respective and particular characteristics (phases, injection moments, etc.), as! as the different and successive positions of the rotor in a cycle, said cycle referenced, in relation to the successive positions of the AC face of the rotor, in which its three faces have been defined, naming the rotor vertices as, A, By C.

20 Accordingly from figure 10 to figure 13 and with respect to the AC face of the rotor (5), said figures represent the admission time of the rotary motor (1), in which with the movement of the rotor (5) it allows the air inlet (75) to the lobe or intake lobes (76) and to the auxiliary pre-combustion chamber (27). Defining this first embodiment (1)

25 of the rotary engine, in this phase, because the sucked air (75) from the intake duct (14), is conducted through the intake lobe or lobes (76) to the special auxiliary pre-combustion chamber (27), when the vertex C of the AC face of the rotor (5) passes through the mouth or port of the inlet condiment (14).

30 Figures 14, 15 and 16, with respect to the AC face of the rotor (5), represent the compression time of the rotary motor (1). Defining this first embodiment (1) of the rotary engine, in this phase, because the injection of vegetable oil (77) is carried out by the special injector (19) shared in the auxiliary pre-combustion chamber (27) and in the corresponding lobe to the phase of almost minimal compression (78) on the AC face of the rotor

35 (5), And while the rotor (5) and its face AC rotate from the delimited lobe of almost minimal compression (78) to delimit the lobe of maximum compression (79) the air and vegetable oil deposited in the auxiliary chamber of pre-combustion (27) and on the AC side of the rotor (5), when compressed, they quickly heat up and increase their temperatures, the vegetable oil reaching a temperature between its critical temperature and its self-ignition temperature, but without reaching it Last, then and shortly before the AC face of the rotor (5) reaches to delimit the maximum compression lobe (79), the shared injection of water (80) is carried out on the auxiliary pre-combustion chamber (27) and on the AC face of the rotor (5) (on the vegetable oil), supplied with said injection by the special injector (20), at which point the chemical reactions (electrolysis and hydrolysis) and the ignition of the mixture begin. the safety valve against excessive pressures (16) may be kept closed or momentarily open if the pressure in the maximum compression lobe (79) exceeds the predetermined pressure indexes.

Figures 17, 18, and 19, with respect to the AC face of the rotor (5), represent the combustion time (also called work or force) of the rotary engine (1). Defining this first embodiment (1) of the rotary engine, in this phase, because when mixed in the previous compression phase, the air, and the vegetable oil with the water in the expected percentages and required environmental and temperature conditions, they produce the aforementioned and defined chemical reactions (electrolysis and hydrolysis), obtaining almost simultaneously the combustion (81) of the mixture, and all the expansive force due to the combustion gases (81) concentrated in a minimum volume in the auxiliary chamber of pre-combustion (27) and in the lobe corresponding to the time or phase of maximum compression (79), it is applied on the rotor AC face (5), pushing it and turning it with great force in the direction of rotation of the rotor ( 5).

Differentiating this first embodiment (1) of the rotary engine, at this stage in a remarkable way, because the exhaust gases (82), coming from alternative organic and ecological fuels (vegetable oil and water) are less polluting than the gases coming from the combustion of fossil fuels (diesel or gasoline).

According to the second embodiment (1a) of this invention, the direct injection rotary engine in the lobe corresponding to the compression phase, designed so that its operation is carried out using fuels, vegetable oil and water, can be defined particularly in its operation, by the configuration of their times, phases and moments in which the injections of fuels (vegetable oil and water) occur.

(83) to the lobe or admission lobes (84). When the vertex D moves away from the DF face of the rotor (5) of the intake port, the intake lobe (84) acquires a greater volume and therefore a greater volume of air (83) drawn.

Figures 26, 27 and 28, with respect to the DF face of the rotor (5), represent the compression time of this second embodiment (1a) of the rotary motor. Defining this second embodiment (1a) of the rotary engine in this phase, because the injection of vegetable oil (85) is carried out by the special injector (19) directly in the lobe corresponding to the phase of almost m / nim compression (86 ) on the DF side of the rotor (5), and while the rotor (5) and its DF face rotate from the delimited lobe of almost minimal compression

(86) until the maximum compression lobe (87), the air and the vegetable oil deposited on the DF side of the rotor (5) are delimited, when compressed, they quickly heat up and increase their temperatures, reaching the vegetable oil a temperature between its critical temperature and its auto-ignition temperature, but without reaching the latter, then and shortly before the DF face of the rotor (5) reaches to delimit the lobe of maximum compression (87), the injection of water (88) on the DF side of the rotor (5) (on the vegetable oil), said injection being supplied by the special injector (20), at which point the chemical reactions (electrolysis and hydrolysis) and the ignition of the mixture are initiated . the safety valve against excessive pressures (16) may be kept closed or momentarily open if the pressure in the maximum compression lobe (87) exceeds the predetermined pressure Indices.

