The main reasons why
diesel generator are difficult to start include the following aspects:
1. Fuel system problems:
Insufficient fuel: Check whether the amount of fuel in the tank is sufficient, and add diesel that meets the requirements in time.
Oil circuit blockage: The fuel filter, oil pipe and other parts may be blocked by impurities. Replace the fuel filter regularly and clean the oil circuit.
Injector failure: The injector is blocked or the injection pressure is abnormal, resulting in the inability to inject fuel into the combustion chamber normally, affecting the engine start.
Fuel quality problems: Impurities or moisture in the fuel affect the combustion effect of the fuel.
2. Electrical system problems:
Insufficient battery power: Low battery power may not provide enough power to start the starter motor. Check the battery power and charge or replace the battery in time.
Starter motor failure: The starter motor is damaged or has poor contact, resulting in the inability to start the engine. Repair or replace the starter motor.
Circuit failure: Check whether the circuit connection of the generator is normal, including whether the wires are damaged or the connectors are loose.
3. Compression system problems:
Insufficient cylinder pressure: Piston ring wear, poor valve sealing, etc. cause cylinder pressure to decrease, affecting the compression ratio of the engine, making it difficult to start.
Air filter blockage: A blocked air filter will restrict air from entering the engine, affecting combustion. Clean or replace the air filter regularly.
4. Environmental factors:
Low temperature environment: In cold weather, the viscosity of diesel increases and its fluidity deteriorates, which may cause difficulty in starting. A preheating device can be used to increase the temperature of the engine for easy starting.
High altitude areas: The air is thin and the engine intake volume is reduced, which may affect the starting performance. The engine's intake system can be adjusted to adapt to the high altitude environment.
