<p>The present invention is a stratified scavenging two-cycle engine which can make exhaust gas cleaner. For this purpose, in a stratified scavenging two-cycle engine, which includes a scavenging flow passage (3) for connection between a cylinder chamber (4a) and a crank chamber (1a), and an air flow passage (2) connected to the scavenging flow passage (3), and which is constructed so that pressure reduction in the crank chamber (1a) following an upward movement of a piston (7) permits air to be drawn into the scavenging flow passage (3) side from the air flow passage (2), a scavenging port (3a), at which the scavenging flow passage (3) is opened to a cylinder inner surface (4b), is clear of a side wall of the piston (7) and communicates with the crank chamber (1a). <IMAGE></p> |
