DEFINITION
Classification: 123/318
Rear compression of air or combustible mixture to be subsequently pumped into the working cylinder:
(under subclass 311) Subject matter wherein the charge or some part of the charge is compressed by the engine working piston on its downstroke in a volume other than that of the engine crankcase.
