When it is found that the diesel generator set has problems such as start-up difficulty, low work efficiency, increased fuel consumption, unstable speed, black exhaust smoke, knocking sound, etc., most of them are caused by the poor fuel injection quality of the unit. How to judge and solve the problem of poor fuel injection quality of diesel generator sets?
1. The cylinder breaking method is used during the operation of the diesel engine (the plunger spring of a cylinder is jacked up with a screwdriver). If a cylinder stops supplying oil, the machine runs without any change, but the black smoke is reduced, that is the cylinder. The injection quality is not good.
2. The fuel injector of the cylinder should be removed and repaired.
3. After removing the fuel injector, connect it to the high-pressure fuel pipe of the fuel injection pump of the diesel generator set, remove the side cover of the fuel injection pump, use a screwdriver to pry the plunger spring seat to perform pumping action, and check the fuel injection pump. The fuel injection condition of the nozzle. If the quality of the fuel injection is still not good, the fuel injector should be disassembled for inspection and adjustment. When disassembling, the existing house should be soaked in gasoline and then disassembled, and then placed on a wooden block to grind away the carbon deposits.
4. Excessively worn fuel injectors should be replaced in time.
