Diagnosis Methods of Common Faults of Diesel Engines

1. The method of diagnosing whether the outlet valve of the fuel injection pump and the fuel injector are sealed

(1) When diagnosing whether the oil outlet valve of the fuel injection pump is sealed, place the fuel supply control rack in the stop oil supply position, and remove the high-pressure fuel pipe from the fuel injection pump, then pump the oil with the hand fuel pump, and observe whether there is diesel oil flowing out of each fuel pipe joint. If diesel oil flows out, it indicates that the outlet valve is not well sealed, or the spring of the outlet valve is broken.

(2) The method of diagnosing whether the fuel injector is sealed is to put the end of the high-pressure fuel pipe removed from the fuel injection pump into a cup filled with diesel oil, start the engine and let it run idly, and observe whether there are air bubbles in the fuel pipe from the fuel cup. emerge. If bubbles come out, it means that the injector is not sealed. If conditions permit, the fuel injector can be removed, and its tightness can be checked with a fuel injection pressure tester.
