1. Startup failure:
Unable to start or difficult to start: This may be due to low battery power, starter motor failure, fuel supply issues (such as blocked fuel lines or fuel pump failure), ignition system failure, and other reasons.
Solution: Check the battery level and charge or replace the battery if necessary; Check the fuel pipeline and fuel pump to ensure normal fuel supply; Check the ignition system, repair or replace damaged components.
2. Fuel system malfunction:
Fuel leakage or fuel pump malfunction: causing the fuel system to malfunction.
Solution: Repair or replace the fuel pump to ensure good sealing of the fuel system.
3. Engine overheating:
Reason: Insufficient coolant, clogged radiator, water pump malfunction, excessive impurities and sediment in the cooling system, etc.
Solution: Check the coolant level, clean the radiator, repair or replace the water pump, and keep the cooling system clean.
4. Electrical system malfunction:
Reason: Generator winding failure, excitation system failure, regulator failure, electrical circuit aging or poor contact, etc.
Solution: Check and repair the generator winding, repair or replace the excitation system and regulator, and replace the aging circuit.
5. Insufficient output power:
Reason: Fuel filter blockage, air filter blockage, engine exhaust pressure too high, high oil level, air leakage between the rear end of the engine turbocharger and the intake manifold, etc.
Solution: Regularly replace fuel and air filters, inspect and repair the exhaust system, adjust the oil level, and repair air leaks.
6. Mechanical failure:
Reason: Severe wear of bearings, gears, connecting rods and other components, loose or detached mechanical parts, poor lubrication, etc.
Solution: Regularly inspect and maintain mechanical components to ensure good lubrication, repair or replace worn parts.
7. Other faults:
White smoke, black smoke, abnormal noise: may be caused by low engine cylinder temperature, poor fuel quality, injector failure, etc; Insufficient fuel combustion leads to black smoke emission; Loose, worn, or damaged mechanical components can cause abnormal noise.
Solution: Check and adjust the engine temperature, use high-quality fuel, repair or replace damaged components.
