在高速内燃机上,气缸套承受着仅次于气缸盖和活塞的热负荷,它与活塞环一起密封高温高压燃气。气缸套外壁与机体组成冷却水腔,是帮助活塞散热的重要部件。因此,发动机的性能和寿命主要取决于气缸套等一些重要零部件的质量和结构型式。换言之,气缸套设计与制造水平的优劣,对于提 On high-speed internal combustion engines, the cylinder liner withstands the thermal load second only to the cylinder head and piston, which seals the high-temperature and high-pressure gas together with the piston ring. Cylinder liner wall and the body composition of the cooling water chamber, is an important part of the piston to help heat. Therefore, the performance and life of the engine mainly depends on the quality and structure of some important parts such as cylinder liner. In other words, the design and manufacture of cylinder liner pros and cons, for the mention
