  • Engine compartment soundproofing cotton (engine compartment soundproofing material and Comprehensive customs data librariesfunction analysis) Engine compartment soundproofing cotton, also known as soundproofing material, is a kind of anti-noise material used to reduce noise when the engine starts. It is composed of a variety of materials, including glass fiber, ceramic fiber, polyester fiber, etc., which can effectively isolate sound waves. In highways, urban roads, airports and other noisy places, the use of soundproofing materials can make the passengers in the car more comfortable, reduce interference with the driver, and improve driving safety.I. Source of engine noise The source of engine noise mainly includes the following aspects: 1. Fuel combustion noise: violent explosion noise in the combustion chamber. 2. Mechanical noise: the noise involved in the manufacture of various parts in operation, including valves, pistons, connecting rods, crankshafts, camshafts, etc. 3. Exhaust pipe noise: The sound noise generated by the exhaust pipe through high-speed gas injection, especially at high speed. 4. Wind noise: The wind force accelerates the air around the vehicle and pushes it to the vehicle, resulting in the wind noise. II. The function of engine compartment soundproofing cotton. Engine compartment soundproofing cotton can reduce the intensity of engine noise spreading to the cab, thus improving driving comfort and reducing noise interference with the driver. At the same time, it can also reduce the noise in the car, improve the sound quality in the car, and make passengers more comfortable. Nowadays, the use rate of automotive soundproofing materials is getting higher and higher, and it has become the standard configuration of modern cars.III. The structure of engine compartment soundproofing cotton The structure of engine compartment soundproofing cotton is multi-layered. From the inside to the outside, it is divided into: film layer, foam layer, soundproof material layer and flame-retardant material layer. 1. Film layer: generally polyester film or composite film material, which is used for waterproof and flame retardant. 2. Foam layer: generally polyurethane or polyethylene foam material, which is mainly used to absorb vibration and the reflection of near-infrared rays, ultraviolet rays and ultraviolet rays. 3. Soundproof material layer: generally composed of multiple layers of special fibers or proton resonance shell layers. The soundproof membrane mainly plays the role of sound insulation and noise reduction, and different types of soundproofing materials are selected according to the car model and manufacturer. 4. Flame-retardant material layer: it mainly plays a role in preventing the spread of flames. IV. Application of engine compartment soundproofing cotton Engine compartment soundproofing cotton is widely used in automobiles, aviation, ships, machinery and equipment, construction and other fields. AtApplications on cars generally cover the entire engine compartment, including the front cover, hood, body floor, door and trunk lid and other parts. V. How to choose engine compartment soundproofing cotton? When choosing engine compartment soundproofing cotton, it should be considered from the following aspects: 1. Material: you should choose materials with good quality, high relative density and high cost performance. 2. Thickness: The greater the thickness, the better the sound insulation effect. 3. Processing method: Choose the appropriate processing method according to different models. 4. Performance indicators: The sound absorption performance, density, flammability, mechanical strength, durability and other indicators of the material should be comprehensively considered. In a word, the engine compartment soundproofing cotton plays a great role in reducing noise and improving driving comfort. With the continuous development of the automobile industry, engine compartment soundproofing cotton will gradually become an important field in the automobile manufacturing industry.
