Method for operating pollution-free engine expansion chamber and expansion chamber therefor

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.
