Diesel Injector Fuel Injector 0445120079 Bosch for CASE NEW HOLLAND TRACTOR

Injector inspection

If there is no standard fuel injector and tee joint at hand, you can also check and adjust directly on the diesel engine. The specific method is: D remove the high-pressure oil pipe on the diesel engine, install one end of the high-pressure oil pipe on the oil inlet joint of the detected fuel injector, and install the other end on the oil outlet valve joint of the fuel injection pump, and tighten the joint nuts at both ends of the high-pressure oil pipe; 2 Put the throttle handle at the maximum fuel supply position, and when the fuel injection pump is normally supplying fuel, turn the crankshaft so that the diesel engine speed is within 100 ~ 200 r/min, at this time the detected fuel injector sprays fuel to the outside of the cylinder , and observe its atomization; 3 Use a screwdriver (screwdriver) to turn the pressure adjusting screw to make the injection pressure from low to high, and then to make the injection pressure from high to low, repeat this 2~3 times, and select The fuel injector has good atomization quality, no oil beam, clean oil cut-off, and no oil dripping at one position, and the pressure regulating screw can be fixed to continue to use. If during the process of turning the pressure regulating screw, the fuel injector is always poorly atomized, with oil jets, no sound of fuel injection, and oil dripping and oil leakage, it means that the needle valve coupling of the fuel injector cannot be used and should be replaced. Replace with new ones.
