What is the reason for the loud noise of the car? How to solve it

Parts failure: In addition to its own factors, if noise occurs, it may be a fault of the parts. Therefore, if you find that the engine noise is getting louder and louder, you should immediately go to the repair shop for repair.

Then, at this time, it is necessary to install soundproofing materials from doors, fenders, fenders and other parts to reduce noise. Excessive tire pressure will also cause resonance between the tire cavity and the road surface, resulting in increased tire noise.It is also important to maintain normal tire pressure.

The main reasons for high car noise are: engine noise: carbon accumulation, damage to shock absorber parts, aging seal; tire noise, road noise, wind noise, chassis noise, etc. If it is caused by engine noise, clean up the accumulated carbon and replace the shock absorbers and seals. It is recommended that the owner check one by one to further solve the problem.

The noise of the car is caused by these reasons after driving for a long time. Do both new and old drivers know? With the development of science and technology, there are more and more kinds of cars. But no matter how expensive the car is, all kinds of problems will occur after driving for a long time, especially the noise will gradually increase.

The car has been driving for a long time, making a lot of noise and vibration. How to improve it? With the improvement of the driving age of the car, various parts of the car will have different degrees of aging, and then there will be some "unusual sounds" in the car.The so-called abnormal sound is the sound made by auto parts in the state of friction after normal aging. Several common causes and solutions of abnormal sounds.

Solution: In this situation, it is necessary to check and replace the intake and exhaust pipes to avoid noise. The fuel quality is poor and the engine noise is loud. When poor-quality fuel is used, the combustion condition in the engine will deteriorate, causing the engine to vibrate violently and produce noise.

How to reduce car noise?

Many cars also have soundproof cotton in the engine compartment, which can not only reduce the noise of the engine, but also has other wonderful uses, such as heat insulation and preventing the aging of the cover paint. Choosing to install soundproofing materials, such as soundproofing cotton, soundproofing blankets, etc., can effectively and quickly improve the quietness of the car. Because the cost is not high, it is also the method chosen by many car owners.

The ways to reduce car noise are: replace silent tires and use well-known brands of fully compound oil (which can effectively reduce engine noise) to maintain appropriate speed, drive at a uniform speed, and remove all additional parts on the exterior of the car to soundproof the whole car.

The seal can fill the gap and put the door, the rear box cover is closely combined with the car body to enhance the airtightness of the car, effectively reduce the air noise entering the car, and the noise in the car is naturally less. The seal also has the effect of blocking dust and heat.

The noise in the vehicle is mainly caused by the three aspects of engine noise, wind noise, and tire noise. Noise reduction should start from these three points: reduce engine noise.

The way to reduce engine noise is to paste sound-absorbing material under the hood. How to reduce wind noise: install seal + door soundproofing. Methods to reduce tire noise: door, door edge, upper part of the wheel arc, wing plate and chassis are pasted with soundproof materials; replace comfortable tires; front and rear wheel covers are pasted with soundproof cotton curves.

Car noise reduction method Reduce engine noise, and put sound-absorbing foam under the engine cover. Engine noise is transmitted into the cab through the vibration of the front wing plate, hood and exhaust pipe.

What are the types of car noise

Engine noise: The vehicle engine is a source of noise, and its noise generation varies with the engine speed (mainly through: front leaf plate, hood, fire barrier, row Tracheal generation and transmission).

Tire noise Tire noise is caused by the friction between the tire and the road surface when the vehicle is driving at high speed. The size of the tire noise depends on the road conditions. The worse the road conditions, the greater the tire noise. In addition, there is a big difference between the asphalt road surface and the concrete road surface (mainly through: chassis, trunk, front leaf plate, front wheel arc Generate and transmit).

Engine noise: The vehicle engine is the source of noise, and its noise is caused by the different engine speed. It is mainly caused and transmitted through the front wing plate, hood, firewall and exhaust pipe.Road noise: Road noise is the noise caused by wind cut and chassis vibration when the vehicle is driving at high speed.

Car wind noise is the main noise of the car driving. Wind noise is the noise caused by the pressure change caused by the separation of the airflow when the car body hits the wind, and the noise caused by the interaction between the airflow around the body gap intake and the car body or the noise caused by airflow resonance.

What kind of car noise 1 engine noise. In addition to the mechanical sound made by the engine body, it also includes the noise of the intake system, that is, the high-speed gas enters the cylinder through the air filter, intake pipe and valve. During the flow, a strong pneumatic noise will be produced.

Engine noise The first place is naturally the abnormal noise of the engine, which is also the most obvious one in the car noise. Engine noise is divided into cold car noise and hot car noise.The abnormal sound of the cold car refers to the strange sound from the engine compartment when the car is started, which automatically disappears after the car is heated.

What kind of noise does the car have

1. Road noise: Road noise is caused by the wind cutting in to form noise and driving chassis vibration when the vehicle is driving at high speed. In addition, the sand and stone impact on the road will also produce noise on the chassis of the car, which is the main road noise. Source (mainly through: four doors, trunk, front leaf plate, front wheel arc generation and transmission).

2. Road noise: Road noise is the noise caused by wind cut and chassis vibration when the vehicle is driving at high speed. The impact of gravel on the road on the chassis may also produce noise, which is the main source of road noise. It is mainly caused and transmitted by four doors, trunk, front wing plate and front wheel arc.

3. Tire noise Tire noise is caused by the friction between the tire and the road surface when the vehicle is driving at high speed. The size of the tire noise is determined by the road conditions. The worse the road conditions, the greater the tire noise. In addition, there is a big difference between the asphalt road surface and concrete road surface (mainly through: chassis, trunk, front leaf plate, front Wheel arc generation and transmission).

4. What kind of car noise 1 Engine noise. In addition to the mechanical sound made by the engine body, it also includes the noise of the intake system, that is, the high-speed gas enters the cylinder through the air filter, intake pipe and valve. During the flow, a strong pneumatic noise will be produced.

5. Many people always feel the noise from the bottom when driving, and there are also car owners who have someone or a mouse in the bottom of the car. In fact, most of them are abnormal seats., there will be some knocking or rubbing sounds when the screws of the mounting base of some seats are loose. These can be repaired by yourself as long as you find the right position.

The reason for the loud noise of the car

The engine accumulates carbon. Too much carbon accumulation in the engine will lead to an increase in rotational speed, and the noise produced will naturally be loud. Solution: We can choose to run high-speed or genuine fuel. If it's too serious, it's better to go to the repair shop to clean it up.

Reasons for the loud noise of the car: engine noise: divided into carbon accumulation, damage to damping parts, and aging of the seal. This is the most obvious noise of the car. Engine abnormal noise is divided into cold car abnormal noise and hot car abnormal noise. The abnormal sound of the cold car refers to the abnormal sound from the engine compartment when the car lands, which automatically disappears after the car is hot.

The following are the reasons for the loud noise of the car:, Weather reasons: The cold weather causes the engine idling speed to increase. If the engine of the cold car always maintains a high speed, you will feel that the engine sound becomes louder. This situation is a normal phenomenon. There is no need to worry. Almost all cars will have increased engine idling speed in winter. When the car gets hot, the idling speed will drop.

The reasons for the loud noise of cars are: aging or loose anchor glue. Anchoring rubber is a rubber block laid between the engine and the frame. Its function is to reduce the vibration and buffering of the engine when it is working, and to give full play to the effect of fixing the engine. When these rubbers age or relax, they will produce engine vibration, and the faster the speed, the louder the vibration sound.
