Car cover action
The main role of the car cover includes the following aspects :
Air diversion : The shape design of the cover can effectively adjust the flow direction of the air relative to the car, reduce the air resistance and improve the driving stability. The streamlined cover design is basically based on this principle .
Engine and surrounding parts : the cover can protect the engine, circuit, oil circuit, brake system and transmission system and other important parts from impact, corrosion, rain and electrical interference, to ensure the normal operation of the vehicle .
heat and sound insulation : the inner layer of the engine cover is usually sandwiched with thermal insulation material to effectively isolate the heat and noise generated by the engine and improve the comfort of the driving environment .
beautiful : The appearance design of the cover also adds a visual sense of beauty to the vehicle and improves the overall beauty .
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 noise and heat of the engine, 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.
Automotive cover failure mainly includes the following situations:
The hood does not open or close properly : this may be caused by a failure of the hood lock mechanism, a problem with the opening line, a blocked locking mechanism, or a failure of the lock body mechanism. Solutions include checking and repairing or replacing the lock mechanism, or using a tool to gently pry open the hood for inspection and repair .
cover jitter at high speed : when some models are driving at high speed, the cover may jitter phenomenon, which may be caused by unreasonable cover materials and design. For example, the 23 models of Changan Ford Mondeo are easy to shake under the influence of wind resistance at high speeds due to the aluminum material and single-lock structure, which brings safety risks to driving .
cover ejection : during driving, the cover suddenly ejection by itself may be due to damage to the hood lock mechanism or short circuit of the related line. At this point you should immediately stop and re-lock the hood, if the problem is recurring, it is recommended to go to a professional repair shop for inspection and repair .
Making an abnormal noise : If you hear an abnormal noise from the hood while driving, it may be due to loose or damaged internal parts. For safety reasons, you should go to a professional auto repair shop as soon as possible for detailed inspection and repair .
Prevention and maintenance recommendations :
Regular check : Regularly check the lock mechanism, opening line and safety mechanism of the hood to ensure that they are working properly.
Keep clean : Clear debris and dust around the locking mechanism and latch to prevent faults caused by accumulation of debris.
professional maintenance : When encountering complex problems, professional auto maintenance personnel should be contacted in time for inspection and repair to ensure safe operation.
