摘要： An amount of air taken into an air leading type two-stroke engine is increased to enhance an engine output, and gas emission characteristic deterioration caused by blow-back is inhibited. An inhibition member 16 is disposed between a choke valve 4 in a full open position and a throttle valve 6 in a full open position. The inhibition member 16 includes, for example, a mesh member like a metal mesh. Mixed fuel containing oil is supplied to the air-fuel mixture channel 14. Numerous pores of the inhibition member 16 (mesh member) are occluded by a membrane of oil components of the mixed fuel. Consequently, entry of a blow-back flow of an air-fuel mixture from the air-fuel mixture channel 14 into the air channel 12 through the numerous pores of the flow inhibition member 16 (mesh member) can be inhibited.

摘要： In a two-stroke engine (1) according to the present invention, a piston (6) has a communication passage (28) opened to a crank chamber (10). An air intake port (30) is provided on an inner surface (2a) for causing air to flow into the communication passage (28). After a scavenging port (22) is closed by an outer surface (6a) of the piston (6) moving from the bottom dead center to the top dead center, the communication passage (28) is opened in the outer surface (6a) of the piston so as to communicate with the air intake port (30) and the scavenging port (22).
