What to do if the car suddenly stops? What to do if your car suddenly stops

There are generally 5 reasons why a car suddenly stalls while driving:

1. Circuit failure. This possibility is that the power is cut off due to low voltage during driving. At this time, you can mainly check the ignition and starter switches, as well as the fuse box.

2. The low-voltage line is short-circuited and causes the flameout, in which case it is intermittent flameout. Check your low-voltage lines.

3. Device failure. This problem is generally the ignition coil, capacitive electric, electronic ignition module. It starts at the beginning, turns off after a while, and then starts again and turns off again.

4. 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.

5. Ignition system, engine overheating and detonation system will turn off if there is a problem.

If the vehicle suddenly turns off during driving, don't panic, try your best to stabilize the car and don't hit the direction, turn on the double flash, bring a little braking as the case may be, if it is a manual transmission car, you can step on the clutch, hang the gear lever into the corresponding gear according to the speed, and then release the clutch, use the speed to drive the engine, similar to a cart to start the engine, or you can directly restart the engine; If you are an automatic car, first carefully put the gear into neutral, be careful not to put it into reverse gear by mistake, otherwise it will damage the transmission, and then restart the engine.

The main reasons for the general car stalling:

1. Use low-quality fuel. Once the automatic car stalls, the main reason is the use of inferior (not up to standard) fuel, which in turn causes the engine to depot and stall.

2. Engine computer failure. From the point of view of kilometers, after using the car for a long time, the possibility of engine computer failure will be relatively large, once the engine computer fails, it will cause the car to stall, which is a problem of control. Just like the human brain, when there is a malfunction, the body "goes out".

3. The driving skills are not proficient enough. The driver's unskilled driving skills and improper operation will also cause the car to stall.

4. Multiple cylinder failures at the same time. It is possible that due to the failure of the spark plug or the high-pressure bag, one or more cylinders will not ignite, resulting in a flameout. However, only the failure of multiple cylinders at the same time and non-ignition can cause flameout, so there is such a possibility, but the probability is not large.

5. The engine itself fails. Damage to the engine idle motor or the wiring of the idle motor, or a problem with the idle control module in the engine's electronic control unit (ECU). The possibility of the engine itself failing is extremely high among the many reasons why a car stalls.

6. Oil pump failure. The stuck oil pump or the failure of the oil pump itself will cause a sudden lack of oil supply, and no oil supply will easily cause the car to stall.

Reasons for the sudden stalling of the car while driving:

1. Circuit failure.

2. Flameout caused by short circuit of low-voltage line: intermittent flameout; 3. Device failure: it can start at first, turn off after a while, and then start again, and then turn off again;

4. 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.

5. There is a problem with the ignition system and the explosion-proof system for engine overheating.

When it is found that after the ignition is turned off, according to the road conditions at the time, if there is no emergency, you can slowly step on the brakes to prevent the tail light, after the speed is reduced, slowly play the direction, drive to the roadside lane, pay attention, the brake should be stepped on all the time, the power from small to large, do not step on it and then loosen, and then go to the pedal, which will lead to the only remaining vacuum is also consumed, and then step on it can not be stepped on, park the car on the side of the road, turn on the four flashing lights, place the tripod, and hit the ** rescue trailer. Hope!

Now the performance of the engine is becoming more and more reliable, and it is rare for the vehicle to suddenly stall, which is generally caused by improper operation by the driver. Especially for manual transmission cars, if the "oil separation" is not well coordinated, or the power is insufficient, it is easy to be "suffocated" and stalled.

1. When the engine suddenly stops, don't panic at first, so as not to cause a bigger error.

2. If the ignition is suddenly turned off while driving, the ignition switch must not be completely turned off, otherwise the steering wheel will be locked and can no longer rotate, and the car is still moving forward at this time, and the consequences are unimaginable.

3. After the manual transmission car suddenly turns off in driving, you can step on the clutch pedal, shift to 2nd gear, and then lift the clutch pedal sharply, and the engine will automatically start again.

4. If it is suddenly turned off when driving at low speed such as crossing obstacles, going uphill, and on the road, it is generally caused by insufficient power, so it is best to stop the car, pull the handbrake, hang neutral gear, and start again.

The reason why the car stalled.

1.Automatic transmission models will not easily stall, while manual transmission models may often stall if the driver does not have a high driving level. However, automatic transmission cars also have the possibility of stalling, and most of them use low-quality fuel to cause the engine to build up and stall.

2.If the new car (automatic transmission) stalls, the reason is mainly caused by the lack of driving skills, and another possibility is the problem of the car engine or oil circuit, but for the new car, the possibility of the engine itself is less likely, most of it is the problem of the oil circuit.

3.For old models, the reason for the ignition is not only the lack of driving skills, but also the use of substandard oil to cause the engine to cause carbon deposits.

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 ridge.

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 ignition:

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: A thorough maintenance should be done before re-using Qingpei, replacing the oil, filter, etc., and checking the fuel and circuit as appropriate.

Sudden stalling of a car is mostly caused by circuit failures, such as ignition coils, fuses that burn out, sensors that are damaged, or critical components that fall off. It is advisable to pull over and wait for help.

Common faults with sudden flameout:

1.Faulty circuits.

The possibility is that while driving, the engine will shut down due to a low-voltage power failure. At this time, the switch of ignition and starter and fuse box 2 can be mainly checked

2.Failure of electrical equipment.

This question is generally an ignition coil, an electric container, and an electronic ignition module. That is, it can be started at first, shut down after a while, and then it can be restarted and shut down again.

3.Oil jam fault.

The gasoline pump was damaged, the oil line was broken, the carburetor inlet was blocked, and the tank was short of oil. But in this case, the car can be restarted, but it is very difficult.

4.Sensor failure.

Faults such as throttle position sensors, intake flow sensors, intake pressure sensors, crankshaft position sensors, and camshaft position sensors. If the sensor fails, it will also stall.

5.Other faults.

Engine timing system failure. Incorrect timing calibration of the system, engine top valves, etc. , are all serious breakdowns, so you can't get on the bus, so you can only apply for rescue.

Millions of car purchase subsidies.

A sudden stall of a car can be caused by gasoline, damaged gasoline pumps, damaged generators, damaged batteries, damaged spark plugs, damaged ignition coils, etc.

Fire, air, and gasoline are required for the engine to function properly. One of these three deficiencies will basically affect the engine stalling. The fire is caused by the discharge of the spark plug, so the absence of electricity will not affect the ignition.

Gasoline passes through a petrol pump and fuel nozzle**. Damage to the petrol pump or fuel nipple will affect the normal flow of gasoline** and will also affect the engine stalling. The air comes in through the air intake and is filtered by an air filter before entering the engine combustion chamber.

A clogged air intake or air filter can affect engine stalling.

Another cause that can affect engine stalling is an engine timing error. Timing errors can be caused by problems with timing chain skipping or variable timing systems. There is also a camshaft position sensor and a crankshaft macro head position sensor on the engine.

If these two sensors are damaged, the timing will also be affected.

When the engine is turned off while driving, it is not recommended to continue ignition driving, but immediately ask the trailer to be towed to the repair shop for testing. If you don't have gas, someone can deliver it. If there is enough gasoline left, there is a problem with one part of the car.

If the timing is wrong, continuing the ignition at this point may damage the engine.

Well, friends, that's all for today's brief introduction to the car series. Then, after you finish counting the masks, the car suddenly stops? Do you understand this problem?
