What are the reasons why the car stalls when it runs?

There are many reasons for the car to turn off, for the ignition is not very sudden, there is a process, first feel that the car is a little unable to get oil, the situation is getting more and more serious, until the ignition, this situation is mostly oil circuit failure. If the flameout is sudden, it is mostly a circuit failure.

fire and oil outages caused by electrical wiring; The fuel injector is blocked and does not inject fuel, or it is damaged by itself; ignition coil burning, distributor burning; Electronic oil pump failure, burnout or conduction failure; The oil circuit is blocked, and the oil supply is not smooth; clogged blue filter; Due to improper maintenance, long-term wear, lubrication, etc., the accumulation of "small faults" can also cause stalling.

I think it may be that the oil circuit is blocked, and the oil attack is not smooth. It is recommended to thoroughly clean the oil circuit, including fuel injectors, throttles, fuel tanks, etc. Just clean it up and you're good to go. ‍‍

Fuel quality, ignition coil failure, spark plug failure, coolant overheating.

I think maybe it's the oil problem, and then there's the fault of the driving computer, which causes the fuel injection to be inaccurate and suddenly turn off.

Because the throttle is released, there is only a small gap at the throttle for air to pass through, and when there is too much carbon deposited in the gap, the amount of air passing through is greatly reduced, and it is not enough to maintain the mixture required for idling, and the engine will stall. However, this can be prevented, usually when ignition, you can feel it, it is not good to ignite, and even need to step on the accelerator to play, which is a sign of excessive carbon accumulation at the throttle, which needs to be cleaned up in time.

There is no oil, or there is a failure in the fuel supply system, it may be a fuel pump, there is a problem with the pipeline, the second problem is that there is a problem with the ignition system, the battery is out of power, and the ignition coil, cylinder line, and spark plug are faulty. Other reasons may be a problem with the line.

I don't know what kind of car your car is, we often encounter this situation, which is generally caused by some sensors of the car's electronic control system, it is recommended to use a computer to detect faults, and repair them according to the detection faults. Such a problem arises at 10,000 kilometers. After eliminating the oil circuit and circuit faults, the most likely is that the crankshaft connecting rod mechanism is loose or severely worn.

Flameouts caused by carbon deposits, especially at the electronic throttle, are faulty in the intake area. When there is a very, very large amount of carbon deposits at the throttle, the engine may stall as soon as the throttle is released during driving, which happens from time to time in some very old cars.

Most of the problems are in the computer version, read it with a decoder, and if you can't read the fault, you can decode it when the fault doesn't catch fire! Because the car is still under warranty, it should be solved as much as possible, and it will cost you your own money to repair it after the warranty period! It may also be that the oil enters the carburetor, does not burn fast, drives for a while, and turns off the fire after 10 minutes and it is good again, go to check the carburetor and look between the oil tank.

Although there are various situations of stalling, the analysis of its reasons is mainly due to the clutch, throttle, braking and improper gear coordination, which requires novices to familiarize themselves with the vehicle they are driving as soon as possible, master the weight of the accelerator pedal, the length of the free stroke of the clutch, and adjust it if the pedal position is not suitable.

Oil supply failure, generally the gasoline pump is damaged, unable to pump oil. The life of the gasoline pump is longer, so the damage generally occurs on the old car, and some cars break down when they are parked, resulting in no fire, and some are broken while driving. Power supply failures, usually caused by damage to the ignition coil, resulting in no high voltage for all spark plugs.

Faulty electronic components, such as engine computers. All the operations on the car have to go through the engine computer, and after it is broken, there is no signal, and no instructions can be issued, so many other parts do not know how to work, so they do not work, resulting in stalling.

If the engine sometimes stalls when idling, and it is normal after restarting, it is called "intermittent idle stalling", this fault is very difficult to investigate, and there are many reasons for it, and various parts or circuits are not completely damaged, and the more headache is that the engine can be restarted after the engine occasionally stalls and can return to normal.

So even if the engine idles off due to a sensor, the engine ECU will consider this phenomenon not to be a fault.

Most of the problems are in the computer version, read it with a decoder, and if you can't read the fault, you can decode it when the fault doesn't catch fire! Because the car is still under warranty, it should be solved as much as possible, and it will cost you your own money to repair it after the warranty period!

1. There is a problem with the fuel quality: there is water or impurities in the fuel tank. The oil head is clogged, the filter is not clean, the oil supply system is checked and cleaned!

2. If there is a problem with the circuit, check the electronic igniter, high-voltage wire, etc.;

3. There is a problem with the circuit board.

Poor operation of the computer main relay, or oil pump relay, poor crankshaft position sensor or igniter when hot!

It is possible that the oil went into the carburetor and did not burn fast, and after driving for a while, it went out, and after 10 years, it was fine again, and I went to check the carburetor and went between the fuel tanks, and I looked.

Hold the steering wheel with your hand to stabilize the direction (because there is no power assist, so you must stabilize it hard), press the brake with your right foot to reduce the speed as much as possible, and then quickly hit the AT gear to N gear, (Note: The re-ignition must be in N gear during the march, not D r P and other gears, otherwise, the car will either not ignite, or the car gearbox will be damaged), and then set the key back one notch, and then re-ignite, and then restore the AT gear to D gear normal driving.

