SE2000002A1 - Pipe piston (for internal combustion engines) - Google Patents

Abstract

The invention consists of a rotating piston called a pipe piston, (which can be likened to a bicycle wheel, where the hose is the pipe and the spokes are the hub side). which is in the form of a tube which is curved into a circle, sitting in a narrow hub side towards the center of the inner circle, where the hub side is fixedly mounted on an outgoing drive shaft at 90 degrees. The drive shaft is then mounted in each half of an engine block enclosing the pipe piston itself, with piston rings, which rotate in suitable saws between the two screwed engine blocks. When an explosive media is injected into one or more explosion chambers in the engine block and ignites, a pressure wave occurs against the mute engine block. The pressure wave then continues towards the inlet ports in the explosion spaces in the pipe piston that pass and stand in the middle of the explosion chambers. This pressure wave hits a pressure wall in the explosion space which absorbs most of the explosion force, which causes the pipe piston (1) and its outgoing drive shaft to rotate, when explosion then takes place in the various explosion chambers so that the pipe piston continues to rotate controlled by the required power.

Description

Technical area Rork ° lv for internal combustion engines, hereinafter referred to as: Rork ° lv, which replaces conventional, piston, connecting rod and crankshaft. The reciprocating piston rotates mounted in an output drive shaft enclosed in a surrounding engine block. Where the rudder piston is then divided into several explosion compartments, each of which corresponds to the same volume in a conventional cylinder with a piston.

Background There are many different internal combustion engines today and they work very well, but they all have a relatively low efficiency, and other disadvantages, such as imbalances, cial outcome at 16ga speeds and many and moving parts that cause% fuss or tapping problems.

The fiesta engines have a piston which drives a crankshaft via a piston rod. The piston goes c15, up and down. The present invention provides a completely new type of piston, which is fixed and rotates about the drive shaft, which will be explained in more detail in the following.

OBJECT OF THE INVENTION The object of this innovation is to provide an engine which has less vibration, better efficiency and is cheaper to manufacture, although it has variable parts and is easier to regulate, in terms of speed and power obtained. This is also at 15 speed and the reason is as fob er.

Piston engines have been developed during a very Fang period and they have been refined more and more, so that today they are extremely reliable and relatively cheap to produce. The present invention aims to: notwithstanding this, challenge these selectively developed engines, dad & that the inventor thinks that it is behind that a piston should go back and forth with low efficiency and poor power transmission and give imbalances, according to the description below which is taken from Wikipedia.

(Quote from Wikipedia in italics and in quotation marks) "The force experience in a piston engine is only optimal when the crank hose is at 90 degrees, the claw piston engine has a piston that moves linearly and a connecting rod that partially moves in a circular motion The torque therefore becomes positive only during the combustion rate and Orda sinusoidal. and crankshaft. This must be compensated by counterweights which give rise to imbalances which in turn must be compensated in different directions ". None of this is positive for efficiency and economy.

The present invention does not have these disadvantages, as no imbalances occur. The power transmission also always takes place almost optimally towards the output drive shaft.

A piston engine must also have a certain lowest speed, which is called idle speed, it is also the speed that you must achieve to be able to start the engine. The present invention is not dependent on such a minimum speed to be able to start, or to idle.

The in-piston engine will be able to start and idle at very low speeds, so that the compression phase is not needed, nor all the phases present in a conventional piston engine from the time its crankshaft goes to zero in efficiency until it returns to ignition. and goes from the upper zero layer towards the maximum height 90 degrees towards the crank hose. All of the rudder piston's explosion compartments will always explode near the optimal right angle to the outgoing drive shaft, regardless of where an explosion occurs. At a given engine volume, a conventional piston engine will take up about 3 times as much space as the same volume as a rudder piston engine.

This is because more pistons (with their own engine volumes) can fit in the common rotating piston, where no unnecessary spaces are required for each piston connecting rod and crankshaft, as in a conventional piston engine.

The present invention will also be able to run at low speeds and withstand a high load, so that in such cases one can give simultaneous power to all active explosion spaces around the entire circumference of the rudder piston, which means that one is not as dependent on having a high speed , so that the engine does not stop or power. At low loads, the engine can also reduce the number of explosions in the various explosion spaces of the rudder piston, so that the number of ignitions will be very few, which may only, one, or no ignition per vary, or every 3rd 4th or 5th vary, and so on. and then perhaps in just one or a few explosion spaces, which is favorable from an environmental point of view. Unlike a conventional piston engine, the rudder piston can rotate without the aid of continuous ignition, as the piston itself will function as a balanced flywheel with a mass that wants to continue to rotate without the immediate help of new energy.

