Car cover action
The main role of the car cover (hood) includes the following aspects :
Protect the engine and surrounding parts : Under the hood are the important parts of the car, including the engine, circuit, oil circuit, brake system and transmission system. The hood is designed to effectively prevent the impact of adverse factors such as shock, corrosion, rain and electrical interference on the vehicle, thereby protecting the normal operation of these critical components .
air diversion : The shape of the hood can adjust the direction of air flow around the car, reducing the impact of air resistance on the movement of the car. Through the diversion design, the air resistance can be broken down into beneficial forces, enhance the front wheel grip on the ground, conducive to the stability of the car .
Aesthetics and personalization : The exterior design and material choice of the hood can also affect the overall beauty of the car. Different models and design styles can be reflected through the shape and material of the hood, increasing the beauty and personalization of the vehicle .
sound insulation and heat insulation : the structure of the hood usually contains thermal insulation materials, which can effectively isolate the heat and noise generated by the engine working, providing a more comfortable driving environment .
Automotive cover , also known as the hood, is an openable cover on the front engine of a vehicle, its main function is to seal the engine, isolate the engine noise and heat, and protect the engine and its surface paint. The hood is usually made of rubber foam and aluminum foil materials, which not only reduce engine noise, but also isolate the heat generated when the engine is working to prevent the paint on the hood surface from aging.
structure
The structure of the cover is usually composed of an outer plate, an inner plate and a thermal insulation material. The inner plate plays a role in enhancing rigidity, and its geometry is selected by the manufacturer, mostly in the form of skeleton. There is insulation sandwiched between the outer plate and the inner plate to insulate the engine from heat and noise.
Opening mode
The opening mode of the machine cover is mostly turned backward, and a few are turned forward. When opening, find the engine cover switch in the cockpit (usually located under the steering wheel or on the left side of the driver's seat), pull the switch, and lift the auxiliary clamp handle in the center of the front of the cover with your hand to release the safety buckle. If the vehicle has a support rod, put it into the support notch; If there is no support rod, manual support is not required.
Closing mode
When closing the cover, it is necessary to slowly close it down by hand, remove the early resistance of the gas support rod, and then let it fall freely and lock. Finally, lift up gently to check that it is closed and locked.
Care and maintenance
During maintenance and maintenance, it is necessary to cover the body with a soft cloth when opening the cover to prevent damage to the finish paint, remove the windshield washer nozzle and hose, and mark the hinge position for installation. Disassembly and installation should be carried out in the opposite order to ensure that the gaps are evenly matched.
Material and function
The material of the machine cover is mainly resin, aluminum alloy, titanium alloy and steel. The resin material has a impact rebound effect and protects the bilge parts during small impacts. In addition, the cover can also dust and prevent pollution to protect the normal operation of the engine.