The reasons why the car suddenly stalls while driving are as follows:

1. Circuit failure. This possibility is that during the driving process, due to low-voltage power failure, stalling, at this time you can mainly check the ignition and starter switches and fuses.

2. Electrical device failure。This problem is generally the ignition coil, capacitive electric, electronic ignition module. It starts at first, turns off after a while, and then starts again and turns off again.

3. Oil circuit failure。The gasoline pump was damaged, the oil line was ruptured, the carburetor inlet was clogged, and the fuel tank ran out of oil. But in this case the car can be restarted, but it is difficult.

4. Sensor failure。Faults such as throttle position sensor, intake flow sensor, intake pressure sensor, crankshaft position sensor, camshaft position sensor, etc., and if the sensor fails, there will also be flameout failure.

5. Other faults。The engine timing system is out of order. The timing system calibration is incorrect, the engine top valve, etc., is a more serious failure, can not get on the car, can only apply for rescue.

The solution to turn off the car.

1. First of all, it is necessary to determine the reason for turning off the ignition. If the car with automatic transmission stalls, it is generally caused by the use of low-quality fuel, in this case.

2. The general operation is as follows: grasp the steering wheel with the left hand to stabilize the direction, press the brake with the right foot to reduce the speed as much as possible, and then quickly hit the AT gear to N gear (note: the re-ignition must be in N gear during the march, not D r P and other gears, otherwise, the car either cannot ignite, or the car gearbox will be damaged), and then the key is set back, and then re-ignition, and then the AT gear is restored to D gear for normal driving.

3. Secondly, if the car with manual transmission has stalled, under the premise of quickly improving their driving skills, they must first judge whether the oil road is smooth. Completely dredge the oil circuit, including the fuel injection cavity slip adjustment, throttle and fuel tank, etc., it may be that the quality of the engine oil you add is not passed, and the oil channel is blocked due to too much grease.

Is there electricity, it will turn off if there is no electricity.

Check the generator and battery.

There are other reasons that can cause flameout.

The manual car applied the brakes without pressing the clutch or the spark plug was broken.

What is the reason why the car suddenly stops while runningWhen the car suddenly stops, you need to pull over first on the premise of ensuring safety. During this time, you should apply the brakes slowly, not suddenly and suddenly, to prevent rear-end collisions. In addition, it is normal for the steering force and braking force to disappear after the ignition is turned off.

In this case, you should not panic. You can turn on the dual flashing lights to notify other vehicles that there is something wrong with your car. When you hit the brakes, you should keep pressing them.

If you can't press it, let it go, because you may not be able to press the brakes again. After stopping on the side of the road, try ignition again to see if it succeeds. If the ignition is successful, don't rush to leave, check the vehicle for abnormalities first.

For example, whether there are faulty lights on the dashboard, whether the vehicle is abnormal noise or shaking, etc. If there is no abnormality, start driving again. Then go to the nearest car repair shop and have a professional check it out to see what is wrong.

If the ignition fails again, you can only contact the 4S shop or auto repair shop through ** and let the trailer tow away. There are too many reasons that may be involved when a car suddenly stalls while driving, such as fuel system failure, ignition system failure, circuit failure, electrical component failure, fuel system failure, sensor failure, and so on.

The reason for the sudden flameout.

1. Engine stalling is one of the common reasons:

a. Engine stalling is one of the common reasons for land wind stalling, which is manifested as the unstable operation of the engine when idling, and the exhaust pipe makes a purring and purring sound.

Solution: The main cause of the fault of the car stalling in the idle state is due to too much dust in the air, which can be solved by cleaning the idle motor.

b. The engine is shaking, followed by stalling, and the second start will be normal!

Solution: Replace the gasoline filter, clean the throttle, and check the spark plug combustion. Or you can turn the ignition switch to the power-on self-test state first, stay for dozens of seconds, let the oil, oil pump or something run for a while, and then ignite.

2. Troubleshooting method for automatic transmission car shutdown:

Pay attention to the place: for the phenomenon of automatic transmission car stalling, it is mainly caused by the use of inferior fuel.

Practical operation: Hold the steering wheel with your left hand to stabilize the direction because there is no power assist, so you must stabilize it hard, press the brake with your right foot to reduce the speed as much as possible, and then quickly hit the AT gear to N gear, then take the key back one notch, and then re-ignite, and then restore the AT gear to D gear for normal driving.

3. Troubleshooting method for manual transmission car stalling:

Solution: Clean the oil circuit thoroughly, including fuel injectors, throttle valves, fuel tanks, etc. It may be that the quality of the oil you add is not up to standard, there is too much grease, the oil path is blocked, and the oil attack is not smooth.

4. Long-term parking is not used

Land breeze flameout is closely related to long-term parking and non-use, because long-term parking can lead to lubrication or electrical problems.

Solution: Do a thorough maintenance before reuse, change the oil, filter, etc., and check the fuel, circuit, etc. as appropriate.

Here's why:1. Circuit failure: This may be due to low-voltage power failure during driving, resulting in engine stalling. In this case, the ignition and starter switches as well as the safety gossamer box can be checked.

2. The problem of electrical equipment failure is generally the ignition coil, capacitor, and electronic ignition module. You can start it first, close it after a while, start it again and bury it again.

3. The oil circuit is faulty, the gasoline pump is broken, the oil pipe is broken, the carburetor liquid dissipation inlet is blocked, and the fuel tank is empty. But in this case, the car can be restarted, but with difficulty.
