持構造。 The inner diameter of the cylinder is made larger than the inner diameter of the communication port with the cylinder of the crankcase that is fastened to the cylinder, and a stepped portion extending in the circumferential direction is formed on the lower outer surface of the cylinder liner that is shrink-fitted to the inner surface of the cylinder. The stepped portion is engaged with and supported by the end surface of the communication port of the crankcase, and the back surface of the cylinder liner facing the scavenging passage formed in the cylinder is gradually thickened from the end toward the scavenging port side. A liner support structure for a two-stroke engine, characterized by having a sloped surface that looks like this.
