Why don t the 15 Bora models leave the factory without sound insulation panels?

Because Bora has reduced this configuration, there will be a discount on the cost, and when you go to the 4S store for the first insurance, it will also be marketed, so that you can install soundproof cotton and earn the installation fee.

Hello, why is it possible for Bora to appear? There is no cabinet so as not to buy a lot of vehicles now, and the revolutionary age has been canceled at the time of leaving the factory, not because the technology in the amount is getting better and better, resulting in a decrease in noise, and more manufacturers have canceled this soundproof cotton, for his role in that channel, I hope I can help you.

The secret of buying a car is to develop its strengths and avoid weaknesses, every year there are a large number of new cars emerging in the car market, manufacturers do not stop making a fuss about various performance configurations, often in the cost and selling points of the game, prospective owners can choose from it to meet their own requirements of the car, speaking of the evolution of the Bora is indeed a vivid game, as the popular evergreen tree, each upgrade of the Bora is considering two aspects: life and performance, life refers to the configuration in addition to the power control system, When it comes to the indispensable configuration of the owner in daily life, such as interior, disc player, seat, sound insulation, etc., performance is the core power control safety of the car.

The 21 Bora automatic comfort version of the back door does not have soundproof cotton because the trunk has no effect on sound-absorbing cottonIt may be because the sound-absorbing cotton is misplaced, if there is noise in the car, first find out the noise **, and then put the sound-absorbing cotton in the noisy position, the engine will produce noise during the working process, mainly through the front fender, engine cover, firewall and exhaust pipe into the car.

In addition, when the car is driving, the chassis will vibrate, and the sand and gravel on the road surface will also have an impact on the chassis of the car, which is the main cause of road noise generated by the car. The most direct way to eliminate noise is to use soundproof cotton, which can also be generated by the friction between the tire and the ground during driving. The magnitude of tire noise needs to be determined according to the road conditions of the car and the tire trajectory of the car.

If the car is driving on a road with poor road conditions, the noise of the car will be greater, in addition, the car will also produce noise during driving, the wind from the outside world will enter the car through the sealing resistance of the door to produce noise, the faster the car drives, the louder the noise will be, and the installation of soundproof cotton in the car will reduce the noise in the car. It is more suitable to install high-efficiency soundproof cotton noise reduction.

If the hood does not have its own insulating pads, it is useful to install insulating cotton. It protects the painted surface of the canopy and also has the function of sound insulation and sound absorption.

Another function of acoustic insulation is thermal insulation, which reduces the amount of heat transferred to the surface of the hood when the engine is running. Vehicles equipped with hood acoustic insulation foam will hardly produce white fog on rainy days. In rainy days and winter, due to the large temperature difference between the outside temperature and the engine, coupled with the erosion of the engine hood by rain, the oxidation of the paint surface will be accelerated.

Insulation cotton can protect the paint surface of the hood to a certain extent.

Noise in the car is usually ignored by the owner. Since the mainstream models sold in China are still low-end models, and many domestic cars have increased the height and strength of the suspension system in order to "fit China's road conditions", more stability and noise will follow. Of course, poor material selection and assembly quality (especially for economic models), old starters, and unfit air aerodynamics are also one of the reasons for the noise of domestic cars.

Even imported cars with good sound insulation may become the low-to-medium level of friendly models in the same country because of the "cost reduction" of the Chinese version.

Millions of car purchase subsidies.

The engine guard plate should be added, now it is an all-aluminum engine, and the oil pan is also aluminum, the guard plate can effectively block the invasion of foreign objects splashed on the road, and prevent property damage, which is worth installing; Soundproof cotton, whether it is installed or not seems to be of little help to reduce noise.

The lower engine guard can be added, and as for the sound insulation panel, it can be added if it feels noisy.

The sound insulation of the original car is average. When I bought a new car, I was reluctant to drive violently because of the run-in, and I was reluctant to let him go on a bad road, so the noise had not yet been shown. You'll know if you open for a long time. It's noisy in the car when you run fast.

But don't worry, the models at this level are all about the same, and they are basically practical. If you don't drive irritable, you can find a professional soundproofing shop in the later stage, focusing on the soundproofing of the chassis, the soundproofing of the trunk, and the soundproofing of the four wheels. Doing a good job can significantly reduce road noise.