Figures 29, 30, and 31, with respect to the DF face of the rotor (5), represent the combustion time (also called work or force) of this second embodiment (1a) of the rotary engine. Defining this second embodiment (1a) of the rotary engine in this phase, because when mixed in the previous compression phase, the air, and the vegetable oil with the water in the expected percentages and required environmental and temperature conditions, occur the chemical reactions mentioned above and defined (electrolysis and hydrolysis), practically obtaining simultaneously the combustion (89) of the mixture, and all the expansive force due to the combustion gases (89) concentrated in a minimum volume in the lobe corresponding to the time or phase of maximum compression (87), is applied on the DF face of the rotor (5), pushing it and turning it with great force in the direction of rotation of the rotor (5).

Figures 32, 33 and 22, with respect to the DF face of the rotor (5), represent the escape or expulsion time of this second embodiment (1a) of the rotary engine. Once the vertex O of the OF side of the rotor (5), in its rotating movement, exposes or exceeds the embrasure or port of the exhaust duct, the DF face of the rotor (5) will move the gases and fumes (90) from the combustion towards the aforementioned port, thus causing said gases (90) to escape through the exhaust duct (15), which will subsequently reach the exhaust pipe and its exit to the outside. Differentiating this second embodiment (1a) of the rotary engine in this phase in a remarkable way, because the exhaust gases (90), coming from alternative organic and ecological fuels (vegetable oil and water) are less polluting than the gases coming from of the combustion of fossil fuels (diesel or gasoline).

Everything, helping us in part of the figures described above and referring to some elements referred to in them. So that;

Not being necessary in this new rotary engine, the carburetor, ignition breaker, or spark-producing spark plugs, this combustion system consisting mainly of the fact that in the embodiment fan (1) and (la) of the engine of the present invention, they use two or more special injectors for each division of the internal gap (3) of the stator (2) 6 (2a) (or by number of rotors that the motor contains), and at least one for vegetable oil (19), and another for water (20), which will inject fuel alternately in the auxiliary pre-combustion chamber (27) and in the lobe corresponding to the compression phase, for the form of

Injecting vegetable oil first, in an approximate proportion or scale with respect to the total injected volume of vegetable oil plus water, between 50% and 99% in volume injected in each combustion, at the time or phase of almost minimal compression , and then the water injection will be done, in an approximate proportion or scale between 50% and 1% in volume injected in each combustion, in the time or phase of almost maximum compression. Being able to vary these proportions in the desired percentages, as long as the combustion of the mixture is carried out effectively. The sum of the volume of vegetable oil plus water injected in a combustion in the engine of the present invention, will be similar or equal to the volume of fuel that is aspirated at the time of admission, in the current gasoline rotary engines in one of its combustions , logically according to the parameters of power and speed of rotation of the motor, analogous for both engines.

The electrical system (not shown in the figures, but we can see some of its elements in Figures 1, 2, 8 and 9), which uses the two embodiments (1) and (1a) of the internal combustion rotary engine four-stroke, designed so that its operation is carried out using fuels, vegetable oil and water, essentially includes; battery, starter, electric injection systems (42) and (59), motor shaft

(12) with its eccentric (13), alternator, electric pump (55) submerged in the vegetable oil tank (53), and connected to the vegetable oil injection system (42) for the priming of fuel at the start of the engine (1) 6 (1a) and several electronic control units, such as the electronic control unit (56) for the vegetable oil injection system (42) and the electronic control unit (72) for the injection system of the water (59), comprising at least a first electronic control unit (56), which controls the timing of the multipoint injection of the vegetable oil, being able to

Also with respect to the probes and situations or positions of their terminal sensors on the motor shaft (12) of both embodiments (1) and (1a) of the engines, valid for establishing the moments of injection of vegetable oil or water , their positions can be determined, due to the transmission ratio of the fixed pinion (11) and the toothed wheel (10) of the rotor (5), whereby the drive shaft (12) turns three times while the rotor (5) give one, this means that at each turn of the drive shaft (12), at a given time and position thereof, one of the faces (6) of the rotor (5) will be positioned in the lobe where the time of almost Minimum compression (at which time the vegetable oil will be injected), and in another determined position of the molar axis (12) on that same turn, the said face

