In simple terms, the engine is an energy conversion mechanism, which converts the thermal energy of the automobile or diesel or natural gas into mechanical energy by burning gas in the cylinder to expand and push the piston to do work. Therefore, the engine is prone to noise and heat when working. In order to absorb cabin heat, reduce noise and beautify the cabin environment, an engine sound insulation and heat insulation hood needs to be installed on the automobile engine hood. It is urgent to develop a car heat insulation hood structure with sound insulation effect to facilitate market promotion and application.

The sound insulation board is made of foamed silicone board, which can block the noise generated by the engine. The sound insulation groove further weakens the noise, improves the sound insulation effect of the heat insulation cover, reduces the noise to a level that meets the noise standard, avoids the noise generated by the engine from causing noise pollution to the surrounding environment, and improves the comfort of the user. The technical effect solves the problems that the sound insulation effect of the car heat insulation cover structure is poor, the noise generated by the engine causes noise pollution to the surrounding environment, reduces the comfort of the user, the heat insulation effect is poor, and it is easy to spontaneously combust when running at high temperature for a long time, which poses a safety hazard.
