The generator will put out the fire if it catches fire. The reason is that the fuel injection pump piston, which is the housing of the high pressure oil pump, has worn badly over time and will shut down if the pressure is not achieved. When the car is idling at high speed and the engine speed is high, the fire will not be extinguished. At low idle speed, the engine speed is slow, the piston pressure in the fuel injection pump cannot reach the injection pressure, and the fuel injector cannot atomize the diesel, so it stalls.
There are 6 sets of injectors on the engine cylinder head. Due to the high pressure of the new oil pump and piston, the factory pressure is usually adjusted to around 220. But when the engine runs for a long time, the piston pressure will gradually decrease, while the pressure of the injector assembly will stay at around 220. At this point you should selft adjust the injector pressure, or replace the injector piston. It is suggested to take the high pressure fuel pump and fuel injectors to a professional fuel pump expert for calibration.
Other reasons:
1. The extinguisher switch is not turned on and the extinguisher wire is shorted. Lack of oil.
2. Sensor: Disconnect the oil sensor cable and the gasoline engine can start the oil change sensor.
3. Ignition System Problems: Disconnect the spark plug to start and observe the spark. White and red sparks are normal; If there is no spark, replace the spark plug or igniter.
4. Fuel system problems: Check to see if water has entered the fuel. If water has entered, clean the carburetor with gasoline. Determine if the cylinder block is full of fuel, disconnect the spark plug, pressPress the air filter hole firmly with your fingers, start it at idle several times, and smell the fuel smell with your fingers. Determine if the oil supply channel is leaking and change the position of the air damper to see if it can start.
5. Power conversion system and gas delivery system problems: Disconnect the spark plug and press the air filter hole firmly with your fingers. If no compressed gas escapes after idling several times, there is a problem with the power conversion system and gas distribution system.
