A B S T R A C T The invention relates to internal combustion en- gines of the reciprocal type, and more particularly to such engines in which the pressure for Diesel operation can be attained, or in which the power output of an Otto- cycle engine can be increased. The present invention makes possible either a Diesel engine of approximately the same axial crank offset and overall dimensions as an Otto-engine of equal throughput, or an Otto-engine having a higher throughput with slightly increased overall size and axial crank offset. The said gas supplies are impelled by two pressure impellers which are synchronized to engine operation, a vertical pressure impeller receives a fuel-air mixture and the inverted pressure impeller receives air, a rotary meter- ing pressure booster meters an amount of the fuel-air mixture and forces it under pressure into a pressure retaining cham- ber above the cylinder chamber ready to be released upon demand. A second metering pressure booster supply- ing auxiliary air acts to scavenge and cool the cylinders at the end of each power stroke, as the fuel-air mixture is released from the pressure retaining chamber into cylinder chamber, and as engine speed increases an increasing amount of the auxiliary air will be trapped in the cylinder chamber and compressed together with the fuel-air mixture gradually raising the initial compression as it is compressed into the combustion chamber where it is ignited.
