Abstract

Stepped piston has a first portion working in the conventional way as the movable wall of the combustion chamber. A stepped, or enlarged dia., portion operates in an adjacent, axially aligned, bore of the cylinder. The stepped portion of the piston is ported and check valves are provided at the ports which permit a one way flow of fuel-air mixture from the engine crankcase into the compressor portion of the engine comprising the stepped portion of the piston and the bore in which it is working. This arrangement provides two intake and two compression strokes of the compressor per four cycle combustion cycle. The mixture which enters the compressor on the down-stroke of the piston is trapped by the check valves, compressed on the up stroke and delivered into a bypass and accumulator manifold connected to the intake valve for the main cylinder.
