(1)呼吸器的作用柴油机活塞环与汽缸壁之间有一定间隙,柴油机运转时,会有少量高温高压气体从燃烧室经此间隙进入曲轴箱,致使曲轴箱内的压力升高。随着柴油机持续运转,润滑油不断将高温部件的热量带回油底壳,使油底壳温度不断升高。在高温作用下,润滑油中的轻质易挥发成分会不断挥发出来,进一步增加
(1) The role of respirator There is a certain gap between the piston ring of the diesel engine and the cylinder wall. When the diesel engine runs, a small amount of high temperature and pressure gas will enter the crankcase through the gap from the combustion chamber, causing the pressure in the crankcase to rise. With the continuous operation of the diesel engine, the lubricating oil continuously returns the heat of the hot components to the oil pan, causing the temperature of the oil pan to increase continuously. Under the action of high temperature, the light volatile components in the lubricating oil will continue to evaporate, and further increase
