What Are the Reasons for Diesel Engine Failure to Start?
1 Answers
Reasons for diesel engine failure to start: 1. No fuel in the tank or forgetting to open the fuel tank switch; 2. Air or excessive moisture in the fuel supply system; 3. Blockage in the pipeline or filter; 4. Wear of the fuel injection pump plunger; 5. Sticking of the fuel injection pump delivery valve or breakage of the delivery valve spring; 6. Breakage of the fuel injection pump plunger spring, resulting in no pressure in the fuel injection pump; 7. Sticking of the fuel injection pump plunger in the plunger sleeve. The fuel used in diesel engines is diesel, which has higher viscosity than gasoline and is less prone to evaporation, while its auto-ignition temperature is lower than that of gasoline. Therefore, the formation of combustible mixture and the ignition method are different from those of gasoline engines.
