在柴油机中高压油泵好比人的心脏,它的功能是定时定量地提供高压燃油,通过高压油管及喷油器分配给各个汽缸,在各汽缸内燃烧爆发以推动发动机运转。所以如何正确保养高压油泵,是保证发动机正常运转的关键。 一、注意用油。高压油泵是比较精密的机械总成,它随发动机的运转而高速运转。因此,应及时更换润滑油,以延长高压油泵的使用寿命。一般规定, In diesel engines, a high-pressure pump is like a human heart. Its function is to provide high-pressure fuel regularly and quantitatively, distribute it to each cylinder through high-pressure fuel pipes and injectors, and burn in each cylinder to promote engine operation. Therefore, how to properly maintain the high-pressure oil pump is the key to ensure the normal operation of the engine. First, pay attention to oil. High-pressure pump is a more sophisticated mechanical assembly, which runs at high speed with the engine running. Therefore, the timely replacement of lubricating oil to extend the life of high-pressure pump. General provisions,
