    Pedal clutch problem.

    Novices do not control the clutch well, and it is easy to raise the clutch too quickly and the vehicle accidentally stalls when driving. Therefore, when starting with a manual transmission car, the clutch should be well controlled and the left foot should be steady. Although automatic transmission cars rarely stall, if the clutch is lifted too quickly, it will also stall.

    Brake problems. Many novices drive manual transmission cars, and when braking, especially when braking suddenly, they often forget to step on the clutch at the same time, which will suffocate the car and turn off. So when braking, either take neutral or press the brakes and press the clutch at the same time. 3/4

    The problem of lack of fuel in the car.

    Lack of motivation problem.

    If there is a serious lack of power while driving, it will also cause stalling.

    The reasons for the automatic shutdown of the car after starting are: 1. The oil used is unqualified; 2. The oil circuit is not smooth; 3. The spark plug is faulty; 4. The fuel injector and fuel filter are abnormal; 5. The contact of the line plug is not good; 6. Driving skills are not skilled enough; 7. Short circuit and power failure of the engine or car computer; 8. Loosen the clutch too quickly when starting or going uphill; 9. The oil pressure of the oil pump is too low; 10. The idle speed control system is not working well.

    The maintenance steps of the automatic shutdown of the car are: 1. Turn on the car point switch, observe whether the indication of the gasoline meter is normal, and see if there is oil in the fuel tank; 2. Check whether the lower circuit is faulty; 3. Check whether the connecting wires of the starter and the battery are connected reliably.

    1. There is a problem with the throttle. For example, throttle blockage; throttle carbon deposits, etc.

    2. There is a problem with the ignition coil or spark plug. For example, the spark plug life has reached its limit; The spark plug gap is too large, etc.

    3. There is a problem with the fuel injector, such as the fuel injector is blocked. This phenomenon can be caused by a problem in any of the three parts of the fuel system, ignition system, and air intake system.

    There are four main causes of vehicle stalling: oil circuit, valve, circuit, and sensor failure. 1. When the engine is working normally, the oil pump will pump the fuel out of the fuel tank, enter the piping through the filter, and then spray it out from the fuel injector to form an oil-gas mixture.

    In this process, the fuel pump and injector are the most likely to fail, followed by the filter and oil circuit.

    Hello dear! This can be caused by a problem with the engine's idle control system, or due to insufficient injection pressure, or it can be due to a blockage in the air intake system. Generally, most of this failure phenomenon is caused by damage to the idle control valve.

    When the engine is in the idle condition, the throttle valve is almost fully closed, at this time, the idle control valve controls the amount of air entering the engine, if the idle control valve is damaged, it may cause a serious shortage of air entering the engine, which will cause the engine to stall without idling. This can also be caused by a blocked air intake or a clogged air filter, when the amount of air entering the engine is insufficient to cause the engine to stall. When the injector fails or the injection pressure is insufficient, the gasoline cannot be completely mixed with the air to form a flammable mixture, and the engine stalls.

    After this fault phenomenon occurs, you should go to the repair shop or 4S shop to check which part is the problem. Many riders do not pay attention to the working state of the spark plug and ignition coil during the usual maintenance, and the engine stalling may also be caused by insufficient ignition energy. After the spark plug and ignition coil are used for a period of time, the work efficiency will decrease, and the ignition energy of the spark plug will decrease, so the engine may stall, and it may also cause a cylinder to work poorly.

    The solution is to replace the spark plug or ignition coil.

    1.The general engine intelligent start-stop system is when your vehicle is waiting for a red light or congested road conditions, pressing the brakes normally will make the vehicle stop and put into neutral at the same time, and after releasing the clutch, the engine intelligent start-stop system starts, at this time the engine will stop working and enter the "fuel-saving mode".

    1.The idle speed is low, or there is no high idle speed. The rotational speed value of idle speed is about 950 rpm, and the low idle speed is mainly caused by dirty idle control valves, dirty fuel injectors, and carbon deposits in spark plugs.

