Motivation insulation cotton (it is HS code-based re-exports in free zonesa good idea to improve the thermal insulation effect of vehicles and install engine thermal insulation materials) With the increasing popularity of vehicles, more and more people choose cars as the main means of transportation in daily travel. In the process of vehicle operation, the engine is one of the most important parts. The working principle of the engine is generally to rely on burning gasoline or diesel to generate power, which converts the mechanical kinetic energy on the car into the power of the vehicle. However, the engine will produce a very high temperature when it is working, which will affect the whole vehicle. Therefore, in order to improve the thermal insulation effect of the vehicle, installing engine thermal insulation material is a better solution. 1. Why does the engine need to be insulated? Engine thermal insulation cotton is a thermal insulation material located outside the engine shell, which is used for sound insulation and insulation. When the vehicle is running, the engine will constantly burn for a short time, resulting in exhaust gas and heat.These exhausts and heat will accumulate around the engine and in some areas under the hood, causing the vehicle to overheat, which will further affect the driver's driving comfort. Therefore, the main function of engine insulation cotton is to keep these high-temperature exhaust gas and heat away from the cockpit and keep the in-car environment dry and the temperature suitable. 2. Advantages of engine insulation cotton. Installing engine insulation cotton has the following advantages: First, isolate noise. The engine will make a lot of noise when working, which will not only put psychological pressure on the driver, but also affect the rest of the passengers in the car. Installing engine insulation cotton can effectively absorb sound noise and reduce the impact of in-car noise on drivers and passengers. Secondly, reduce fuel consumption. During the operation of the vehicle, a large amount of heat will be generated due to the work of the engine, which will raise the temperature in the car.At this time, the air conditioning system in the car needs to consume more fuel to keep the environment in the car suitable. By installing heat-insulating cotton, the temperature in the car can be effectively controlled, thus reducing the fuel consumption of the in-car air conditioning system. Finally, protect the engine. Over time, the parts of the engine will be severely worn and aged. Installing thermal insulation cotton can reduce the impact of heat on the engine, thus prolonging the service life of the engine. 3. How to choose the right engine insulation cotton? When choosing engine insulation cotton, it is necessary to choose according to the brand, model, power, displacement and other characteristics of the vehicle. First of all, the appropriate insulation cotton thickness should be selected according to the actual situation of the vehicle. Generally speaking, the higher the power of the vehicle, the higher the thickness of the required thermal insulation cotton should also increase accordingly; secondly, high-quality materials should be selected for manufacturing to ensure that it has strong thermal insulation performance and has the characteristics of high temperature resistance, corrosion resistance, vibration resistance and so on.4. How to install the engine insulation cotton? The installation of engine insulation cotton requires technical support, which needs to be carried out under the guidance of a special maintenance station or technician. In the process of installing the engine insulation cotton, you need to open the engine cover first and clean up the dust and grease on the engine surface. Then, according to the structure of the engine, cut the parts that need to be covered, apply thermal insulation cotton, and use special materials to seal it to ensure that it can be used for a long time. 5. Summarize that engine insulation cotton is an important equipment that can effectively improve the thermal insulation effect of vehicles. By installing engine insulation cotton, it can reduce noise in the car, reduce fuel consumption, protect the engine and other multiple advantages. In the process of selecting and installing engine insulation cotton, you need to pay attention to choosing the right material and thickness, and in the professionalOperate under the guidance of the personnel to ensure that the engine insulation cotton can be used for a long time to provide better comfort and safety for car travel.
