At a time value of 315, the car industry has made several issues on the quality of the car to help consumers and friends to question and defend their rights. Today is the last issue of this topic. Let’s talk about the smell of the car.
I believe that my friends often encounter odors in the car during the daily use of the car. In fact, this phenomenon is very common. Whether it is a new car that has just been purchased or an old car that has been used for many years, there may be odor inside the car, but the causes are not the same, and the effects on the human body and the treatment methods are also different. Let’s take a closer look.
Generally speaking, a large number of adhesives, rubber, and other materials are used in the assembly process of the vehicle. At the same time, some of the cheap models also use a lot of plastics and fabrics with poor quality. These new materials contain many volatile solvents and additives. After sun exposure or long-term non-ventilation, it is easy to release substances harmful to the human bodies such as toluene and formaldehyde, and these substances also bring irritating odor, which is the source of new car odor.
This situation is ubiquitous, and this is more common for entry-level models, but for consumers, this situation does not have to worry too much. Under normal circumstances, we only need to open the window to ventilate, after a period of time, the harmful substances will naturally dissipate, and then we can use it with confidence.
02 Wind odor
In addition to the smell of new cars, car odor is also a common type, and the main reason for the wind odor is that the air conditioning filter has a problem.
The air-conditioning filter element is a filter device through which the air passes from the outside to the car. Similar to the air filter element, the air filter element is folded in paper shape and is generally placed in the front foot position. It can filter out some of the particles in the air and purify the air. However, when the air-conditioning filter element has not been replaced for a long time, the filtering effect will be greatly reduced, and dust often enters the car, causing a feeling of poor breathing.
On the other hand, if the air conditioning in the summer has a musty smell, it is also a problem encountered by some friends. The reason is that the air conditioning air supply duct is moldy. The reason for this phenomenon is that the air conditioner and the engine are closed at the same time in the summer, and the cold air is likely to form moisture in the air supply duct, and it is often easy to breed bacteria to produce odor. To avoid this kind of situation, we only need to turn off the air conditioner compressor before the flameout, and use the external circulation mode to let the hot air enter the air supply duct, and try to keep the air supply duct dry.
03 NVH material asphalt
Asphalt has good vibration and sound insulation effects. It is widely used on automobiles to solve the NVH problem of automobiles. At present, more than 90% of China’s models can see asphalt, and even more popular in high-end luxury brands.
However, on October 27, 2017, the list of carcinogens published by the World Health Organization’s International Agency for Research on Cancer showed bitumen. At the same time, car odors and car safety issues pushed it to the forefront. In fact, we don’t have to talk about asphalt color change. After all, quantitative change can cause qualitative change. Domestic, German, EU, etc. have not included it in the ban list, so it is not terrible to have asphalt in the car. However, if the asphalt smell appears in the car and does not dissipate for a long time, then it may be that the asphalt is used too much, so we need to be vigilant.
Written in the end: According to the truth, in the case of reasonable materials and technical clearance, car odor can be quickly removed and avoided, and if the irritating smell in the car is maintained for a long time, then we should be vigilant. Look for sources of odors and check with 4S stores to protect their legitimate rights and interests.
