我厂生产的295型柴油机,曾严重地出现窜机油(排气系统喷机油)现象。造成窜机油的因素有很多:连杆的扭弯度、曲轴的轴向窜动、活塞环的结构和弹力以及安装是否正确、缸筒与活塞的配合间隙、空气滤清器和油底壳内机油面的高低、配气系统的润滑情况等。我们通过观察和分析认为,在295型柴油机上,窜机油的主要原因是润滑配气机构的油量过大,形成气缸孟上平面油面过高,致使机油通
I plant the production of 295 diesel engines, there has been a serious channeling oil (exhaust system jet oil) phenomenon. There are many factors that cause the channeling of oil: the twisting degree of the connecting rod, the axial movement of the crankshaft, the structure and elasticity of the piston ring and the correct installation, the clearance between the cylinder and the piston, the air cleaner and oil in the oil pan The level of the surface, with lubrication of the gas system and so on. Through observation and analysis, we believe that on the 295 diesel engine, the main reason for channeling oil is that the oil in the lubricating and gas-distributing mechanism is too large to form a cylinder with a flat oil level that is too high,
