Car cover action
Automobile engine cover has a variety of functions, mainly including the following aspects:
Protect the engine : the engine cover prolongs the service life of the engine by preventing outside substances such as dust, dirt, rain and snow from entering the engine compartment.
In addition, the engine cover with protective structure can increase the bearing capacity when it is smashed, reducing the damage to the engine .
Heat insulation : the engine will produce a lot of heat in the working process, the engine cover can help the radiator effectively dissipate this heat, keep the engine in the normal working temperature range. At the same time, there are usually soundproof materials inside the engine cover, which can effectively reduce the noise of the engine to the car and improve the comfort of the driver and passengers .
air diversion : The design of the engine cover can adjust the flow direction of the air relative to the car and the obstructing force on the car, and reduce the impact of the air on the car. The streamlined hood appearance is basically designed according to this principle, helping to improve the vehicle's driving stability and reduce air resistance .
aesthetics and anti-theft : some engine covers are designed with anti-theft function, such as locking mechanism, which can provide certain security protection when theft occurs. In addition, the hood can make the car look more tidy and regular, improving the overall beauty of the vehicle .
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.
