    1. When the diesel generator set is automatically turned off, the speed gradually decreases, the operation is unstable, and the exhaust emits white smoke, which indicates that there is water in the diesel, the cylinder gasket is washed out, or the automatic decompression is damaged. Measures: Replace the cylinder gasket and adjust the pressure reducing mechanism.

    2. The exhaust pipe emits black smoke and the gas throttle cannot work normally, which is mostly caused by poor diesel combustion in the diesel generator, the main reason is that the air filter and the intake tract are seriously blocked by impurities, resulting in insufficient air intake, the air filter should be cleaned, the intake pipe should be dredged to ensure sufficient air.

    3. When the automatic flame-off, the operation is continuous and unstable, accompanied by abnormal knocking sound, this phenomenon is a sudden mechanical failure, and the common reasons are: crankshaft breakage, piston pin breakage, connecting rod bolt loosening or breaking, valve lock plate, valve circlip falling off, valve spring breaking or valve stem breaking, resulting in valve falling off, etc. Once the generator is found to be in this situation during the work, it should be stopped immediately for inspection to avoid major mechanical accidents, and can be sent to a professional maintenance point for a comprehensive inspection.

    4. When the engine is automatically turned off, the speed is suddenly reduced, and the exhaust pipe is seriously emitted black smoke, which is mostly caused by the sudden and strong obstruction of the engine operation, and the reasons are: lack of water in the cooling system, overheating of the engine, resulting in the piston being strained in the cylinder liner, stuck, poor lubrication of the friction pair, and the burning tile holding shaft or the parts of the valve mechanism are bitten, etc., so that the engine is suffocated. The maintenance of the lubrication system and cooling system should be strengthened, and sufficient lubricating oil and cooling water should be added.

    5. When the engine is automatically turned off, the sound of the diesel engine is muffled, the operation is difficult, and black smoke is emitted. This indicates that the diesel engine is overloaded.

    6. There is no abnormality before automatic flame-out, and the flame is suddenly extinguished, which indicates that the fuel injection pump or fuel injector suddenly stops supplying oil. The reasons are: the plunger spring is broken, the plunger is stuck by impurities, the injector needle valve is stuck, the compression spring is broken, the fuel injection pump control lever and its connecting pin fall off, the fixing bolt of the fuel injection pump drive shaft and the driving disc is loosened, the key on the shaft is cut flat due to looseness, resulting in the sliding of the drive shaft or the driving disk, so that the drive shaft can not drive the fuel injection pump to work, etc.

    7. When automatic flame-off occurs, the speed gradually decreases, and there is no abnormal phenomenon in the running sound of the diesel engine and the exhaust smoke. This shows that the horizontal bar diesel engine should not be used, because the diesel in the fuel tank is used up, or the fuel tank switch is open, or the fuel tank vent, fuel filter and fuel pump are blocked, or the oil circuit is not sealed into the air, resulting in "air resistance" (accompanied by unstable speed before the flameout) Measures: The low-pressure oil circuit should be checked, first check whether the fuel tank, fuel tank switch, filter, and fuel pump are short of oil, blocked or the switch is not opened, etc., and then loosen the air release screw on the fuel injection pump, and press the fuel pump button. Observe the oil flow at the vent screw, if there is no oil outflow, the oil circuit is blocked, if there are bubbles in the flowing oil, it is the air entering the oil circuit, which should be checked and eliminated section by section.

    Of course, the operation of the gasoline engine requires the ignition of the spark plug to ignite the combustible mixture, and the electricity of the spark plug uses the electricity generated by the generator in the case of generator power generation, if the generator does not generate electricity, it can only use the electricity of the battery, but the electricity in the battery can not support it for a long time.

    The power supply of gasoline vehicles is mainly powered by batteries and generators, such as ignition, fuel injection, meters, heaters, radios, etc.

    When the generator does not generate electricity, it starts to use the electricity from the battery, and when the battery is depleted, the car will of course turn off.

    The generator does not generate electricity, and the battery electricity is consumed. The gasoline engine cylinder needs to be ignited with electricity, so it needs electricity to work all the time while driving. If the generator does not generate electricity, the battery alone will not last long, and when the voltage drops below nine volts, it will turn off.

    The car generator is the main power source of the car, and its function is to supply power to all electrical equipment (except the starter) when the engine is running normally, and at the same time charge the battery.

    On the basis of the three-phase stator winding of the ordinary alternator, the number of winding turns is increased and the terminal is drawn out, and a set of three-phase bridge rectifier is added. At low speeds, it is output in series by the original winding and additional winding, and at higher speeds, it is only output by the original three-phase winding.

    Automatic engine start-stop is to automatically turn off the engine when the vehicle stops temporarily during driving (such as waiting for a red light). When it's time to move on, the system automatically restarts the engine. English name:stop&start, referred to as intelligent fuel-saving system, is a set of control engine start and stop system.

    It is by implanting a reinforced motor with an idle start-stop function in the traditional engine, so that the engine is completely extinguished and does not work when the car meets the idle stop conditions. When the whole vehicle needs to start and move forward, the idle start-stop motor system quickly responds to the driver's start command, quickly starts the engine, and connects instantaneously, thereby greatly reducing fuel consumption and exhaust emissions. STT is an abbreviation for Stop&Start.

    The STT Intelligent Fuel Saving System is a system that controls the start and stop of the engine. The system judges the state of the vehicle through the computer, such as the vehicle is in a stagnant state such as red light and blockage, and the computer can control the engine to automatically stop running, and the stop operation stage does not affect the use of air conditioning, audio and other equipment in the car.