Opportunity firms and & to quickly and if necessary, be able to activate all explosion spaces to ignite, simultaneously or at the pace that the programming is set to Ora, for different effects and needs. Instead of simultaneously igniting all the explosion spaces, these can be offset in relation to each other so that they do not simultaneously come into ignition mode in relation to the explosion chamber, so that they clamed give a more equalized force and balanced power transmission to the rudder engine.

If a higher speed were to be required, the construction of the invention is such that it could handle very high speeds purely mechanically. It is also possible to tan & different explosion spaces at such a rate that you have time to complete at the stone speed required for explosion and exhaust cycles to catch up with, participate by letting an explosion take place in one and the same explosion chamber once per vary, or twice or alternately vary etc. As required.

Alternatively, shifts are created between the various explosion spaces that exist as far as ignition in them is concerned.

Explosion direction Simplified explanation The rudder piston can be compared to (a bicycle wheel with a duck, which has tucked naysides in the place of spokes and days (Jacket is replaced by a root.), (See figure 1) inside this tube there are several delimited explosion spaces distributed This "wheel" is then mounted inside and between two screwed-together engine block halves, See figure (2) which has a recess to fit the rudder piston which is enclosed and taken by piston rings. they bathe the engine blocks perpendicular to the hub.

Inside the engine block and around the turn-off for the rudder piston are several evenly distributed explosion chambers as well as injection valves and toothed devices which are adapted to the explosion spaces inside the rudder piston. The rudder piston has inlet ports that fit these explosion chambers. Furthermore, in the engine block's turning for the rudder piston, there are oblong overpressure openings in one engine block half, as well as opposite exhaust openings in the other engine block half.

When the rudder piston is then pulled around by a starter motor, explosive media is injected into unseen explosion chambers by means of an industry injection which there gives an overpressure.

Overpressure of oxygen (and if necessary fuel mixture) is then already in the explosion space when this when rotating via an inlet port (8) opens to the explosion chamber where the fuel mixture is further filled and ignited when the inlet port is in the steering wheel 'age. The explosion force then strikes the fixed mute of the engine block in the explosion chamber (which can then be compared to a cylinder head in a conventional piston engine), whereby the force in the stable propagates to the explosion space of the rudder piston. (which can then be likened to the top of a piston in a conventional engine). This force causes the rudder piston and drive shaft to rotate. After the explosion, the explosion space then fills with exhaust gases, which can be evacuated when the rudder piston continues to rotate and overpressure ports in the explosion space then elongate overpressure openings in one half of the engine block. Opposite exhaust ports in the explosion chamber (7) simultaneously open to elongate exhaust openings in the opposite engine block so that the overpressure can now push the exhaust gases out of the explosion space through the exhaust opening and out of the engine block, before the exhaust opening is passed and closed.

The overpressure opening can then be a little longer and therefore remain open a little longer so that an overpressure can build up in the explosion space before the overpressure opening is closed and a new mixer opening (27) then in the stable is in front of the inlet port (9) in the explosion space. be controlled to be injected into the explosion chamber, before the inlet port (8) again reaches an explosion chamber for another cycle of possible injection and ignition after the course set to control injection and explosions in all explosion spaces around the rudder piston, depending on the need for type and type of fuel available, which is controlled by an electronic program with the help of angle sensors on the drive shaft and rudder piston and by the power sensor between the drive shaft and driven wheels.

Some of the advantages of this innovation over the engines used today are that: The invention has fewer moving parts and also the mass that sense in motion during the explosions constantly moves in the same hall, which provides a more efficient operation with much less vibration and wear . The engine block can be made in two halves when the rudder piston is inserted between the two halves in the engine block.

The rudder piston itself can be cast whole or in two halves which are later joined together.

You also get away from all valves that have to go up and down with spring load and power losses.

The number of explosion chambers to be activated is determined by the power required. A single ring piston can in this way contain different numbers of explosion spaces, each of which corresponds to an ordinary piston. On this salt, a ring piston engine could be made very small and very simple, at the same time as it would be without imbalances or vibration problems.

