湿式缸套产生裂纹,这是个可能发生的实际问题。裂纹的产生,就缸套本身而言,涉及铸造质量、尺寸精度以及安装使用等方面,在此不作阐述。本文仅以水冷式柴油机为例,讨论、总结缸套裂纹产生后的判断方法。柴油机缸套产生裂纹的部位和形态具有规律性。裂纹在缸套的内壁位置,处于活塞上止点时第一道气环稍上,对应的外壁位置 Cracking in the wet liner is a real problem that can occur. Crack generation, in terms of the cylinder itself, involves casting quality, dimensional accuracy and installation and use, etc., not elaborated here. This article only water-cooled diesel engine, for example, to discuss and summarize the judgment method after the cylinder liner cracks. Diesel engine cylinder liner cracks and the shape of the site has a regularity. Crack in the cylinder wall position, at the piston top dead center when the first gas ring slightly, the corresponding position of the outer wall
