What does Brother Daewoo mean by telling Fortune _ Daewoo?

Why is the noise of cars getting louder and louder?

1. Did not change the oil on time.

Many car owners are very busy and occasionally forget to check and change the oil regularly. They think the car is ok and then drive. I don't know that poor oil condition will lead to poor internal lubrication of the engine and noise.

Therefore, in order to create a more comfortable driving environment for yourself and your family, no matter how busy you are, remember to check regularly and go to the 4S shop to change the oil on time.

2. There is no regular cleaning of carbon deposits.

Being in a city, traffic jams and idling on the road are commonplace, and driving for two or three kilometers also happens from time to time. However, these bad car habits will cause carbon accumulation inside the engine, and if it is not cleaned for a long time, it will lead to car jitter, weak power and loud noise.

It is difficult to avoid engine carbon deposition, so it is necessary to go to 4S shop for cleaning regularly.

3. Poor fuel quality

Some car owners insist on the principle of energy saving and use inferior fuel, but the inferior fuel often can't be fully burned, and even cause the engine to vibrate violently.

After a long time, the noise will naturally get louder and louder, and the engine will "hang up" when it is serious. So the fuel must be of good quality!

4. Engine bracket aging

The engine and the car body are connected through the engine bracket, which can effectively buffer and suppress the engine vibration and help reduce the noise and vibration.

If it is found that the noise of the car increases obviously in use and the whole car shakes, it is probably caused by the aging of the engine bracket. At this time, it is necessary to go to the 4S shop to test and replace the engine bracket in time.

Reason two. Other noises

In addition to engine noise, tire aging, exhaust pipe corrosion and shock absorber damage are also the causes of noise during driving.

1. Tire aging

Everyone knows that tires are rubber products. No matter what brand you use, it will age, harden and become less elastic after long use. The noise of aging tires driving on the road can be imagined.

2. Exhaust pipe corrosion

Do people simply think that the exhaust pipe is only used to discharge gas? Don't! The main function of TA is to make the whole exhaust system flexibly connected (in terms of relatively rigid connection, it means that the relative connectors are both binding and have a certain degree of relative displacement), so as to achieve the purpose of shock absorption and noise reduction.

However, the exhaust pipe is always exposed, and long-term accumulation of water and rust inside will inevitably produce leakage points and increase exhaust noise.

The shock absorber is damaged.

"Shock absorber", as its name implies, is used to reduce the vibration of the car body. When the shock absorber is damaged, the vehicle is unstable and the noise is not great, please make up for it yourself.

Summary: The more the car drives, the louder the noise, which is related to the aging of the internal parts of the car body and many bad car habits.

Keeping good car habits and going to the 4S shop for inspection and maintenance on time are effective ways to ensure that your car can accompany you for a long time.