Of course, many ring pistons can be mounted axially along a common drive shaft with Hera screwed together engine blocks. As far as the Oiler size that is possible to manufacture these engines in, it is likely that Ora will have both small and large engines. The common denominator for these engines would be that they have very few movable parts with little space requirements and darldr eager little in relation to engine volume and performance.

At the same time, a ring piston engine would be simple and cheap to manufacture and often vary as needed and very flexible in terms of power take-off at different speeds and be easy to start at very low vary and provide little starting resistance and expected smaller emissions.

Detailed description The rudder piston engine consists of an annular piston. (see figure 1) ddr rudder piston (1) dr, fixed on the drive shaft (2).

The rudder piston (1) can be compared to a tube that is shaped so that it forms a cohesive circle on the same salt as a bicycle hose.

The circular rudder piston (1) is fixed to a drive shaft (2) by means of a hub (3) which in turn is fixed in one or more hub sides hereinafter called the nose side. The nose side (4) is tightly joined to the rudder in the rudder piston (1). glue in the rudder piston (1), evenly distributed, there are a number of explosion spaces (7) which are delimited by a pressure cradle (5) and a guide cradle (6).

Each explosion compartment (7) in the rudder piston has in its periphery three ports fitting to the engine block (11) and an inlet port (8) for the explosive mixture. Furthermore, the exhaust gases pass an overpressure port (9) which is overpressured from an overpressure opening (16) in the engine block (20) to expel the exhaust gases, through the opposite exhaust port (22) to the exhaust opening (15) in the engine block half (19). the engine block (19) in ducts can be evacuated or led to re-injection or purification and further into the air on a conventional sequence description. See figure 3 The rudder piston (1) is shown to have been injected through the overpressure chamber (12) into the explosion chamber (12) with a positive pressure in the explosion chamber (12), which created an overpressure ddr, which was built up during the rudder piston (1) against the overpressure chamber (12). ). When the rudder piston (1) of a starter motor has been forced to rotate.

Explosion occurs via toothed device (14), when the inlet port (8) is completely open towards the explosion chamber (12) in the engine block (11).

The explosion pressure wave then hits the dumb and fixed part of the engine block (11), after which the force in the pressure wave continues into the explosion space (7) where the force then via the control rock (6) reaches the rear pressure wave (5) which is angled and slightly concavely designed so that most of the explosive force will end up against the pressure cradle center (5) (see arrow) (30). ((Delta can be controlled to take place in one or more explosion spaces (7) simultaneously, or offset, or individually)) The pressure carriage causes the rudder piston (1) to rotate at the same time as the drive shaft (2) does so.

The explosion chamber (7) is then filled with exhaust gases (see Figures 2 and 5) Exhaust gases are evacuated when an overpressure port (9) comes in the middle of an elongated overpressure opening (16) in the engine block half (20) where overpressure air is injected in the direction of rotation, while an opposite exhaust port (22) opens to an elongate exhaust port (15) in the engine block (19) through which the exhaust gases in the explosion space (7) can be forced out over time and away by exhaust pipes on conventional salt. The exhaust opening (15), which can be of different lengths, can then close the overpressure opening (16). 27) where suitable mixtures of overpressed fuel, exhaust gases, air, or other media can be injected before the inlet port (8) reaches the explosion chamber again (12) The same process can now take place in several explosion spaces (7) depending on how the automatic tooth The sequence is correct in each case. During this phase, the rudder piston (1) has penetrated the explosion chamber (12), so that new fuel has had time to be injected and build up an overpressure in the explosion chamber (12) when the rudder piston (1) with its inlet port (8) re-stands in the same position as fuel injection (13) and explosion by means of the toothed device (14), which is then controlled by angle sensors on the drive shaft (2) and the rudder piston (1) so that a similar process as previously described can take place, with new cycles in a recurring process.

In the case of direct injection, the fuel mixture is injected directly into the explosion chamber (7) during the time the inlet port (8) is accessible for injection (13). Alternatively, fuel injection can be divided as it also takes place directly into the explosion space (7) via the mixer opening (27).

