Abstract

PURPOSE: To fully obtain a scavenging flow amount and good scavenging efficiency, by relatively increasing compression pressure in a crankcase even when partially loaded.
CONSTITUTION: When partially loaded, an air intake throttle valve 201 is reduced to decrease a mixture amount, and if reduced to not less than a certain value, an air bleed throttle valve 15 begins to be opened by an interlocking device 17. A rotary valve 14 in an air bleed device 12 is synchronized with a crankshaft 11, and a cylinder 6 and crank case 4 are communicated by a rotary valve driving gear 16 till a piston 9 of compression stroke closes a scavenging port 5 and air bleed port 13, then an inflammable mixture in the cylinder 6 is bled and partially returned to the crankcase 4.
