柴油机气缸盖上的喷油器安装孔除了用于安装喷油器外,还有以下用途: 1.注油 当发现由于气缸密封不良,造成起动困难时,可以从喷油器安装孔注入少量清洁机油,并摇转曲轴数次,使机油均匀地填满活塞与缸壁之间的间隙。多缸柴油机进行以上操作时,应逐缸拆下喷油器分别注油,不能图省事,向进气管注机油。否则当某一气缸处于吸气行程时,会吸入过多机油而形成“油垫”,可能发
The injector mounting holes on the cylinder head of the diesel engine are used for the following purposes in addition to installing the fuel injector: 1. Filling When a difficult start-up is found due to poor cylinder sealing, a small amount of cleaning oil can be injected from the injector mounting hole , And crank the crankshaft several times so that the oil fills the gap between the piston and the cylinder wall evenly. Multi-cylinder diesel engine for the above operation, should be removed by cylinder fuel injector, respectively, can not figure things to note the intake pipe oil. Otherwise, when a cylinder is in the suction stroke, it will inhale too much oil to form an “oil pad”
