エンジン。 An intake port is formed in the crankcase, which is fixed to the cylinder block and houses the crankshaft, at a position closer to the cylinder block than the axis of the crankshaft, and a check valve that opens and closes this intake port is located in the crankcase. In a two-stroke engine, in which the crank chamber of the crankcase and the combustion chamber are connected through a plurality of scavenging passages, the air-fuel mixture taken in from the intake port is transferred to the inner wall surface of the crankcase near the intake port. A two-stroke engine characterized by having a protruding plate-shaped wall portion that divides air into a side and a scavenging passage.
