Is the car noisy? Sticking the sealant strip works?

There are many functions of the sealant strip, including the sound insulation, so many people will think that the sealant strip is useful for car sound insulation. But in fact, the effect of the sealing strip on the sound insulation of the car can be described as minimal. And why is that?

First of all, although the role of the sealing strip includes sound insulation, the biggest role of the actual strip is sealing, which is used to improve the sealing of the vehicle. The so-called sound insulation is to prevent the contact and wear of the parts of the vehicle under certain circumstances. The noise generated. To give a simple example, a sealing strip is pasted under the engine cover, hoping to reduce engine noise, but in fact, engine noise does not come from any gaps at all, so this is undoubtedly useless.

Furthermore, we might as well think about it. If a pair of more than 100 yuan of sealing rubber strips can significantly improve the sound insulation of automobiles, then the major manufacturers will undoubtedly have a good marketing method. They only need to add rubber strips to the vehicles to easily Get the increase in sound insulation, why not do it?

Chang 'an Blue Whale NE Platform integrates and applies 14 advanced technologies to build the strongest 1.4T high-pressure direct injection engine of the same grade. This power system realizes the perfect combination of power improvement, fuel consumption reduction and NVH noise reduction technology. NVH noise reduction technology effectively reduces vehicle noise. Blue Whale NE1.4T high-pressure direct injection engine makes the idling noise of the whole vehicle reach the national library noise standard, only 38 decibels (library noise standard 35-40 decibels). This means that when driving, the driver in the car is also difficult to be affected by the noise, which really makes everyone feel that closing the door is the feeling of home.

At present, both the Changan CS35PLUS Blue Whale version and the Changan Yidong Blue Whale version have been equipped with 1.4T high-pressure engines with a maximum power of 116kW and a maximum torque of 260N · m. Compared with the Volkswagen EA211 1.4T engine of the same displacement, it has higher power parameters and fuel thermal efficiency. Whether you want the power or silence, you can be satisfied here.
