摘要

A stratified scavenging mechanism of a two-stroke internal combustion engine including a carburetor for supplying and controlling an air and fuel mixture to the engine, an air intake passage (2) in which a throttle valve (4) is disposed, an air passage provided on a scavenging air supply body (24), an air control valve (29) disposed in the air passage for opening and closing the air passage, and an air valve lever (32) operably connected to a throttle valve lever (10). The scavenging air supply body (24) is carried by the carburetor. More than one air passage may be provided, and a separate air control valve is preferably provided for each air passage.
