Abstract:
Method of operation of an engine comprising an expansion chamber, an induction and compression chamber (1) and an expansion and exhaust chamber (4) which are independent, with the injection of an additional compressed non-polluting gas into the expansion chamber (2) in which a process of pressure increase occurs, characterized in that it consists in splitting the process of increasing the pressure in the expansion chamber into two stages, by introducing, on the one hand, a high-pressure driving gas from the induction and compression chamber into part of the expansion chamber and by introducing non-polluting so-called â€œworking gasâ€  on the other hand, the additional compressed into the other part of the expansion chamber at a pressure markedly lower than the pressure obtaining in the first part, then in suddenly bringing the two parts into contact to obtain, because of the pressure difference, a sudden expansion of the driving gas which expands in the form of an expansion wave and flows into the working gas, thereby creating a compression shock wave which makes it possible to considerably increase the total pressure in the expansion chamber shortly before it expands in the expansion and exhaust chamber to produce work.
