Is the inner lining of the Audi A6 engine guard a soundproof plate or a thermal insulation plate?

1. Audi A6 makes the whole car soundproof, ranging from 2000 to 4000 depending on the material.Sound insulation technology of Audi A6: (1) The interior panel of Audi A6 is made of TEAC sound-absorbing cotton, which has excellent sound-absorbing and heat insulation function, which can effectively attenuate the medium and high-frequency noise in the car, improve driving comfort, isolate heat transfer, and save air energy consumption.

2. The bottom of the vehicle. The thermal insulation plate of the Audi A6 is located at the bottom of the vehicle, installed under the engine compartment of the vehicle or at the front of the vehicle chassis. Its main function is to reduce engine noise, heat conduction and vibration transfer to the vehicle, providing a quieter and more comfortable driving environment.

3. Audi A6 adopts a variety of soundproofing materials, including high-density sound-absorbing cotton, soundproofing membrane, etc., which are arranged in various parts of the body to effectively isolate external noise. The door sealing is also very good, effectively blocking the entry of external noise.

Is it necessary for NIO to install an engine insulation board?

1. Let's talk about thermal insulation cotton. Thermal insulation cotton can not only separate the temperature, but also minimize the noise of the engine, giving you the best driving experience. Therefore, it is still necessary to add a piece of heat-insulating cotton. That's not called heat-insulating cotton.It should be soundproof cotton. Its function is nothing more than to reduce engine noise and improve the driving experience.

2. It is still necessary to install the engine guard. There are many advantages of power-powered installation guards. In daily driving, the wheels will roll up debris on the ground, such as sludge, rainwater, etc. These things may cause some corrosion to the exposed parts of the car chassis. In order to protect these parts, engine shields can be installed to avoid the loss of these parts.

3. We are not professionals in this thing. Personally, I think it is still necessary to pretend! Digital Xu Xiake: This thing is a health care product. It can't be eaten to death, but it has absolutely no effect.

4. It is necessary to install the engine cover plate, on the one hand, to keep the engine compartment clean, and on the other hand, to protectSome wire harnesses in the engine compartment can also reduce the noise generated by the engine during operation.

Where is the Audi a6 heat insulation plate

1. Hello, the top of the gearshift mechanism on the 2017 Audi a6 chassis is equipped with soundproof cotton. This soundproof cotton not only has the effect of sound insulation but also has the function of heat insulation. . It can be replaced separately.

2. Before that, in fact, there have been many spontaneous combustion accidents of the new Audi a6 all over the country, and the fire position of the car is on the exhaust pipe insulation plate behind the engine compartment, and many car owners did not get the equipment of the car 4s store when they went to the car 4s store for relevant inspections. Body explanation.

3. Audi's lighting is absolutely good.When it is installed, remove it all. When it is installed, remove it all and start to apply the film. The whole car is 1800. The heat insulation is very good, and the clarity is also very good! Start to apply the film, the whole car is 1800.

4. After dismantling, the ceiling should be cleaned up, all kinds of wires should be sorted out, the front seats should be flattened, and the ceiling should be pulled out through the back door. Then the fabric is perforated. At this time, you must be careful not to cut too much, otherwise the part of the ceiling will be exposed and it will be ugly. Finally, put on the glue, and then put the removed parts on it after it is firmly glued.
