Abstract
Object It is intended to prevent intrusion of air-fuel mixture into an air cleaner by blow-back in an air-fuel mixture passage of a stratified-scavenging two-stroke engine. Solution The air cleaner () includes a guide member (). A blow-back flow of air () flowing back to the air cleaner () through a first air opening (A) due to blow-back of air is induced to a vicinity of a second air opening (M) by the guide member (). A blow-back flow of air-fuel mixture () occurring in an air-fuel mixture passage () prior to the blow-back phenomenon in an air passage () collides the air flowmoving toward the vicinity of the second air opening (M), and retains the air-fuel mixture near the second air opening (M).