(6) of the rotor (5) will be positioned in the lobe where the time of almost maximum compression will occur (at which time the water will be injected). And so! repeatedly on the next two other faces (6) of the rotor (5). Therefore, the positions where the probes with their respective sensors in relation to the motor axis (12) can be determined, for as! determine the successive times and times in which the respective injections will be applied, both from vegetable oil and from water.

the glow plug or glow plugs (18) or heating in the two embodiments (1) and (la) of the rotary engine depicting figures 1 and 2, of internal combustion, that its operation is performed using as fuel, oil Vegetable and water, may be located in the stator (2) or (2a) and located depending on the case, either in the auxiliary pre-combustion chambers (27) of the engine (1) or distributed perimeter around the heat (2a) of the engine (1a) ) in the case that they did not exist in the rotary engine <: auxiliary pre-combustion belts (27), they will be of the type of glow plugs similar to

which are used in diesel engines, which, as we know, are part of the start-up system for starting the engine, being activated when an electric circuit is closed by positioning the start-up switch in its heating position. The operation of said spark plug (18) is simple, it is about passing electric current through an electric resistance located in said spark plug (18), the resistance is heated, becoming incandescent and giving off a lot of heat. thereby heating the auxiliary pre-combustion chamber (27) and corresponding lobe of the engine (1), or heating the lobes (spaces delimited between the inner hollow (3) of the stator and rotor faces (5)) of the engine (1a), yasl also heating the air and vegetable oil that is deposited in the auxiliary chambers where appropriate and corresponding lobes. Resisting its difference with [as current glow plugs in that [the electrical resistance of this spark plug or spark plugs (18), intended for the engine of the present invention, will be robust enough to raise the temperature of the air and deposited vegetable oil in the auxiliary pre-combustion chamber where appropriate and [corresponding obe, or lobes [for the case of the engine (1 a), at the time of heating for the engine start, at a temperature of approximately 2100 C (or lower depending on the type of vegetable oil that was used). If necessary, in each auxiliary chamber (27) and lobe where appropriate, or lobes for the case of realization (1a) of the engine of the present invention, more than one glow plug may be placed.

E [start-up system for starting the rotary engine in its four-stroke internal combustion (1) or (1a) internal combustion forms, that its operation is carried out using vegetable oil and water as fuels, and which has not been represented no scheme of it in the figures, but to describe it here, we make references to some elements of it that can be seen in figures 1, 2, 4, 5, 6, 7, 8 and 9. It mainly includes several aspects to be detailed, and which are described below; when the start-up switch is operated in its first position (heating position), in addition to closing the electrical circuits that supply the electrical energy to the glow plugs (18) and fuel heaters (48) and (65 ), a third electrical circuit is then activated, regulated by a timer clock, which activates an electric fuel priming pump (55), positioned and submerged in the vegetable oil tank (53), and communicating through the ducts (50) and (51) with the accumulator manifold (45) of the vegetable oil injection system (42), allowing said manifold (45) sufficient pressure for [injectors (19) (electrically activated) to through the holes or diffusers (38) of its nozzle (34) they can make one or several simultaneous injections in the different auxiliary pre-combustion chambers (27) and lobes where the minimum time or phase will occur mpression, or these injections are made directly in the aforementioned lobes in case there were no auxiliary pre-combustion chambers (27), all in

the heating time of the glow plug (18), without the need for the starter motor to be operated, and consequently without the high pressure injection pump (43) being operated. A fourth electrical circuit activated simultaneously and in the same way as the third, I will activate the injectors (19), so that they simultaneously inject vegetable oil. the needle (35) that closes and opens the nozzle

(3. 4)

of the injector (19), it will be lifted by electromagnetism, of the existence of this fourth circuit, therefore the electromagnets of the injectors for vegetable oil (19), may be activated by the above-mentioned circuit, as well as when this circuit is deactivated, may be operated by another circuit that governs an electronic unit (56). It will be preferable in the warm-up time, a long time injection (of vegetable oil), quickly activated at the beginning of the heating, than several alternate injections, for this, it will be available in this fourth electrical circuit, of an automatic switch or timer that disconnects said circuit after a certain time, of the electricity supplied by the battery. Said switch may be of any type existing on the market such as watches or timers that can meet the desired requirements. Ace! therefore, when the start-up switch is operated in its second position (starting position), three of the four previous circuits are disconnected, only the glow plug circuit (18) being connected, and in turn connecting others three circuits, one of them governs the synchronized and sequential injection of the injectors for vegetable oil

(19)

through an electronic unit (56), another governs the synchronized and sequential injection of water injectors (20) through another electronic unit (72), and the third circuit will start the starter motor, and with it , the high pressure pumps (43) and (60) (one for vegetable oil and one for water), the drive shaft (12), flywheel, etc., will be operated.

