Abstract
A stratified scavenging two-cycle engine, whose simple configuration can satisfy the regulation of emission rate of THC in exhaust gas, includes: a cylinder block (,), housing a piston (,) so as to be vertically slidable and having an exhaust port (,) and a scavenging port (,) in a sidewall; a scavenging flow passage (,), for connection between a crank chamber (,) and the scavenging port (,); an air supply flow passage (,), connected to the scavenging flow passage (,) and supplying air through a check valve (,); and a mixture supply flow passage (,), for supplying mixture to the crank chamber (,). The supply quantity ratio R=qa/Qf, which is the ratio of a supply quantity qa of air flowing through the air supply flow passage (,) to a supply quantity Qf of mixture flowing through the mixture supply flow passage (,) during a suction stroke in which pressure in the crank chamber (,) is negative, is in the range of 0.7≦R≦1.4.
