The car stalled while driving, what is the reason?

Suddenly turn on and turn off the ignition, first, your phenomenon should not be no oil, no oil, including the oil pump suddenly does not work.

It's that the vehicle keeps shaking, and then it shakes more and more, until it stops, and the fuel supply is not enough.

Second, another consideration is that there is no electricity, I think you should be clear about no electricity, including the motor has no strength, but after using Jianglong, it can be started after connecting, but according to your description, it doesn't look like there is no electricity, no electricity is very intuitive, you can see it yourself, so it is excluded that there is no electricity.

3. Circuit faults, there are faults in the circuits of old cars, including faults caused by rodent infestation.

Fourth, ignition failure, no ignition, no ignition when walking can lead to the common flameout is nothing more than a few, because I don't know what system you are using in the car, so to put it simply, such as distributor damage (skipping without distributor), high-voltage package damage, crankshaft position sensor failure, timing disconnection, in your description of the phenomenon I think it may be relatively large is that the timing belt is disconnected, so when playing the motor, only the crankshaft is rotating, and the camshaft is not rotating, so there is no compression, If you are lucky, the distance between the valve and the piston of this engine is far enough that they will not top each other, then you only need to change the timing belt (which may have to come with an adjustment wheel) to solve the problem.

If you are not lucky, then the valve and piston of the engine are broken, and you will need to spend some money.

If the vehicle can't hit in the process of driving, there are the following simple reasons: for a while, there is no oil, or the fuel supply system is faulty, it may be the fuel pump, the pipeline can be a problem, the second is "there is a problem with the ignition system, the battery is dead, the ignition coil, cylinder line, and spark plug are faulty. Other reasons may be a problem with the line. If you don't know much about the above points, it is recommended to go to a professional repair shop for repair.

After the ignition is turned off, is the meter not lit up? If so, it should be a problem with the power supply of the whole vehicle. This sudden flameout situation is still more serious, and you must go to the 4S store to check it:

After going, you can ask the master to check the fault code of the engine first. If there is a fault record, it will be troubleshooting. If there is no fault, check whether the power harness of the engine controller is falsely connected.

The main reasons why cars stall are as follows:

1. The driving skills are not proficient enough.

The driver's unskilled driving skills and improper operation will also cause the car to stall;

2. The oil pump is faulty.

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

3.Use low-quality fuel.

Once the automatic transmission car stalls, the main reason is the use of inferior (not up to standard) fuel, which in turn leads to carbon accumulation in the engine and stalls;

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.

Flameout troubleshooting method:

1. For novices, it is normal to turn off the engine halfway, and the main elimination method is to improve their driving skills after rapid running-in;

2. Use high-standard, high-quality and qualified fuel;

3. Clean the oil circuit thoroughly, including fuel injectors, throttles, fuel tanks, etc. It may be caused by the quality of the oil is not up to par, there is too much grease, the oil road is blocked, and the oil supply is not smooth

4. The main reason for the failure of the car stalling in the idle state is that there is too much dust in the air, and there is a lot of dirt deposited at the idle valve core and throttle seat when the engine is running. The solution to this problem is simply to clean the engine.

1. Automatic transmission models will not easily stall, while manual transmission models may often stall due to low driving level. However, it is not excluded that automatic transmission cars will not stall, the main reason is the use of inferior fuel (many gas stations sell impure oil in order to make huge profits) caused the engine to accumulate carbon and stall.

2. The reason for the stalling of the new car (automatic transmission) is mainly caused by the lack of skillful driving skills, and the other possibility is the problem of the car engine or the oil circuit, but for the new car, the problem of the engine itself is less likely, and most of the reasons are the problem of the oil circuit.

3. For old models, the reason for the flameout is not enough driving skills, that is, the use of substandard quality oil to make the engine collect carbon and other causes of flameout.

Take precautions against flameout. Ignition is a problem often encountered by novices in the process of driving, starting to turn off when the red light turns green, starting to turn off when following the car, not changing gears in time, stalling when the gear shift is not in time, turning off the ignition when the braking amplitude is too large and the steering angle is too large, etc., I believe many people have encountered it.

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.

90% of the car suddenly stalled because of the fault here, and the novice was pitted by the 4S shop, all because of this 1 point I don't understand.

Reasons for the sudden stalling of the car while driving:

1. Circuit fault;

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.

There are three reasons why the car turns off when it is open: 1. The car suddenly turns off while driving, which is a circuit failure, which may be due to low-voltage power failure and stalling during driving; 2. If there is a failure of the flame-out part, it is generally the ignition coil, capacitive electrical capacity, and electronic ignition module; 3. The oil circuit of the car is faulty, the gasoline pump is damaged, the oil pipe is ruptured, the oil inlet of the vaporizer is blocked, and the fuel tank is out of oil. Workaround after the car is turned off:

If it is a manual transmission, the car can directly restart the engine; If you are in an automatic car, carefully put the gear into neutral first, be careful not to misplace it in reverse gear (R), otherwise it will damage the transmission, and then restart the engine.