Then, when water is injected into the auxiliary pre-combustion chamber (27) and in the lobe where the maximum compression time or phase will occur, or if appropriate only in said lobe (if there is no auxiliary pre-combustion chamber (27 », the entire The mixture is ignited, burning spontaneously, and thus starting the engine Once the rotary engine of the present invention has been started (1) 6

Chemicals that occur between vegetable oil and water, help and do not hinder combustion.

One of the particularities of the present invention, in the two embodiments

(1) 6 (1a) of the internal combustion rotary engine that is operated using vegetable oil and water as fuels, consisting of two independent fuel tanks, one for vegetable oil (53) and one for water (70).

Another of the particularities of the present invention, in the two embodiments

(1) 6 (la) of the internal combustion rotary engine, that its operation is carried out using as fuel vegetable oil and water, consists of comprising two independent injection systems, one for vegetable oil (42) and one for water (59) .

In the advance to the injection, both of the vegetable oil and of the water, for the two ways of realization (1) and (1a) of the rotary engine of the present invention, of internal combustion of four times, that its operation is carried out using as fuels vegetable oil and water, shared injection well in a pre-combustion auxiliary chamber

(27) and in the lobe corresponding to the compression phase, or direct injection into the lobe corresponding to the compression phase, the necessary time parameters in which the chemical reactions are obtained, as well as the propagation and inflammation time of the total combustion mixture. Since the combustion of the entire mixture is not really done instantaneously, if it does not gradually become inflamed, it is true that it will be done very quickly, but with a minimum delay, to all this. the injection times of vegetable oil and water, governed by the electronic control units (56) and (72) (both connected to their respective probes and sensors, which will determine the position of the motor shaft (12) in a given moment and therefore the position of the rotor (5)} that will provide the advance to advance the injection of vegetable oil in its moment and the advance to advance the injection of water in its moment, so that the combustion of the mixture occurs without delay, and providing that all the combustion expansion force is applied successively and alternately on each of the three faces (6) of the rotor (5). Such advances will be made proportionally to the speed of rotation of the engine, so the aforementioned advances

they will be so much older, the faster the motor of the present invention turns.

Thus, according to the first embodiment (1) of the rotary combustion engine, with shared injection in an auxiliary pre-combustion chamber (27) and in the lobe corresponding to the compression phase, designed so that its operation is carried out using as fuel, vegetable oil and water, it can be defined particularly in its

operation, because its progress to the injection. it consists in that the injection of vegetable oil, is carried out in a shared way in a special auxiliary pre-combustion chamber

(27)

and in the lobe corresponding to the compression phase, in the time of practically minimal compression when one of the faces (6) of the rotor (5) is starting the compression time, and the water injection is performed in said special chamber Pre-combustion auxiliary (27) and in the lobe corresponding to the compression phase or time just before the rotor face (6) is positioned in the maximum compression lobe. Depending on the position of the face (6) of the rotor (5) at the time of the water injection to the advance of the water injection, and also depending on the position of the face (S) of the rotor

(5)

at the time of oil injection, to the advance of vegetable oil injection. These advances being so much greater, the faster the engine rotates. All this regulated by the two electronic control units (56) and (72) of the injection systems (42) and (59) (one for vegetable oil, and the other for water), which through its sensors (57) and (73) of their respective probes, as well as their actuators or activators (58) and (74), will determine the parameters suitable at all times, for advances in injection, both for vegetable oil and for water .

The advance to the injection in the second embodiment (1a) of the rotary internal combustion engine, which is operated using as fuel vegetable oil and water, is analogous to that expressed and defined above for the first embodiment (1), Differentiating exclusively in that in this case the injections, both of vegetable oil and of water, are made directly in the lobe of the engine destined for the compression time, without any auxiliary pre-combustion chamber.
