What's wrong with the Perkins diesel generator not catching fire

Sometimes in the use of diesel generators, usually obviously very pay attention to maintenance and repair, but diesel generators will still appear a variety of failures, for example, in the start of diesel generators will not fire problems, but also because of non-professional personnel, may also take a lot of time to repair, so what is the cause of the generator can not fire? How should we do maintenance at ordinary times?

1. Cause of failure

There is leakage in the intake system; Fuel pressure is too low; The air filter is blocked; Water temperature sensor failure; Air flowmeter failure; Idle control valve or additional air valve failure; Cold start injector does not work; Fuel injector oil leakage; Incorrect ignition timing; The connection between the start switch and the computer is disconnected; The cylinder compression pressure is too low.

2. Fault diagnosis and troubleshooting

1) Fault self-diagnosis. If there is a fault code, find the corresponding fault cause according to the fault code.

2) Check the vacuum degree of the intake pipe at idle speed. If the vacuum is less than 667kPa, it indicates that there is air leakage in the intake system. Check the joints, gaskets, vacuum hoses of the intake pipe, as well as the exhaust gas recirculation system and fuel evaporation recovery system.

3) Check the air filter. If the filter element is blocked, it should be cleaned or replaced.

4) If the engine can start normally when the throttle is about 1/4 open, but it is difficult to start when the throttle is fully closed, it should check whether the idle control valve and additional air valve work normally. In idling operation of cold car, unplug the wiring harness of idle control valve, or in idling operation of cold car, the additional air valve air hose is clamped with pliers, if the engine speed does not decrease, it indicates that the idle control valve is not working properly, should check the idle control valve and its control circuit.

Diesel generator maintenance

1. Check the working report of diesel generator.

2, check the diesel generator: oil plane, coolant plane.

3. Daily check whether the diesel generator is damaged, adulterated, and whether the belt is slack or worn.

4, check the air filter, clean or replace the air filter core.

5. Release water or sediment in the fuel tank and fuel filter.