The shape and size of the inlet port (8) then determines this process depending on the type of industry, etc. It is also possible to create an overpressure of oxygen-saturated Tuft inside the explosion chamber (7) before it reaches the explosion chamber (12). This can be done in two different ways, in that the exhaust opening (15) is slightly shorter than the overpressure opening (16) and is closed before the overpressure opening is closed.

And or via a mixer opening (27) which becomes accessible immediately after the overpressure opening (16) has been passed by the overpressure port (9). Through the mixer opening (27) the overpressure with different mixtures of oxygen fuel, incompletely igniting exhaust gases etc. can be controlled to be injected in a controlled manner so that the explosion space (7) can in this way have a maximum favorable combustion when the inlet port (8) is put back into the injection valve. (13) and the ignition device (14) when an explosion is controlled to ignite only the explosion spaces (7) filled with a fuel mixture.

The overpressure with oxygen and the possibly incompletely igniting exhaust gases will then contribute to the explosions becoming more efficient without this otherwise having a negative effect on efficiency. It is also possible to control the exhaust emissions and the explosions in the explosion space (7) on several salts, for example by passing an explosion space (7) past several overpressure openings (16) without giving fuel and igniting these explosion spaces (7).

The exhaust gases in these explosion spaces (7) then have more time to be evacuated and it is possible to have an overpressure in the explosion space (7) when it is then time to inject fuel and ignite in such an extra evacuated and overpressured explosion space (7) which then will benefit the Combustion1Orloppet. This can be achieved either by constantly creating an overpressure in the explosion space (7) by slightly shifting the overpressure opening (16) versus the exhaust opening (15). an overpressure at the end of such a cycle, 16re it that a combustion in the explosion space (7) is to take place either via the overpressure opening (16) or through a special subsequent opening in the engine block (20) bendmnd mixer opening (27) with special pressure and mixing ayset only for to create an optimal combustion. The overpressure thus created in the explosion space (7) is then maintained where fuel injection takes place, via the injection nozzle (13) which then further increases the overpressure already present in the explosion space (7), until the explosive mixture is fed. to tan & and explode at raft time via the dental device (14).

The overpressure in the explosion chamber (7) and in the explosion chamber (12) simultaneously prevents oil from entering and burning in these spaces.

The rudder piston (1) is swept around against the engine block (11) (see figure 1.) with pair of resilient piston rings (17) which do not completely enclose the rudder piston (1). The piston rings catch each other's joints as they from each side of the nay side (4) enclose each other in their recesses in the rudder piston (1) where they load in their layers in relation to each other radially around the explosion spaces of the rudder piston (1) (7). The nose side (4) is in turn taken by resilient hub rings (18) which are located in recesses in the engine block (11) where they fit into recesses in the nose side (4) on each side.

The engine block (11) dr divided into two halves Vanster half (19) and hoger half (20). In each half (19) and (20) there are turns so that the rudder piston fits exactly between its two halves (19) and (20) when the drive shaft (2) in its support bearings (10) fits into the two halves (19) and (20) when these are then screwed together into a single engine block (11) where the drive shaft (2) is taken with shaft seals on ordinary salt. Several such engine blocks can be screwed together if they share on the same drive shaft and then at the same time share the cooling, exhaust and overpressure ducts, as well as fuel and lubrication ducts and a joint-controlled toothing.

The rudder piston (1) is lubricated through lubrication channels (21) in the engine block (11), where space is also provided for oil sump (25) which can lubricate the constituent movable parts when the rudder piston (1) rotates and then swings around the oil which can then flow back down. in channels (26) to the oil sump (25) after filtration. Oil is prevented from entering the Explosion Chamber (12) and the explosion chamber (7) by the overpressure present there.

Channels for fuel and exhaust gases and connection for ignition Ors on suitable stables with ducts and connections in the engine block (11) Furthermore, cooling ducts in the engine block on suitable stables are adapted for water or other media.

The rudder piston (1) can be cast in one or two halves which are then joined together with finished explosion spaces (7) and with Naysidor (4). The welded two cast halves can then be turned with precision while also recesses for piston rings (17) and other recesses can be made.

The motor block (11) can be made in two halves (19) and (20) the halves can be cast, turned and machined separately and then screwed together with all necessary connections and channels and connections to several interconnected motor blocks (11) with a common drive shaft (2). ) driven by rudder pistons (1) in each interconnected engine block (11) with a common control program for ignition and fuel injection etc.
