What is the reason why cars don't catch fire occasionally?

The reasons why the automobile engine won't catch fire are as follows:

1, the car battery is low in power or oil, which is the easiest item to check, and it is also the easiest reason to cause the car to fail to catch fire. It is easy to judge the fuel quantity. Turn the ignition key to the on position, press the start button twice without stepping on the brake, and turn on the headlights. The lights obviously change from strong to weak or simply don't light up. Then press the horn, the sound of the horn is obviously weaker than usual, or it doesn't ring, so it can be judged that the battery power is low.

Once these two situations occur, you can choose to ask the surrounding car owners for help according to your own situation and apply for emergency measures such as taking electricity, borrowing oil and towing.

2. The steering wheel is locked and cannot be started. This is a common anti-theft function that many cars have. After the car key is removed, the steering wheel does not turn back and turn, which will lead to the start of the self-locking function of the steering wheel, the steering lock pin and the steering column are buckled together, and the steering wheel cannot move or catch fire.

The solution is simple, that is, twist the key while shaking the steering wheel, otherwise it is impossible to twist the key even if it is broken.

3. Check the gear of the car. Under normal circumstances, when auto start is automatically shifted, the P gear or N gear is the correct gear. If the owner is careless for a moment and shifts the gear to R gear or other gears, the result will not only fail to catch fire, but also cause safety hazards.

There is no response when the car engine is electrified.

1. There is no response when the vehicle is powered on, and the instrument light is dim: under normal circumstances, if the battery light is on before starting the instrument panel self-inspection, it is obvious that the brightness of the instrument panel is not normal, and it can be judged that the battery is dead or has reached its service life.

Sometimes the instrument doesn't display, but when you start the car, you can obviously feel that the engine is running very slowly, which is also a precursor to the loss of battery power. The best solution at this time is to replace the battery in time.

2. The battery does not lose power, and the engine starts normally: after the ignition is pressed, the engine sounds normally, and the screen or the indicator light in the car does not darken obviously when working, indicating that there is nothing wrong with the battery and the engine. If there is no fire at this time, there may be something wrong with the high-pressure oil pump and the driving computer, or the engine has no oil supply, so this situation can only be called trailer rescue.