    In addition, there is a problem with the intake air temperature sensor, water temperature sensor, and high idle program in the computer, but this is not very common. The problems of the idle valve, fuel injector, and spark plug mentioned above are mainly the result of long-term low-speed driving.

    Questions. And the clutch always can't lift what's going on.

    1. The clutch plate is seriously worn, 2. The return spring of the clutch pedal is loose, 3. The pressure plate is aging. Then there is the problem of internal leakage in the main pump and sub-pump.

    ps, can't hang the gear because the clutch has about 4 of the way back to the position, at this time there will be a sound of teeth when stepping on the clutch gear, can't hang in, this phenomenon is the most frequent after hanging the reverse gear. After lifting the clutch with my foot, it was normal again.

    Questions. Good.

    Hope mine is helpful to you.

    Vehicles with automatic transmissions suddenly stall when in use, in large part due to a blockage in the oil circuit, and some may be due to the failure of the automatic transmission.

    When the vehicle is used for a long time, the oil circuit needs to be thoroughly washed, including fuel injectors, throttle valves, fuel tanks, etc.

    In addition, if the oil is not of good quality for a long time, there are too many impurities in the oil sludge, which is easy to block the oil circuit, resulting in poor oil supply and flameout.

    If none of the above issues the problem of sudden flameout, then it is necessary to consider whether it is an automatic transmission failure.

    The reasons for the old engine stalling: 1. The engine intake pipeline is seriously leaking.

    2. The fuel pump and gasoline filter are blocked, so that the oil pressure is insufficient, which makes the engine easy to stall.

    3. If the water temperature of the engine is too high, the engine will automatically shut off when it enters the protection mode.

    4. Flameout caused by poor fuel quality (such as gasoline with water sinking to the bottom).

    Flameout caused by carbon deposits: Usually carbon deposits will exist in throttle valves, spark plugs, cylinders, oil circuits, air intakes, etc.;

    Oil and injector plugging: Adding inferior fuel will not only produce more carbon deposits, but also may clog the fuel injector, and the atomization effect is not good, and the inferior fuel directly affects the combustion effect, which increases the loss of fuel;

    Power supply problems in the ignition system: Common faults are carbon deposition in the spark plug and insufficient ignition voltage;

    Abnormal engine control system: If the battery loses a lot of power, it will make it difficult to start the engine, or even not start.

    Stalling of a car engine should be a fault that everyone has encountered, especially when learning to drive, stalling is commonplace, but it is usually caused by improper operation. Sometimes, if the car breaks down, it can also cause the car engine to stall. What are the causes of a car engine stalling?

    How to deal with it? In fact, the failure of a car engine to stall rarely occurs in a car and is usually caused by an oil circuit failure or a circuit failure. To take the simplest example, a car needs to consume fuel while driving. If the owner accidentally runs out of gas, the car's engine will naturally stall, and a similar situation can occur if the fuel system fails.

    The fuel system includes oil pumps, oil pipes, fuel tanks and other components. If we use low-quality fuel for a long time, it is easy to clog the fuel pipeline. At this time, if the oil circuit is not smooth, the fuel is not enough, and the engine will naturally stall.

    Moreover, the long-term use of low-quality fuel will also cause the engine to produce a large amount of carbon deposits, blocking the intake pipe and the oil rock road, which will cause the car to stall during driving. Therefore, it is very important to use high-quality fuel.

    Secondly, car circuit failure is also one of the common factors that cause the engine to turn off automatically. Currently there is an increase in the internal circuitry due to the lot of additional entertainment features on the car, and no one can guarantee that the circuit is 100% error-free. For example, the starter itself is a part that is easily damaged, and the engine needs to be driven by the starter.

    If the starter or related circuits are faulty or in poor contact, it can cause the engine to stall, so it is also important to check the car circuitry regularly.

    Finally, there are many parts in the car that have their own service life, such as the spark plug of the ignition system, which is one of the most important parts of the ignition system. At the same time, it also has a service life. Ordinary spark plugs will age and fail after 100,000 kilometers of use.

