Abstract

The invention discloses a cylinder sleeve for a medium speed diesel engine. The cylinder sleeve comprises a cylinder sleeve body assembled in an engine body, wherein the bottom of the cylinder sleeve body is matched with the engine body, the top of the cylinder sleeve body is provided with a water passing sleeve with a flange, the outer wall of the bottom of the water passing sleeve is matched with the engine body, a water cavity is formed between the outer wall of the top of the cylinder sleeve body and the inner wall of the water passing sleeve, the flange of the water passing sleeve is provided with a plurality of water outlets communicated with the water cavity, and a cooling water cavity is formed by the outer wall of the middle of the cylinder sleeve body and the inner wall of the engine body and is communicated with the water cavity. The cylinder sleeve for the medium speed diesel engine is simple in structure and reasonable in design, and the cooling water cavity has a bigger water containing space, so that a better cooling effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of diesel engines, in particular to a cylinder liner used for diesel engines. Background technique [0002] The cylinder liner is one of the most important parts of the engine. Its main function is to form the combustion chamber of the engine together with the cylinder head and the piston. The inner surface of the cylinder liner is directly affected by the high temperature and high pressure gas and the lateral force of the reciprocating piston. The working environment is very bad. With the advancement of technology, the degree of strengthening of diesel engines is gradually increasing, and the temperature and pressure in the cylinder are also gradually increasing. These changes will inevitably increase the thermal load of the engine, resulting in higher temperatures of the cylinder head and cylinder liner, deterioration of lubrication conditions, and increased cylinder wear. Excessive fuel consumption. [...
