1．添加润滑油不可过量若柴油机的油底壳、调速器、空气滤清器的机油平面超标,滚动轴承添加过量的润滑脂,均会诱发故障甚至使发动机损坏。例如,当油底壳内机油平面超标时,虽然有助于改善气缸的润滑,但通过活塞环泵入燃烧室的机油增多,不仅增大了油料消耗,还会在活塞、气门和喷油喷处形成积炭,从而造成气门漏气、喷油器雾化不良、压缩比提高和气缸内局部过热。对汽油机,还会诱发表面点火和出现爆震燃烧。严重时,多余机油参加燃烧会使发动机超速甚至飞车。
1. Add excessive oil If the diesel engine oil pan, governor, air filter oil level exceeded, rolling bearings add excessive grease, will cause failure or even damage to the engine. For example, excessive oil levels in the oil sump, while helping to improve cylinder lubrication, increase the amount of oil pumped into the combustion chamber through the piston rings, increasing fuel consumption and reducing oil consumption in pistons, valves, and injection spouts At the formation of coke, resulting in valve leakage, poor atomizer injector, the compression ratio increased and the cylinder overheating. On the gasoline engine, but also induced surface ignition and knocking combustion. Seriously, the extra oil to participate in the combustion will make the engine speed or even speed.