    At this time, the car engine vibrates and stalls. Similar parts include ignition coils, high-voltage wires, batteries, etc. The best way to solve these kinds of problems is to replace them before they fail.

    As long as we take care of our car, it will definitely not be a problem.

    1.Ignition failure: Ignition failure can stall the engine, and failure of spark plug or pole hochatensel detection equipment is the most common cause of ignition failure.

    2.Insufficient gas mixing ratio: Insufficient gas mixing ratio will make the engine run unstable, and it will stall when the rev speed is high.

    Common causes are throttle failure or clogged intake pipes, clogged air filters, and more.

    3.Fuel supply failure: Fuel supply failure is the second most common cause of engine stalling, when the engine lacks sufficient fuel ratio, it will cause the engine to stall, the common reason for this reason is that the fuel pipe is dirt or broken, as long as the dirt is cleaned up, or replace the fuel pipe with a new one, the problem can be solved.

    4.Circuit voltage failure: When the sensor or controller has a circuit voltage failure, the engine will stall due to lack of sufficient power, and the sensor and circuit that damage the letter wheel should be replaced in time to solve the problem. False limbs.

    1.The intake duct is really empty. 2.

    Improper idle adjustment, dirty throttle, and poor idle control system lead to unstable idling. 3.Unstable fuel pressure, such as excessive wear or poor contact of the electric fuel pump brush, or clogged fuel pump filter.

    4.The exhaust gas recirculation valve is clogged or the bottom is leaking. 5.

    Faults such as poor contact in the fuel pump circuit, injector drive circuit, and other circuits. 6.Fuel pump relays, EFL relays, and ignition relays are defective.

    7.The ignition system is not working properly. For example, the high-voltage spark is weak, the spark plug takes too long to eliminate the grip, the ignition timing is incorrect, the ignition coil is not in contact with the ignition coil or the short circuit between the hot turns leads to no high-voltage spark or weak high-voltage spark, the low-voltage line is in poor contact, and the insulating glue is damaged resulting in intermittent grounding.

    8.Poor throttle position sensor. 9.

    There is a problem with the air flow meter or the inlet pressure transmitter cavity sensor. 10.The coolant temperature sensor and oxygen sensor are faulty.

    The following is the solution to the automatic shutdown of the engine: 1. Check whether the fuel tank is sufficient or contains air and moisture, and the moisture content in the general oil circuit will cause insufficient combustion and cause flameout. Dredging and repairing tubing or joints.

    2. See if the filter is blocked, if the filter is a problem, you can consider cleaning or replacing the filter element. 3. Check whether the battery is powered. Press the horn button to hear if the horn rings.

    If it does not sound, it may be that the battery connection is loose or the low-voltage line is loose or broken, and the loose part is found for reconnection or repair. 4. Check whether the oil pump is supplied with oil, if the rack is stuck in the position of not supplying oil, the governor fails, and the lever falls off, then it needs to be corrected and repaired. 5. Check whether there is a problem with the spark plug.

    If there is a problem with the spark plug, it will also cause the flame to go out, and if there is a problem, you can replace the spark plug to solve the problem.

<>1. Generally, under normal circumstances, it is the sound of the valve or camshaft, why is there a valve sound, because when the engine is running, the intake valve and the exhaust valve will be opened alternately, the intake valve is opened to inhale the combustible gas mixture, so as to facilitate the combustion in the cylinder to promote the engine to run, the exhaust valve is opened to discharge the exhaust gas produced after the combustion of the mixture, 2. The structure of the valve is attached to the combustion chamber to play a sealing role, and the cylinder and valve are metal. The separation and fitting of the two pieces of iron from time to time will inevitably produce a collision sound; As for why there is a sound in the cam, it is also because of the structure, generally the cam is there with a friend called the rocker, and there is also a gap between them, and when the engine is working, they will also go back and forth slightly similar to the collision, which is also two iron bumps, and there may also be that sound.
