Abstract
PURPOSE: To devise the stabilization at the time of driving at low speeds by leaking part of mixed air from a combustion chamber after an exhaust port has been closed in course of contracting stroke during low speed driving.
CONSTITUTION: In concurrence of forming a mixed air leaking port 36 piercing through the side bulkheads of a cylinder 14 with connecting a mixed air refluent passage 38 to this port 36, said refluent passage 38 makes a combustion chamber 20 conduct with a crankcase 12, and an opening/closing valve 40 is fixed on said refluent passage 38. Said valve 40 is contrived such as to open at the time of idling and low speed driving, and to close at the time of normal driving or output applying driving. This constitution makes it possible to bring it to the same condition as if the contractive ratio may have been brought down in such a way that the contractive pressure had been abated at the time of driving at low speeds or idling, and to improve the stabilization of low speed driving, exhaust emission and drivability
