Description

technical field

[0001] The invention relates to a protection facility, in particular to a fire wall with sound insulation and heat insulation performance for automobile engines. Background technique

[0002] As we all know, in the field of automobile industry, the engine occupies a very important position. It is an important core component of any type of automobile, so the development of the engine also promotes the development of the automobile industry. With the development of science and technology and the continuous improvement of human needs, automotive engines have also experienced a long development journey, and their main development trend is to move towards the goal of high power and low displacement. However, high power and low displacement mean that the combustion efficiency of the combustion medium (mainly gasoline and diesel) in the engine should be improved, and the improvement of combustion efficiency means that the noise and temperature of the engine will inc...

Embodiment Construction

[0013] Such as figure 1 with figure 2 As shown, the vehicle engine firewall with sound insulation and heat insulation performance of the present invention includes a wall panel 1 whose shape is consistent with the shape of the vehicle engine, and the wall panel 1 is made of rubber material, and the commonly used rubber material is fire-resistant rubber. The outer surface of the wallboard 1 is covered with a polyurethane foam layer 2 . In this embodiment, the shape of the wall panel 1 is similar to the shape of a men's top hat, the top part of the hat is used to cover the engine, and the brim part of the hat is used for fixing between the engine cover and the vehicle frame.

[0014] In order to reduce the heat conduction to the wallboard, slow down the rubber aging speed, and increase the service life of the firewall, in this embodiment, the inner surface of the wallboard 1 is also covered with a layer of polyurethane foam layer 2 .

[0015] When in use, the vehicle eng...
