Injector is a high-precision machining of precision components, the higher the dynamic flow range, anti-clogging performance requirements, so it is more important for the maintenance of the injector, so let's understand the next injector maintenance work:

Injector work around 700h should check the adjustment again. If the opening pressure is lower than the predetermined value 1Mpa more serious head or needle coke serious, should be discharged into the needle with clean diesel soot scraped wood, with a thin wire to clear the nozzle, installed after commissioning, It requires the same variety of economic steam cylinder injection pressure differential must be less than 1Mpa.

In order to make the injector is injected into the cylinder for complete combustion of diesel in a timely manner, the pump must be checked regularly supply time. Oil too early, there will be difficulty in starting the vehicle and knock failure, oil too late will lead to black smoke exhaust, machine temperature is too high, increased fuel consumption.

With high precision dual injector needle member and the spray-hole diameter is small, and therefore must be strictly in accordance with the provisions of selected seasonal changes take good clean diesel, or the fuel injector will not work.

When cleaning the injector needle Couples not with other hard objects collide, it also can not fall to the ground, so as not to bruise bruises. When replacing the injector needle Couples should first coupling member into the hot new diesel 80 ℃ soak for about 10s, anti-rust oil to make fully melted, then a clean diesel will needle valve in the valve body back and forth tic, wash thoroughly, so as to avoid anti-rust oil melted and stick the needle valve failure occurs when fuel work.
