What is the cause of odor in the car?

Why do cars smell bad?

1. The quality of soundproof cotton. The function of sound insulation cotton is mainly to isolate sound, noise and vibration in the car. Soundproof cotton made of high-quality materials is not only effective, but also does not produce odors such as toxic gases.

However, if the quality of the soundproof cotton filled in the car is defective, it will produce harmful gases to the human body, resulting in odors.

2.Asphalt damping plate problem. The function of asphalt damping sheet is to reduce vibration and noise.

Asphalt can be divided into coal tar asphalt, petroleum asphalt and natural asphalt according to its **, which more or less contain certain toxicity. In addition, asphalt damping sheets have the disadvantages of high weight and narrow temperature range, so most of the toxic gases in vehicles are generated by them.

3.The vehicle is exposed to sunlight for a long time. There is a lot of rubber material in the car. Prolonged exposure to UV rays can also cause the rubber inside the car to melt and produce toxic gases if the car does not have good sun protection.

How to deal with odor in the car?

1.Place sachets and other aromatic items. When there is a peculiar smell in the car, the most convenient way is to put a scented object to mask the smell, but relatively speaking, this method has limitations, and smoking solves the fundamental problem.

If the toxic gas or two odors are incompatible, it will only make the situation worse.

2. Air purifier. Although it can absorb odors to the greatest extent, the cost is high.

3.Through the external circulation device of the car. The main principle of the automobile external circulation device is that the air inside the car and the air outside the car are exchanged with each other, and it can also achieve a certain dust isolation effect, so it is also a more effective way to remove odors.

4.Place activated charcoal. Activated carbon has a strong adsorption force. When the toxic gas in the air body is encountered, it will be adsorbed by it to purify the air body.

5.Go to a specialist repair shop**. There are a variety of reasons why odors in cars can occur. When we can't find it, it is recommended to go to a professional repair shop and let the maintenance personnel handle the repair.

Have you ever wondered why cars smell bad? When driving a car, many car owners find that there is a peculiar smell in the car, but they don't know the cause of the peculiar smell, resulting in no way to start and don't know how to solve the problem. Then to solve the problem, it is necessary to start from the root cause and find out the problem that produces peculiar smells.

1. A large number of plastics, rubber, adhesives and other materials are used in the interior of the car, and these materials will gradually release unpleasant odors during use, which is more serious in new cars.

2. There is a peculiar smell in the car after turning on the air conditioner, because there is a lot of dust in the evaporation box and air conditioning pipe. After the air conditioner is turned on, the air entering the car is cooled through the evaporation box, and during the working process of the air conditioning system, the dust and bacteria in the air will enter the evaporation box and the air conditioning pipe, and after a long time, there will be a peculiar smell when the air conditioner is turned on.

3. Bad car habits will also lead to peculiar smells, some car owners are used to smoking and eating in the car, and rarely clean the interior, after a long time, there will naturally be a peculiar smell in the car.

The reasons for the peculiar smell in the car are: 1. A large number of plastics, rubber and other materials are used in the interior of the car, and the organic solvents, additives and other components in these materials will be gradually released into the car environment during the use of the car, which is one of the main reasons for the peculiar smell in the car, especially in new cars; 2. The peculiar smell caused by the air conditioning filter, many car owners report that when the air conditioner is turned on, a burst of sour smell blows in the face, which is very uncomfortable, but this state will be alleviated after a period of time. In fact, this odor is a sign that the air conditioner filter needs to be replaced, the air conditioner has been decomposed by bacteria and causes mold, and the odor of the air conditioner filter is relieved; 3. The peculiar smell caused by the evaporation box, after replacing the air conditioning filter element, the odor is still not alleviated, this situation refers to the evaporation box, which is caused by mold in the evaporation box, and the replacement of the air conditioning filter can not solve the peculiar smell, which requires the cleaning of the evaporation box and the air duct cleaning of the air conditioner.

<> "The smell of organic oil in the car is mostly due to oil leakage in the engine.

Other possibilities are relatively small, and it is possible that the rubber pipe of the charcoal canister is aging. The rubber tube between the canister and the throttle valve deteriorates as the mileage increases, causing gasoline vapor to leak out. Go directly to the repair shop for more clever dressing.

If the gasoline is overfilled, it is possible to excessively disperse gasoline vapor from the air vents of the through gear, and the gasoline should be added between the lowest and highest scales.

A large number of materials such as plastics and rubber are used in automotive interiors.

If the air conditioner filter causes odors, clean the filter regularly.
