1. Alternator failure
The car's alternator can charge the battery. The key is that after the car is started, almost all the electricity used by the car. is ensured by the alternator. You can look at it this way, if the generator breaks down and no longer produces electricity, the entire electrical consumption of the vehicle will be borne by the battery. Without a generator to charge the battery, the energy will quickly run out and the ignition system will run out. will not be able to work. In other words, the battery will not be able to produce electricity. Once the engine stops producing electricity, the car will stall quickly.
So, generator failure is one of the main reasons why an automatic car may stall while driving. When the generator fails, the battery light will turn on. In fact, under normal circumstances, generators fallrarely fails and most failures are caused by aging and breakage of the generator belt. The rubber parts of the car will age, including the generator belt, which is prone to breakage due to aging. Therefore, the best way to avoid flameouts caused by generator failure is to preventatively replace the generator belt.
2. Ignition System Faults
For the car's ignition system, the spark plugs, ignition coils, and cylinder lines are most likely to have problems, and the spark plugs are most likely to cause problems. If the spark plugs or ignition coils of more than 2 cylinders fail, the car may stall while driving. However, compared to spark plugs, we are generally more likely to ignore problems with bobiignition nes.
Spark plugs are consumable parts and have a lifespan. They are part of the maintenance items and must naturally be replaced regularly. The ignition coil is also a consumable part and also has a lifespan. However, the lifespan of ignition coils is generally longer than that of spark plugs, typically reaching more than 100,000 kilometers.
3. Oil circuit failure
An oil circuit failure is easy to understand. Too low oil supply pressure will cause cars with automatic transmissions to stall while driving. Oil line failures include blocked oil line, fuel pump failure, and high pressure oil pump failure (direct injection engines typically have two oil pumps, one of which is one is a high pressure oil pump). The principlesTwo places where the oil system is easily clogged are the fuel pump filter, fuel filter and fuel injector. Regardless of which part of the oil system is having problems, the car can stall due to poor fuel supply.
When the car engine suddenly stalls, we need to follow the following steps to solve the problem: 1. After you stop and park the car. 2. Check the engine: Is the battery working properly? Is the water tank normal? Is the motor belt loose or broken? Is there any abnormal noise inside the engine, etc.? problem with the battery, you can hear it when turning on. The sound is slower and quieter than the normal startup sound. 4. If it is a water tank problem, the engine water temperature will be high and there may be no water in the water tank. Do not open thewater tank indiscriminately. Sometimes the water in the water tank vaporizes and expands due to the problem. high temperature. 5. If there is an oil circuit problem, the engine will feel an obvious sense of frustration. 6. If it is a belt problem, the generator belt is loose and the power supply will be insufficient. If the belt is broken or lost, you can only wait for help. 7. Remember not to roll the car easily and start it. when the car suddenly breaks down while driving. However, there are generally three common reasons why a car suddenly stalls while driving. The following are for your reference in case of emergency. The cause of a car suddenly stalling while driving is a circuit fault. and stall while driving. At this point you can mainly check the ignition and start switches as well as the box.you with fuses. A short circuit in the low voltage line causes a shutdown, which in this case is intermittent. Check the car's low-voltage circuit. If the car suddenly stalls while driving, the device failure problem is usually the ignition coil, capacitor and electronic ignition module. It starts first, then shuts down after a while, then restarts, then shuts down again. The car suddenly stalled while driving. The oil system failed, the fuel pump was damaged, the oil pipe was broken, the carburetor oil inlet was blocked, and the fuel tank was empty. But in this case the car can restart, but it will be difficult.
