Description

technical field

[0001] The invention relates to an engine, in particular to a gasoline engine with firm structure and good heat dissipation. Background technique

[0002] The quality of the cylinder structure of the engine is directly related to the quality and life of the engine. The cylinder block of an automobile engine has a cylinder block and a crankcase located below the cylinder block. Multiple cylinder liners are formed in the cylinder block. During the production process, the cast iron cylinder liner is inserted into the aluminum alloy cylinder block to make the cylinder The sleeve and the cylinder block are integrally cast to form a cylinder liner, and a water jacket around the cylinder liner is provided on the periphery of the cylinder liner. Therefore, the side wall of the formed cylinder liner is composed of cast iron and aluminum alloy, but due to the existence of the water jacket , so that the upper part of the side wall of the cylinder liner is separated fro...
