To provide a stratified scavenging two-cycle engine capable of smoothly shifting to sudden acceleration from idling, while being a simple structure.
A two-cycle engine for introducing air-fuel mixture (M) and air (A) to a combustion chamber (1a) from scavenge air passages (30, 31) includes: valve bodies (50, 51) that adjust openings of an air passage (23) for supplying the air (A) to the scavenge air passages (30, 31) and an air-fuel mixture passage (24) for supplying the air-fuel mixture (M) to the scavenge air passages (30, 31); a check valve (41) that prevents back flow of the air (A) in the air passage (23); and delay members (60, 63) that project to the air passage (23) upstream of the check valve (41) and delay the time when the air (A) reaches the scavenge air passages (30, 31) from the valve body (50).
