He hood of automobile engine is generally made of rubber foam cotton and aluminum foil. When reducing the engine noise, it can isolate the heat generated by the engine at the same time, effectively protect the paint on the surface of the hood and prevent aging.
Hood function:
1. Air diversion. For high-speed moving objects in the air, the air resistance and turbulence generated by the air flow around the moving objects will directly affect the motion trajectory and speed. Through the shape of the hood, the flow direction of the air relative to the vehicle and the blocking force on the vehicle can be effectively adjusted to reduce the impact of the air flow on the vehicle. Through diversion, the air resistance can be decomposed into beneficial force. The force of the front wheel tire to the ground is high, which is conducive to the driving stability of the vehicle. The appearance of the streamlined hood is basically designed according to this principle.
2. Protect the engine and surrounding pipeline fittings, etc. Under the hood, it is an important part of the car, including engine, circuit, oil circuit, braking system, transmission system and so on. Critical to the vehicle. By improving the strength and structure of the engine cover, it can fully prevent the adverse effects such as impact, corrosion, rain and electrical interference, and fully protect the normal operation of the vehicle.
3. Beautiful. Vehicle exterior design is an intuitive embodiment of vehicle value. As an important part of the overall appearance, the hood plays a vital role in pleasing the eyes and reflecting the concept of the overall vehicle.
4. Auxiliary driving vision. In the process of driving the car, the reflection of the front line of sight and natural light is very important for the driver to correctly judge the road and front conditions. The direction and form of reflected light can be effectively adjusted through the shape of the hood, so as to reduce the impact of light on the driver.
