    • A stratified scavenging two-cycle engine, in which control of an air flow rate provides a favorable accelerating performance and can prevent deterioration of exhaust gas. The stratified scavenging two-cycle engine comprises a scavenging flow passage (3) for connection between a cylinder chamber (4a) and a crank chamber (1a), an air flow passage (2) connected to the scavenging flow passage (3), air flow rate control means (12) for controlling a flow rate of air fed to the scavenging flow passage (3) from the air flow passage (2), and mixture flow rate control means (11) for controlling a flow rate of mixture sucked into the crank chamber (1a) from a mixture flow passage (10). The air flow rate control means (12) throttles an air flow rate at the time of acceleration. Alternatively, the air flow rate control means (12) is opened later than the mixture flow rate control means (11) at the time of acceleration.
