Beschreibung
Zusammenfassung:	The invention discloses a cylinder sleeve structure which comprises a cylinder sleeve upper portion, a cylinder sleeve lower portion, a supporting step, an O-shaped ring groove and a plurality of scavenging holes. The cylinder sleeve lower portion is arranged below the cylinder sleeve upper portion, and the cylinder sleeve lower portion and the cylinder sleeve upper portion are coaxially arranged. And the supporting step is arranged above the upper part of the cylinder sleeve. And the O-shaped ring groove is arranged between the cylinder sleeve upper part and the cylinder sleeve lower part. The scavenging holes are evenly formed in the lower portion of the air cylinder sleeve and used for engine scavenging. The height of the scavenging holes in the lower portion of the air cylinder sleeve is located at the position of the lower dead center of the piston. Therefore, the cylinder sleeve structure is simple and reasonable in structure, and the requirement for the scavenging amount of a two-stroke engine can be m
