- the invention relates to an engine operating particularly with compressed air or any other gas, and more particularly using a piston stroke control device having the effect of stopping the piston at its top dead center for a period of time as well as an ambient thermal energy recovery device that can operate in mono energy or bi energy.
- variable volume expansion chamber consisting of two separate capacitors, one of which is in communication with the compressed air supply and the other paired with the cylinder and can be placed in communication with each other or isolated so that during the exhaust cycle it is possible to charge compressed air the first of these capacities and then to establish the pressure in the second, at the end of the exhaust then that the piston is stopped at its top dead center and before the resumption of its race, the two capacities remaining in communication and relaxing together to perform the engine time and that at least one of the two capacities is provided with means for modifying their volume to allow equal pressure to vary the resulting torque of the engine.
- the engine according to the invention uses a piston stop device at top dead center. It is preferably supplied with compressed air or any other compressed gas contained in a high-pressure storage tank, through a so-called working capacity buffer capacity.
- the working capacity in bi energy version comprises an air heating device powered by additional energy (fossil or other energy) for increasing the temperature and / or the pressure of the air passing through it.
- the engine according to the invention is characterized by the means used taken as a whole or separately and more particularly: -
- the expansion chamber consists of a variable volume equipped with means for producing a work and that 'it is twinned and in contact by a permanent passage with the space included above the main engine piston, -
- the air or the pressurized gas is admitted into the expansion chamber when it is at its smallest volume and, under the pressure, will increase its volume producing a work
- the expansion chamber is maintained substantially at its maximum volume, the compressed air contained therein then relaxes in the engine cylinder thus pushing the engine piston in its downward stroke by providing a work in turn, -
- the volume varies.
- the expansion chamber is reduced to its smallest volume to begin a complete work cycle.
- the engine expansion chamber according to the invention actively participates in the work.
- the engine according to the invention is called active chamber engine.
- the engine according to the invention is advantageously equipped with a variable-rate expander according to WO 03/089764 A1, known as a dynamic expander, which makes it possible to supply the working capacity at its operating pressure with compressed air coming from the fuel tank. storage by performing a work-free expansion of the isothermal type.
- thermodynamic cycle according to the invention is characterized by an isothermal expansion without work allowed by the dynamic expansion valve followed by a transfer accompanied by a very slight relaxation almost isothermal - for example a capacity of 3,000 cubic centimeters in a capacity of 3050 centimeters cubic - with working by the use of the air pressure included in the working capacity during the filling of the expansion chamber, then a polytropic expansion of the expansion chamber in the engine cylinder with work and lowering of the temperature to end with the escape of the air relaxed to the atmosphere.
- the thermodynamic cycle according to the invention therefore comprises four phases in mono-energy compressed air mode: - Isothermal expansion without work, - Transfer - slight relaxation with work said quasi-isothermal, - Polytropic relaxation with work, - A pressure exhaust room.
- the compressed air contained in the working capacity is heated by additional energy in a thermal heater.
- This arrangement makes it possible to increase the quantity of usable and available energy by the fact that the compressed air before its introduction into the active chamber will increase its temperature and increase pressure and / or volume allowing the increase in performance and or of autonomy.
- the use of a thermal heater has the advantage of being able to use clean continuous combustions that can be catalysed or cleaned up by any known means in order to obtain emissions of minute pollutants.
- the thermal heater can use for energy a fossil fuel such as gasoline gas, or LPG gas CNG, it can use bio fuels or alcohols - ethanol, methanol - to achieve a bi-energy operation with external combustion where a burner will cause a rise in temperature.
- the heater advantageously uses thermochemical processes based on absorption and desorption processes, such as those used and described, for example in patents EP 0 307297 A1 and EP 0 382586 B1, these processes using the evaporation transformation of a fluid for example liquid ammonia gas reacting with salts such as calcium chloride, manganese or other, the system operating as a thermal battery.
- the active chamber motor is equipped with a burner heat heater, or the like, and a thermochemical heater of the aforementioned type that can be used jointly or successively during phase 1 of the thermochemical heater.
- the thermal burner heater will allow to regenerate (phase 2) the thermochemical heater when the latter is empty by heating the reactor during the continued operation of the group with the use of the burner heater.
- the active chamber engine according to the invention is an external combustion engine engine said external combustion engine.
- thermodynamic cycle then comprises five phases: an isothermal expansion, - An increase of the temperature, - A transfer - slight relaxation with quasi-isothermal work, - A polytropic relaxation with work, - An exhaust at ambient pressure.
- any mechanical, hydraulic or other electrical provisions allowing, with respect to the engine cycle, the completion in three phases of the working cycle of the active chamber, namely: during the stopping of the engine piston at its top dead center: a load in the active chamber producing a work by increasing its volume, - during the expansion stroke of the engine piston: maintaining a predetermined volume which is the actual volume of the expansion chamber, - during the exhaust time of the piston engine: repositioning the active chamber to its minimum volume to allow the renewal of the cycle can be used without changing the principle of the invention described.
- variable-volume expansion chamber known as the active chamber consists of a so-called sliding piston sliding in a cylinder and connected by a connecting rod to the crankshaft of the engine, a classic concept which determines a two-phase kinematics: downward stroke and ascending race.
- the engine piston is controlled by a piston stop device at the top dead center which determines a three-phase kinematics: upstroke, stop at top dead center and down stroke.
- the strokes of the load piston and of the engine piston are different, that of the load piston being longer and predetermined so that when in the downward stroke of the load piston, the volume chosen as the "actual expansion chamber volume" is reached, the downward stroke of the engine piston starts and during this downward stroke, the load piston continues and ends its own down stroke - still producing a job - then begins its upward stroke as the shorter and faster racing engine piston catches it in its upstroke so that both pistons reach their top dead spots substantially at the same time.
- the load piston undergoes during the beginning of its upward stroke a negative work which, in fact, has been compensated by a surplus of positive work in the end of its downward stroke.
- the engine according to the invention is driven in torque and in speed, by the control of the pressure in the working capacity, said control being advantageously provided by the dynamic expander, when it operates in dual energy mode with additional energy (fossil or other) an electronic computer controls the amount of additional energy provided, as a function of the pressure in said working capacity
- the active chamber motor according to the invention is coupled to an air compressor for supplying compressed air to the high pressure compressed air storage tank.
- the bi-energy active chamber engine thus equipped normally operates in two modes by using, on a vehicle in town for example, zero pollution operation with compressed air contained in the high pressure storage tank, and on the road, always for the example, in operation additional energy with its thermal heater powered by fossil energy or other, while supplying air through an air compressor the high pressure storage tank.
- the air compressor directly supplies the working capacity.
- the control of the engine is carried out by the pressure control of the compressor and the dynamic expander between the high pressure storage tank and the working capacity remains closed.
- the air compressor supplies either the high pressure reservoir or the working capacity or the two volumes in combination.
- the bi-active active-chamber motor according to the invention actually has three main modes of operation: - mono-energy compressed air, - bi-energy compressed air plus additional energy, - mono energy with additional energy fuel.
- the active chamber engine is also feasible in mono energy with fossil fuel or other when coupled to an air compressor supplying the working capacity as described above, the high pressure compressed air storage tank being then purely and simply deleted. In the case of operation in additional energy mode, with the use of external-external combustion the exhaust of the active chamber engine can be recycled to the intake of the compressor.
- the motor consists of several expansion stages, each stage comprising an active chamber according to the invention; between each stage is positioned a heat exchanger for heating the exhaust air of the preceding stage in the case of a mono-energy operation compressed air and / or an additional energy heating device in the case of operation in bi energy.
