1.喷油器的检修 喷油器的针阀偶件在长期的工作中,由于受到高压油的冲刷、机械杂质的研磨和压力弹簧的落座等联合作用,会使针阀和阀体的配合表面受到磨损,从而引起喷油前的泄漏和断油后的滴油现象,造成雾化不良、燃烧不完全、炭烟剧烈增加、积炭严重。所以,对喷油器必须进行定期维护。
1. Injector Maintenance Injector needle valve coupler In the long-term work, due to the erosion of high-pressure oil, grinding of mechanical impurities and the pressure spring seating and other joint action, will make the needle and valve body with The surface is subject to wear and tear, causing leakage before fuel injection and oil dripping after the phenomenon of oil, resulting in poor atomization, incomplete combustion, carbon stench increased drastically coke. Therefore, the injector must be regularly maintained.
