Volkswagen Polo car when it was refueling urgently, I felt that there was a fire failure, what happe

Hello! In the case of yours, it is generally caused by poor engine combustion, and there are generally the following reasons.

First, the fuel pressure is too low, resulting in insufficient fuel supply and insufficient power, it is recommended that you clean the injector and check the oil pressure at the same time.

Second, if the ignition is not good, resulting in poor combustion, and at the same time obvious waste oil, it is recommended that you replace the spark plug.

That's it. Third, the cylinder pressure is insufficient, which is a common manifestation of lack of cylinder trembling, which is also a lack of power, and this needs to test the cylinder pressure.

Fourth, the engine intake and exhaust are not smooth, which is generally a three-way catalytic converter in the air filter position and exhaust.

The location is more problematic.

It is recommended that you go to the repair shop as soon as possible for a comprehensive inspection. [Car questions, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

Hello: Check that the spark plug gap is too large, and the ignition system has a misfire fault caused by the aging of the cylinder line.

Check the oil pump pressure, the oil pump is relieved or the oil supply is insufficient due to the blockage of the air filter. Hope mine can help you, hope. [Car questions, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

Hello: If the engine can't keep up with the throttle speed when the accelerator is urgent, it may be caused by poor throttle signal, carbon deposition or injector carbon deposition, and this situation will also occur if the spark plug is not working well. [Car questions, ask the car master.]

Reasons for stalling: 1. Automatic transmission models: 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, and the main reason is that the engine stalls due to carbon accumulation due to the use of inferior fuel (many gas stations sell impure oil for profiteering).

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

3. Finally, for the old models, the reason for the stalling is not enough driving skills, that is, the use of substandard oil to make the engine collect carbon, etc., resulting in the failure to seep the flameout.

Automatic Troubleshooting:

Pay attention to the place: for the phenomenon of automatic transmission car stalling, it is mainly caused by the use of inferior fuel. One is to go to a regular larger gas station to add high-grade oil, such as using 97 gasoline, although it is a lot more expensive, but it can ensure a longer life of the car and good power in operation.

Practical operation: shout to grind the left hand to grasp the steering wheel 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 journey, 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-ignition, and then restore the AT gear to D gear for normal driving.

In addition to the unskilled driving skills, the reason why the Volkswagen Polo does not catch fire is caused by the use of substandard engine oil to accumulate carbon in the engine. Volkswagen polo can not hit the Hongling fire must first check the oil circuit and circuit, but also need to check the high-voltage bag, ignition coil, motor, flywheel gear ring, spark plug and many other factors.

For older models, the reason for stalling, in addition to unskilled driving skills, is the stalling caused by carbon accumulation in the engine using substandard oil. Automatic Transmission Troubleshooting: Where to Usually Pay Attention to:

The phenomenon of automatic transmission stalling is mainly caused by the use of low-quality fuel. First, increase the use of high-quality oil at regular large gas stations, such as the use of No. 97 gasoline. Although it is much higher, it can guarantee a longer service life and good driving force of the car.

However, some car owners are eager to add 90 oil cheaply. Although low, there may be problems in the future.

The second is to go to a qualified large gas station to refuel! Actual operation: Hold the steering wheel firmly with your left hand (because there is no power, so you must hold it firmly), press the brake firmly with your right foot, slow down as much as possible, and quickly hang the AT gear to N gear.

Note: When re-ignition, be sure to hang the n gear, not the d r p gear, otherwise the vapor Qi car will not ignite or the car gearbox will be damaged. Then, retract the key and re-ignite.

Reason for flameout:1. Automatic transmission models:

Automatic transmission models do not stall easily, while manual transmission models may stall frequently due to low driving skills. However, it is not ruled out that the automatic transmission car will not turn off Wu Zhisen. The main reason is the use of inferior fuel (many cavity gas stations ** impure oil for profiteering), resulting in the engine stalling due to carbon deposits.

2.In addition, the stalling of a new car (automatic transmission) is mainly caused by unskilled driving skills, and there is also a possibility that there is a problem with the car's engine or oil circuit. However, for new cars, the possibility of problems with the engine itself is relatively small, and most of the reasons are oil circuit problems.

