Diagnosis Methods of Common Faults of Diesel Engines

1. Method of diagnosing blockage of diesel pipeline

When diagnosing whether the diesel pipeline is blocked, loosen the bleed screw plug on the fuel injection pump, then pump oil with the oil pump by hand, and observe the oil flow at the bleed screw plug. If the diesel oil is sprayed out with the pressure of the hand oil pump, it indicates that the oil circuit is smooth; if the oil flow is not smooth, and the pressure of the hand oil pump is very resistant (very laborious), it indicates that the oil circuit is blocked or the diesel filter is too dirty.

2. Diagnosis method for poor operation of fuel pump

Diagnose whether the oil pump is working normally, it should be carried out when the oil circuit is unblocked and sealed without air. The diagnosis method is as follows: Loosen the bleed plug, start the engine and make it idle, and observe the oil output at the bleed plug. If the diesel oil is sprayed out, it means that the fuel pump is working normally; if the fuel is not injected or the fuel injection is not smooth, it means that the fuel pump is not working or is not working properly.
