PROBLEM TO BE SOLVED: To provide a stratified scavenging double-stroke internal combustion engine having excellent fuel consumption and excellent over-responsiveness at rapid acceleration with clean exhaust gas without lowering the maximum output of the internal combustion engine. SOLUTION: In this stratified scavenging double-stroke internal combustion engine, only air is led into a scavenging passage 7, and the air-fuel mixture is led into a crankcase 18, and when scavenging the internal combustion engine A, the air of the scavenging passage 7 leads the exhaust gas of a combustion chamber 4 for discharge, and thereafter, the air-fuel mixture is supplied to the combustion chamber 4. An air passage 36a for connecting a carburetor C to the internal combustion engine A is formed longer than an air-fuel mixture passage 40. |