    With this technology, fuel savings of up to 5% can be achieved under normal road conditions and up to about 15% in congested road sections. According to authoritative tests, the use of this technology will allow an average car to save 10% to 15% of fuel per year.

    The detailed introduction of the car generator when it starts is as follows: 1. The reason why the generator will turn off after starting. First, it is oil-free; the second is the blockage of the oil circuit; the third is that the body temperature is too high; Fourth, the load is too large, if the machine time is not very long or the life is not long, replace the spark plug and carburetor, and the piston ring needs to be replaced for a long time.

    2. The composition and function of the generator. Gasoline generator is usually composed of stator, rotor, end cover and bearing and other components, the engine is a machine that converts chemical energy into mechanical energy, the conversion process of the generator is actually the process of the work cycle, that is, by burning the fuel in the cylinder, generating kinetic energy, driving the reciprocating motion of the piston in the engine cylinder, thereby driving the connecting rod connected to the piston and the crank connected with the connecting rod, around the center of the crankshaft to make a reciprocating circular motion, so as to output power.

    1.Check that the tank has enough gasoline. 2.Check the fuel valve and oil pipeline for oil leakage. 3.Check that the oil oil is between the upper and lower limits. 4.Check the oil quality to determine if it needs to be replaced.

    1. The time of taking the power is too short, in the case of serious battery loss, when the battery is powered, it is necessary to wait for about 10 minutes, because at this time the battery has no power at all, and the current generated by the generator in a short time can not maintain the power supply system of the whole car, so do not unplug the external power supply in a hurry, you can charge it for a while.

    2. The reason why the generator does not generate electricity, under normal circumstances, the car is not maintained by the power of the battery during normal operation, but after the power is out, the car will still turn off through the external power supply, that is, there is a problem with the generator and a new generator needs to be replaced.

    3. Due to the long-term use of the battery, and there is no regular maintenance, it will also cause the aging of the battery, which will lead to the situation of flameout. If the battery is properly maintained, it can generally be used for about 5 years, so it is necessary to pay more attention to the rules of use of the battery in ordinary times and try to make its service life longer.

    Hello dear, happy to serve you . The failure of the generator to stall properly is usually due to the following reasons: Ignition system failure:

    It could be that there is a problem with the spark plug, or that the ignition coil or ignition control unit is faulty, causing the ignition signal to persist and the engine cannot be shut down. Fuel System Failure: The Burning Line Early Fuel Injector may be injecting fuel all the time, preventing the engine from stalling.

    Or the fuel pump pressure is too high, resulting in the oil and gas cannot burn normally. Electrical faults: It could be a short circuit in the circuit, or a malfunction in the generator control unit, causing the generator to run all the time.

    Expansion: If the generator cannot be turned off normally, the generator should be stopped immediately, and professional technicians should be found for repair and maintenance to avoid more serious safety accidents. Thank you for your trust, the above is my reply, I hope it can help you, I wish you a happy life and all the best

    Summary. If the generator does not generate electricity, it can run up and down 30 kilometers with the help of batteries. When the battery dies, the car stalls and stops driving.

    If the generator does not generate electricity, it can run up and down 30 kilometers with the help of batteries. When the battery dies, the car stalls and stops driving.

    The power generation is, the battery fault light is always on, do you need to change the generator?

    The generator is producing normal electricity. But the generator light is on. This may be due to a damage to the generator regulator that causes the generator to go into a protective state. It is recommended that the vehicle use a diagnostic device for diagnosis. Reads whether the engine system stores generator-related fault codes.

    Change the battery and try to see if it's a battery problem.

    The car mechanic used the computer for a long time, saying that there was a problem with the generator, and the power generation was, and said that it was not a big problem for me to use it first.

    It is normal for the car generator to generate electricity between the times.

    There's no problem with the amount of electricity.

    The master said that 14-15 is normal, but the power generation is insufficient, and the battery fault light is always on, and there seems to be no problem with normal opening.

    I think you can try it out with a different battery.

    My car is Changan Ford Focus, 14 two-phase ones, are you familiar with this car, can you really change the battery?

    Fox generators generate about that.

    Yes, but not like you.

    It's not that it's really possible, I suggest that you find a battery and try it out to see if it's the battery reason.

    Okay, thank you for giving it a try tomorrow, no, it's just a generator change, right?

    Basically, you can try, but I don't think there's any need to change because if the generator fails, it won't be generated.

    It is also recommended that you check with another repair shop.

    The reasons for the automatic flame-off after the generator is started are as follows:

    1. The flame-out switch is not turned on, and the flame-out line is short-circuited. Lack of engine oil (models with protectors).

    2. Sensor: Unplug the oil sensor cable, and the oil change sensor that can be started by the gasoline engine.

    3. Ignition system problem: pull out the spark plug and start empty, observe the spark, the spark is white and red; If there is no spark, replace the spark plug or igniter.

    4. Oil supply system problem: check whether the fuel is flooded, and if the water is ingress, clean the carburetor with gasoline. To judge whether the cylinder block is fueled, pull out the spark plug and press the air filter hole with your fingers, start it a few times in the air, and smell whether there is fuel smell in your fingers.

    Judge whether the oil supply channel is leaking, and change the position of the damper to see if it can be activated.

    5. Problems with energy conversion system and gas distribution system: pull out the spark plug and press the air filter hole with your fingers, and start the air pull a few times if there is no compressed gas flushing out, indicating that there is a problem with the energy conversion system and gas distribution system.
