1. Difficulty or inability to start:
Reason: Fuel system issues (such as empty fuel tank, clogged fuel filter, air in fuel lines), low battery power or corroded battery terminals, starter motor failure, etc.
Solution: Check and ensure that the fuel tank is full, replace the clogged fuel filter, remove air from the fuel system, charge or replace the battery, and test the starter motor.
2. Sudden shutdown during operation:
Reason: Fuel depletion, coolant overheating, overload protection triggering, electrical faults (such as generator winding short circuit, excitation system failure) or mechanical faults (such as bearing damage, connecting rod fracture).
Solution: Check the fuel supply, ensure the cooling system is working properly, and eliminate electrical and mechanical faults.
3. Insufficient power output:
Reason: Empty fuel tank, broken governor spring, clogged fuel filter, insufficient fuel injection from pump, poor fuel quality, and clogged cooling system.
Solution: Check and replace the fuel filter to ensure sufficient fuel supply, and adjust the governor parameters.
4. Abnormal emissions:
Black smoke: may be due to turbocharger failure, poor sealing of valve components, or precision component failure of fuel injectors or high-pressure oil pumps.
Blue smoke: It may be due to worn piston liner or improper lubricating oil grade.
White smoke: It may be a problem caused by the presence of water in the fuel or prolonged use of the engine.
Solution: Check and replace damaged components to ensure proper use of lubricating oil and fuel.
5. Cooling system issues:
Reason: Water pump failure, radiator blockage, coolant leakage, etc.
Solution: Check and repair all components of the cooling system to ensure sufficient coolant and no leaks.
6. Unstable voltage:
Reason: Voltage regulation device malfunction, aging and damaged accessories, power supply issues, operational problems.
Solution: Check and repair the voltage regulation device, regularly maintain the components inside the generator set, and ensure stable power supply.
7. Wear and tear of mechanical components:
Reason: Long term operation causes wear and tear on components such as crankshafts, connecting rods, and bearings.
Solution: Regularly inspect and replace worn mechanical components, and make precise adjustments.
8. Overspeed or overload operation:
Reason: Excessive load can easily cause mechanical components to bear thermal and mechanical loads under high-speed working conditions.
Solution: Avoid overloading operation, allocate loads reasonably, and regularly check the wear of mechanical components.
