分配機構。[Claims for Utility Model Registration] (1) In a crank chamber precompression type two-stroke engine in which the intake passage in the crank chamber wall is opened and closed by a valve plate rotating together with the crankshaft to control the inflow of the air-fuel mixture, Crank chamber precompression characterized in that openings on the crank chamber side of a plurality of scavenging passages rising from the crank chamber and openings on the crank chamber side of the intake passage are communicated by an annular groove provided on the inner surface of the crank chamber. Intake distribution mechanism for a two-stroke engine. (2) The crank chamber is formed in the crankcase, and only the opening on the crank chamber side of the scavenging passage is formed in the crankcase, and the eaves between the top surface of the crankcase and the annular groove widen the top surface of the crankcase for mounting the cylinder. An intake air distribution mechanism for a crank chamber precompression two-stroke engine as claimed in claim 1.