The car may be driven and turned off because of the driver's error, or it may be due to a breakdown of the vehicle. If the vehicle suddenly stops while driving, try to stabilize the vehicle as much as possible and do not turn the direction, and apply a little brake if possible until the vehicle comes to a stop.

But it is not excluded that the car with automatic transmission will not stall. The main reason is that the application of shoddy fuel oil is the impure oil of many gas stations** to obtain huge profits, resulting in the engine carbon deposition and stalling. Or there is a malfunction of the car's engine and oil circuits.

The cause of stalling is not only unskilled driving, but also the possibility of using substandard oil to collect carbon in the engine.

How to avoid stalling while driving

But it is not excluded that the car with automatic transmission will not stall. The main reason is that the application of shoddy fuel oil is the impure oil of many gas stations** to obtain huge profits, resulting in the engine carbon deposition and stalling. Or there is a malfunction of the car's engine and oil circuits.

The cause of stalling is not only unskilled driving, but also the possibility of using substandard oil to collect carbon in the engine.

Don't lift the clutch too high, if you don't let go of the handbrake, it will also turn off, and the front of the car will be raised a little, without having to go to the "perfect contact point". Because in the case of oil, even if the contact point is not fully lifted, the handbrake will not slip, and the car will not move.

In this case, don't look at the car and don't move on the panic, thinking that their clutch is not enough to lift the clutch and lift the clutch significantly, in fact, at this time, since it does not slip, it means that the clutch has been semi-linked more energetic, add fuel and lift a little clutch to become.

Of course, it is best if the clutch contact point can be well controlled (the front of the car is significantly raised, and there is no body shaking before the engine is turned off), at this time refuel, release the handbrake and walk away.

Caused by the driver's driving technique or a problem with the car itself.

Driver's driving technical reasons: This situation generally appears in driving manual transmission models, low gear high speed, that is, the speed of the car is too low, the gear is high, the speed of the car does not match the gear, it will stall.

There are many reasons for the problem of the car itself, such as the oil circuit system, ignition system, air intake system, and circuit system, and any part of the problem will lead to stalling.

If you usually maintain it on time, the most common reason is that the oil used is unqualified and there are too many impurities, which leads to the blockage of the oil inlet and the unsmooth oil path, which in turn leads to the flameout.

In this case, it is necessary to contact a 4S shop or a professional auto repair shop as soon as possible, so that professionals can conduct an inspection, and only by determining where the problem is, can the symptoms be repaired.

There are two reasons why the car is turned off when it is opened: 1. Because of the driver's reasons, this situation generally appears in the driving manual transmission model, and the automatic transmission model will not easily stall, the most common reason is that the low-speed and high-speed gear is the so-called low-speed high-speed, that is, the speed of the car is too low, the gear is too high, and the speed of the car does not match the gear, and it will be turned off. 2. There are many reasons for the problem of the car itself, such as the oil circuit system, ignition system, air intake system, circuit system, any part of the problem, which may lead to flameout, if the usual maintenance on time, the phenomenon of sudden flameout, the most common reason is that the oil used is unqualified, too many impurities, resulting in the blockage of the oil inlet, the oil circuit is not smooth, and then leads to flameout.

The car turns off while driving because the fuel tank is low or the sensor is damaged, the engine sensor signal is wrong, the fuse is falsely connected, the fuel quality is poor, and the fuel system is not working properly.

1. The fuel in the vehicle tank is insufficient, or the fuel level sensor is damaged;

2. The sensor signal on the engine is wrong, such as camshaft position sensor, oxygen sensor, crankshaft position sensor, intake pressure sensor, air flow sensor, etc.

3. The insurance is falsely connected, or the poor contact caused by the gap of the line plug is too large, or the line is short-circuited or broken, and the bumps in the driving process cause it to fall off, which leads to the stalling of the vehicle.

4. Poor fuel quality leads to lack of cylinders in the engine, or carbon deposits in the internal pipelines of the engine due to the throttle, fuel injector, and fuel injector.

5. The fuel system is not working properly, such as the fuel pump is damaged, the supply pressure is insufficient, the gasoline filter is blocked, and the oil pipe is not smooth.

Introduction to car maintenance

Car maintenance refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting or replacing certain parts of the relevant parts of the car, also known as car maintenance.

Modern car maintenance mainly includes the maintenance scope of engine system (engine), transmission system, air conditioning system, cooling system, fuel system, power steering system, etc.

The purpose of car maintenance is to keep the car clean and tidy, the technical condition is normal, eliminate hidden dangers, prevent failures, slow down the deterioration process, and extend the service life.

Automatic shut-off of automobiles is usually caused by oil circuit failures, circuit failures, and aging components.

1. Oil circuit failure.

Cars need 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.

In addition, long-term use of low-quality fuel can also cause the engine to produce a large amount of carbon deposits and block the intake pipe and oil circuit, which can cause the car to stall during driving.

2. Circuit failure.

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.

3. Aging of parts.

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.

How to deal with automatic flame-out:

2. Clean the oil circuit, including the fuel injector, throttle, fuel tank, etc., to keep the oil circuit smooth.

3. Remove the sensor and clean it.

4. Mainly check the switch of ignition and starting motor and the fuse box.

5. Clean up the dirt.
