Abstract

The invention discloses a cylinder sleeve with good sealing performance for a gasoline engine. The cylinder sleeve comprises a cylinder sleeve top reinforcing ring, a first outer convex ring, a cylinder sleeve bottom ring opening and a cylinder sleeve body, wherein the cylinder sleeve top reinforcing ring is installed at the top end of the cylinder sleeve body, and a reinforcing structure is installed in the cylinder sleeve body; and the reinforcing structure comprises an inner partition cavity, first reinforcing steel bars, second reinforcing steel bars and reinforcing steel bar blocks. The reinforcing structure is installed in the cylinder sleeve body, the inner partition cavity is formed in the cylinder sleeve body in the using process, the reinforcing steel bar blocks are installed inthe inner partition cavity, the first reinforcing steel bars and the second reinforcing steel bars are connected to the outer walls of the reinforcing steel bar blocks, and the first reinforcing steelbars, the second reinforcing steel bars and the reinforcing steel bar blocks are distributed in a shape like a Chinese character 'mi'. The interior of the inner partition cavity is structurally filled and reinforced, so that the structural strength of the interior of the inner partition cavity is higher, supporting and wrapping are more stable, the quality of the interior in use is better, a bearing is effectively protected, and the service life of the cylinder sleeve is prolonged.

Description

technical field [0001] The invention relates to the technical field of gasoline engine cylinder liners, in particular to a cylinder liner with good sealing performance for gasoline engines. Background technique [0002] The cylinder liner is a steel protective sleeve installed in the cylinder hole inside the gasoline engine for protection. It plays a very critical role in the gasoline engine. Now a gasoline engine with a long service life and a stable internal structure is needed. There are many problems or defects in cylinder liners with good sealing performance but existing cylinder liners with good sealing performance for gasoline engines: [0003] The traditional cylinder liner with good sealing performance for gasoline engine is not strong enough in internal structure, and it is easy to be damaged after long-term use, and the service life of the cylinder liner is not long enough. Contents of the invention [0004] The object of the present invention is to provide a c...
