Abstract

PURPOSE: To obtain a high power throughout the driving range of a two-cycle engine by mounting a partition with a lead valve in a suction passage.
CONSTITUTION: A valve plate 15 turning with a crankshaft 14 sequentially closes a main suction passage 17a of a suction passage 17 disposed upstream the plate, and an auxiliary suction passage 17b. During a low or middle speed running, a front edge 15a of a valve body 15 is going to approach an end face 2a on the side of the valve plate 15 of a partition 20 so that the partition 20 and a lead valve 22 prevent a mixture pressurized in a crankcase 13 from flowing back from the auxiliary suction passage 17b toward the main suction passage 17.
