Abstract

An improved internal combustion engine which utilizes a compressed air source (30) to supply high pressure air into the combustion chamber (13) of the engine through a high pressure air injection valve (28). Subsequent to detonation, the exhaust valve of the cylinder opens to allow the spent fuel contained within the combustion chamber to escape therefrom. By flushing the combustion chamber with compressed air, the high pressure air injection valve accelerates the speed and efficiency of removal of exhausted fuel from said combustion chamber, and hence increases the efficiency of the next cycle of combustion since the newly intaken fresh fuel supply which is introduced into the combustion chamber may burn cleanly upon detonation without contamination from remaining combusted fuels.
