What are the common faults and maintenance knowledge of automobiles?

The first one: burning oil. The phenomena of burning engine oil are: 1. Touching the exhaust pipe with your hand, you found black and wet sludge piled up and smelled engine oil. 2, the car exhaust pipe emits blue smoke. 3. Under the condition of no oil leakage, there is a serious shortage of oil.

There are two reasons why cars burn oil. One is the common problem of the model, which is difficult to solve.

One is the excessive wear and aging of engine internal components with the increase of vehicle age. In this case, the problem can only be solved by replacing excessively worn and aged parts.

The second one: vehicle jitter. There are many reasons for vehicle jitter. There may be something wrong with the chassis, and the front and rear suspension, steering, transmission and other structures are loose.

It may be a tire problem, such as the tire pressure difference between the four tires is too large; There is something wrong with the tire dynamic balance.

In addition, any part of the ignition system, air intake system and fuel system has problems, which may lead to the phenomenon of car jitter.

Solution: Make sure what's wrong with the car first, and then repair it.

Third: the instrument panel fault light is on. Such as engine fault light, tire pressure warning light, oil warning light, etc. This will vary greatly from model to model. It is recommended to check the vehicle instruction manual, which will have a clear explanation.

Solution: Stop and check. If the situation is serious, don't continue driving. Contact a 4S shop or a professional auto repair shop as soon as possible to seek professional help.

Fourth: the battery problem. For example, the battery is dead, and the battery life reaches the limit. There is something wrong with the battery, so the car won't catch fire. When there is a fire, there will be a "squeak" sound, and the car dashboard will light up the fault light.

The life of the battery is generally about four years, which means that it is necessary to consider replacing the battery after four years. In addition, when locking the car at night, be sure to turn off the power facilities in the car, especially the headlights. If you forget to turn them off, the battery will die easily the next day.
