Embodiment

[0016] Example: such as figure 1 As shown, a gasoline engine with firm structure and good heat dissipation includes an engine block, a cylinder block 1 is installed in the engine block, a cylinder liner 2 is arranged in the cylinder block 1, and a cylinder liner around the cylinder liner 2 is arranged on the periphery of the cylinder liner 2. The water jacket 3 around 2 is provided with a reinforcing rib 4 of cast iron material between the cylinder liner 2 and the cylinder block 1, and the reinforcing rib 4 is cast integrally with the cylinder block 1 and the outer wall of the cylinder liner 2. The reinforcing ribs 4 are arranged according to the thread structure, and each round of the reinforcing ribs 4 of the thread structure is provided with a gap for antifreeze to pass through.

[0017] A reinforcing rib is arranged between the outer wall of the cylinder liner and the cylinder body, which increases the stability of the cylinder liner and effectively prevents the side wall ...

Abstract

A gasoline engine with a firm structure and good heat dissipation comprises an engine cylinder, wherein an air cylinder is mounted in the engine cylinder, an air cylinder liner is arranged in the air cylinder, a water jacket surrounding the air cylinder liner for a cycle is arranged on the periphery of the air cylinder liner, reinforcing ribs are evenly arranged between the air cylinder liner and the air cylinder, the reinforcing ribs, the air cylinder and the outer side wall of the air cylinder liner are integrally molded through casting, and the thickness of the reinforcing ribs is equal to that of the air cylinder liner. The reinforcing ribs are arranged between the outer side wall of the air cylinder liner and the air cylinder, the stability of the air cylinder liner is improved, and distortion or deformation of the side wall of the air cylinder liner is effectively prevented.

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...
