Internal combustion engine with stepped piston supercharger
Patent
·
OSTI ID:5713547
A reciprocating piston four cycle internal combustion engine utilizes a stepped piston the stepped portion of which, working in an enlarged bore in the block, serves as a compressor to provide a supercharged fuel-air mixture to the combustion chamber. The compressor delivers two compression strokes per engine cycle. The compressed fuel-air mixture travels from the compressor via a bypass manifold, which also serves as an accumulator, to the main cylinder via an intake valve. Fuel-air mixture is admitted to the compressor cylinder through the crankcase and valved passages through the stepped portion of the piston.
