Вкладыш для подавления шума двигателя Caterpillar 3967698

An Engine Sound Suppression Liner is installed on the underside of the engine hood within the engine enclosure to dampen sound and provide thermal insulation. It serves to absorb sound waves and vibrations generated by the engine. It consists of multiple layers of sound-absorbing materials, such as insulation, that are sandwiched between a protective outer layer and an adhesive backing. It is strategically placed within the hood and guard to dampen sound waves and minimize their transmission.Attributes:• Provides high vibration damping capacity and toughness• Withstands the demanding conditions encountered during operation, including temperature variations, moisture exposure, and mechanical stressApplications:An Engine Sound Suppression Liner acts as a barrier between the sound suppression sheet and the supporting structure of the hood and absorbs the sound energy. It reduces the propagation of noise by converting sound energy into heat energy through the friction and resistance of the sound-absorbing materials.
