Hello! The main reasons for misfires: 1. Engine ignition timing is incorrect, too early or too late. 2. The fuel supply line is blocked and fuel cannot enter the cylinder. 3. The oil pipeline is loose or damaged and there is some air in the oil pipeline. 4. Fuel label does not match engine label. Bad quality. 5. The engine intake and exhaust valves are not closed tightly or the valve clearance is too large or too small. 6. The fuel injection nozzle is clogged or the fuel injection pressure is not standard.
What should I do if the gasoline generator does not catch fire?
When the generator catches fire, it puts out the fire. The reason is that the fuel injection pump piston, which is the high pressure oil pump housing, has worn badly over time and will shut down if the pressure is not increased.s reached. 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 either 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.
Autres 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 condition of 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 whether the cylinder block is full of fuel, disconnect the spark plug, press 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 pto see if it can start.
5. Power conversion system and gas distribution 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.

First check whether the engine oil and gasoline are newly added. Otherwise, they have been added more than three months ago as well as the engine oil. must be removed. Drain and replace gasoline. Engine oil and gasoline are only valid for three months. Oil and gasoline used for more than three months have lost their viscosity and are useless.
Check if the engine oil and generator gasoline are filled. Otherwise, the generator will not be able to turn on and start.
If the above is achievedt, check if the spark plug lights. Otherwise, remove the spark plug, dip some gasoline in it and install it to see if the generator fires. Get up and everything is fine.
Detailed information:
When using a gasoline generator, please note:
1) Theory guides practice. Only by thoroughly mastering the basic principles and basic structure of small gasoline engines can we carry out fault analysis and treatment, especially for different types of oil engines, specific model analysis specific is required;
2) When an error occurs. Only by carrying out comprehensive and scientific analysis and judgment based on the scene can we guarantee that the fault is handled accurately, and we cannot handle the problem based on imagination or guesswork. so-called past experience. Gasoline engines haveoften oil lines, circuits and other parts fail at the same time, resulting in more complex failure phenomena. Sometimes similar phenomena occur at different fault points, causing certain troubleshooting difficulties.
By connecting and analyzing fault phenomena observed on site, imagining different possible causes of the fault and analyzing and comparing them, the extent and location of the fault can be determined. Then from simple to complex, from the outside to the inside, first analyze the circuit then the oil circuit, then calibrate the ignition time, check the order of gas distribution, and compress the fault until 'at a certain point
3) Develop good habits, carry out necessary inspections before starting the machine and carry out regular inspections during machine operation to try to avoid sudden breakdowns
4) Strictly carry out technical maintenance; all levels on the oil machine to ensure that the oil is in good working condition to avoid sudden breakdowns and major accidents.
