Abstract
A two cycle, crankcase compression internal combustion engine which has one or more individually sealed crank chambers defined by one or more crank webs and a transfer passage associated with each chamber formed within the crankshaft body and cylinder block to provide increased flow area for the fuel/air mixture between the induction system and each cylinder. An inner wall forming portion of the crankcase body is expanded outwardly around crank webs and has an inwardly extending member associated with each crank web. A groove is formed in each inwardly extending member and cooperates with each of the outwardly expanding areas to define each of the transfer passages.
