Abstract
A stratified scavenging two-cycle engine is capable of doing away with emission of a mixture into the atmosphere and of reducing intake resistance of air. For this purpose, an air intake port (11) is provided at a position which is a predetermined distance away from scavenging ports (51) toward a crank chamber (20) parallel to the axial direction of the cylinder block (1), and the scavenging ports (51) are connected to the air intake port (11) through a piston (3) to thereby supply air to scavenging flow passages (50) from the air intake port (11) through the scavenging ports (51) at the time of an intake stroke.
