What is a car hood
The car hood is the top covering of the car engine compartment, also known as the hood or hood.
The car cover is an open cover on the front engine of the vehicle, usually a large and flat metal plate, mainly made of rubber foam and aluminum foil material. Its main functions include:
Protect engine and peripheral accessories
The car cover can protect the engine and its surrounding pipelines, circuits, oil circuits, brake systems and other important components, prevent impact, corrosion, rain and electrical interference, and ensure the normal operation of the vehicle.
Thermal and acoustic insulation
The inside of the hood is usually sandwiched with thermal insulation material, which can effectively isolate the noise and heat generated by the engine, prevent the paint of the hood surface from aging, and reduce the noise inside the car.
Air diversion and aesthetics
The streamlined design of the engine cover helps to adjust the direction of air flow and decompose the air resistance, improve the force of the front tire to the ground, and enhance the driving stability. In addition, it is also an important part of the overall appearance of the car, enhancing the beauty of the vehicle.
Assisted Driving and safety
The cover can reflect light, reduce the impact of light on the driver, while in the case of overheating or damage to the engine, it can block explosion damage, block the spread of air and flame, reduce the risk of combustion and loss.
The main role of the engine cover (engine cover) includes the following aspects :
Protect the engine : The engine compartment contains the core components of the car, such as the engine, electrical circuits, oil circuits, braking system and transmission system. The engine cover can prevent dust, rain, stones and other external environmental factors from damaging these key components, while playing a buffer role in the event of a collision, reducing the direct impact on the engine and important components .
prevention of accidents : the engine operates under high temperature and pressure environment, there is a risk of overheating or even explosion due to parts loss. The engine cover can effectively block air entry, reduce the speed of the flame, and thus reduce the risk of explosive accidents .
improve aesthetic : the engine cover as an important part of the car, its design directly affects the appearance of the vehicle aesthetic. The carefully designed engine cover harmonizes with the rest of the body to enhance the overall visual effect .
air diversion : Through the streamlined design, the engine cover helps to adjust the air flow, reduce resistance, and improve the stability of the vehicle. The streamlined design can break down the air resistance and improve the grip of the front tires on the ground, which is conducive to the stability of the car .
Pedestrian protection : Some designs such as the spring-up engine cover can spring up in the event of a collision with a pedestrian, supporting the pedestrian and reducing the injury of the pedestrian .
sound insulation and noise reduction : the inner layer of the engine cover can heat and sound insulation, reduce engine noise, and provide a quieter environment .
Protect engine surface paint : prevent paint aging due to high temperature and wear .
Method of opening and closing the engine cover :
When opening, first find the opening handle located on the lower left of the driver's instrument panel and follow the correct steps.
When closing, first remove the early resistance of the gas support rod, after the resistance height of the critical point, release it to free fall and lock, and finally check whether it is closed and locked .
