Abstract
Abstract The invention relates to internal combustion engines 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. Gas supply pressures are maintained in pressure boosters by two pressure impellers which are synchronized to engine operation, a vertical pressure impeller receiving a fuel-air mixture and the inverted pressure impeller receiving air. A rotary metering pressure booster meters an amount of the fuel-air mixture and forces it under pressure into a pressure retaining chamber above the cylinder chamber ready to be released upon demand. A second rotary metering pressure booster supplying 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.
