The injector nozzle is a vital component in the engine fuel system, and the injector nozzle plays a decisive role. In order to ensure the normal operation of the fuel injector, it is necessary to conduct a opening pressure test on the injector nozzle and a needle valve stroke measurement.
Test whether the opening pressure range of the nozzle is within the range specified in the injector maintenance manual (to be verified), if not within the normal range, adjust the nozzle spring to adjust the gasket
If the value is greater than normal, reduce the oil nozzle spring adjusting gasket; if the value is less than normal, increase the oil nozzle spring adjusting gasket.
（2）Stroke Measurement of Nozzle Needle Valve
Use a measuring tool to measure whether the stroke of the nozzle needle valve is within the range (15-45um) specified in the injector maintenance manual. If not, adjust the stroke of the nozzle to adjust the gasket.
If the value is greater than normal, thicken the gasket for oil-nozzle needle valve lift adjustment; if the value is less than normal, reduce the gasket for oil-nozzle needle valve lift adjustment
