Abstract
To provide a four-cycle combustion engine wherein the air-fuel mixture can be smoothly passed at all times by the utilization of the reciprocating motion of the piston to effectively lubricate the valve operating mechanism and the cranking mechanism and also to allow the air-fuel mixture to be supplied into the combustion chamber with a high suction efficiency. By utilization of the reciprocating motion of the piston (), a portion of the air-fuel mixture (M) fed from the intake passage () is circulated through a circulating passage made up of the valve chamber (), the first passage (), the crankcase chamber () and the second passage ().
