Abstract: The invention concerns a cogeneration plant preferably using a compressor-alternator unit equipped with a thermal heater operating independently, by drawing compressed air supplied by one or several compression stages, which is then heated to increase its temperature and/or its pressure, then re-injected into the expansion chambers of the engine to produce the power stroke, wherein the home heating is used as device for heating the compressed air and usable in a local network where each house of a housing group (40, 40A,) is equipped with such units, interconnected (41) and controlled by a power management station (42) for the supply of electric power to each of the houses from one or more units capable of being activated successively and/or alternately depending on the overall requirements of the houses of the network.

Abstract: Motor-driven compressor-alternator unit including pistons. Each piston has a large diameter portion and a smaller diameter portion extending from the large diameter portion. The large diameter portion slides within a first cylinder and provides a motor function. The smaller diameter portion slides within a second cylinder and provides a compressor function. An arrangement at least one of inactivates the motor function during compressor operation, inactivates the compressor function during motor operation, and activates ambient heat recovery during motor operation. This Abstract is not intended to define the invention disclosed in the specification, nor intended to limit the scope of the invention in any way.

Abstract: A method and device for reaccelerating a vehicle equipped with a compressor supplying high-pressure compressed air for cleansed or cleansing engine is provided, in which, during decelerating and/or braking phases, the on-board compressor being operated, the high pressure compressed air flow is derived and stored in a reaccelerating reservoir, thermally insulated and maintained at very high pressure and very high temperature, to be used when the vehicle is put back in driving phase by being injected at high temperature and at high pressure in the combustion chamber of the engine.

Abstract: The invention concerns a method for operating a pollution-free engine chamber by injecting supplementary compressed air, comprising a suction and compression chamber (1) and an expansion and exhaust chamber (4) independent of each other, which consists in separating the pressure increase process in said expansion chamber by dividing it into the two chambers, an engine chamber (2A) which receives high pressure air and a working chamber (2B) which receives the supplementary compressed air with lower pressure, separated by a quick-operating plug (2c) which communicates them suddenly thereby causing, owing to difference in pressure levels, a wave expanding the engine gas which flows into the working chamber generating a compressive shock wave substantially increasing the pressure level in the chamber shortly before it is communicated with the expansion and exhaust cylinder (4) to produce a work.

Abstract: The invention concerns an auxiliary power unit using compressed air for energy and equipped with a motor alternator driving, or being driven by a motor compressor with compressed air which compresses air under high pressure in a high pressure storage tank and which when there is a power cut automatically drives the motor compressor in alternating mode to supply electricity. The invention is applicable to fixed or mobile auxiliary power units.

Abstract: A method for reducing pollution in a mono-mode air-air combustion engine having an intake and compression chamber, connected to a constant volume expansion chamber, which is connected in turn to an expansion and exhaust chamber. External air is drawn into the intake chamber and compressed to an increased pressure and temperature. The compressed air is transferred to the constant volume expansion chamber, wherein additional, ambient temperature, compressed air is injected therein. The injected air, when contacting the elevated pressure and temperature of the compressed air causes an expansion of the air within the constant volume expansion chamber. The energy associated with the air expansion is transferred to the expansion and exhaust chamber, wherein the continued compressed air expansion produces a work force that is imparted to a piston. The energy depleted air is then exhausted through an exhaust value.

Abstract: The invention concerns a method for additional thermal heating for motor vehicle equipped with pollution-free engine operating with additional compressed air injection into the combustion chamber (2) and having high pressure compressed air storage reservoir (23). The high pressure compressed air contained in the reservoir is previously to its final use at a lower pressure, directed towards a thermal heater (56) to increase its pressure and/or volume before it is injected into the combustion or expension chamber (2). The invention is applicable to all engines equipped with compressed air injection.

Abstract: A pollution control method and related devices for cyclical internal combustion engines having a separate combustion chamber (1), wherein the compression chamber, the combustion chamber (1) and the expansion chamber (16) consist of three separate and entirely self-contained portions. During low-power operation, e.g. in urban traffic, the fuel injector (6) is no longer controlled during filling of the combustion chamber, whereby the combustion chamber is filled with high-temperature pure compressed air at each cycle. A small amount of additional air from an outer tank (23) for storing highly pressurized air at room temperature is fed into the combustion chamber substantially after the intake of compressed air from the engine compressor, and heated as it contacts the hot compressed air already present in the combustion chamber (1), whereafter it expands and increases the starting pressure to enable effective work to be produced during expansion.