3.Finally, for the old models, the reason for the flameout, in addition to the unskilled driving skills, is the stalling caused by the use of substandard oil to accumulate carbon in the engine. Automatic transmission troubleshooting:

Although it is much higher, it can guarantee a longer service life and good driving force of the car. However, some car owners are eager to add 90 oil cheaply. Although low, there may be problems in the future.

The second is to go to a qualified large gas station to refuel! Actual operation: Hold the steering wheel firmly with your left hand (because there is no power, so you must hold it firmly), press the brake firmly with your right foot, slow down as much as possible, and quickly hang the AT gear to N gear.

Note: When re-ignition, be sure to hang N gear, not D r P gear, otherwise the car will not ignite or the car gearbox will be damaged. Then, retract the key and re-ignite.

1. Inferior fuel is used: bad fuel causes the engine to stall due to carbon deposits.

Solution: Replace the oil product.

2. Unskilled technology: The reason for the stalling of new cars is mainly caused by insufficient driving skills. (for newbies only).

Solution: Practice more.

3. Engine carbon deposition: the use of substandard oil to cause the engine to cause carbon deposition.

Solution: Change the oil and clean up the engine carbon deposits.

4. Vehicle power supply system failure: If the vehicle battery is completely damaged and has no power, or the positive and negative poles of the battery are not firmly connected, and there are traces of looseness. At this time, the engine cannot be injected normally through the fuel injector, and the engine fuel injector is likely to fail to open normally, resulting in abnormal engine work and flameout.

Solution: The battery performance is seriously deteriorated, and it should be replaced immediately, and the corresponding faults are insufficient capacity of the single battery and large internal resistance of the single battery.

5. Engine fuel injection system failure: During the normal driving of the vehicle, if the engine leakage suddenly has a fuel injection failure, the oil circuit is not smooth, the engine fuel injector is blocked, or the engine fuel pump is blocked, the engine can not supply oil normally, and the car computer is short-circuited and power-off, which will cause the vehicle to turn off automatically.

Solution: In view of the engine failure caused by poor gasoline quality, replace the best oil products, and go to the service station maintenance point to use a computer detector to check the vehicle engine system.

6. Loosen the clutch too fast when starting or going uphill: For many owners of manual transmissions, at the beginning of the start, the clutch will be lifted too quickly will cause the flameout, this is because the power take-off gear will slide to the transmission gear of the wheel and lean quickly, if the clutch is loosened soon, it will cause the gear to be unable to connect immediately.

Solution: According to the sound of the engine, listen to the engine sound, if the engine speed sound has dropped significantly, the sound decreases at this time the clutch has been lifted to half, and the state of linkage can be gently oiled.

7. The oil pressure of the oil pump is too low: the low pressure of the gasoline pump will directly cause the vehicle to fail to start, and the lighter one will cause the engine to be weak and weak, and the engine will swing when accelerating until it is turned off.

Solution: Go to the 4S shop to replace the oil pump control valve or safety valve.

8. Poor work of the idle control system: The undesirable phenomena of the engine in the idle state include whether there is air leakage in the pipe interfaces, vacuum hoses, exhaust gas recirculation system and fuel system of the gas system, and check whether the idle control valve of the car is working normally.

9. Spark plug failure: it will lead to insufficient ignition energy or even high voltage electricity, ignition of oil and gas in the cylinder, and the car cannot start, and even if it can start, it may suddenly turn off.

Solution: Replace the spark plug in time.

Volkswagen Polo can not catch fire must first check the oil circuit and circuit, but also need to check the high-voltage bag, ignition coil, motor, flywheel gear ring, spark plug and many other factors.

Volkswagen Polo was born in 1975, and in the following 30 years, after five generations of product evolution, the total production of more than 7 million units, and has long ranked first in the sales of German economy small cars, known as the wonder boy of German Volkswagen. The Polo sedan has also long been regarded as the standard for reliability, comfort and safety in an economical small car.

With the same level of models can not provide the handling performance, whether in the process of high-speed driving, or in the city at low speed, Polo has always maintained good stability and maneuverability, there is no obvious fluttering feeling in the high-speed process, the steering has always been accurate, low-speed cautious and noisy acceleration and deceleration, up and down through the ease of ease, so that Polo's handling has reached a new level.
