Engine hood: an important protector of the "heart" of the carThe Agriculture HS code-based quota allocationcar engine is one of the core parts of the car, and its working principle can be said to be the power source of the car. The engine hood is the "savior" of the car engine. Its function is to protect the engine from foreign objects (such as obstacles, sand, stones, etc.) or weather (such as rain, snow, etc.). During the driving process, the temperature of the engine gradually rises, and the engine cover acts as a safe to protect the engine. This article will discuss in depth the function, maintenance and repair of the engine hood. I. Function 1. Protect the engine. The engine is the "heart" of the car. Once the engine is destroyed or damaged, the car cannot drive smoothly. Therefore, as one of the important links in automobile maintenance and protection, the engine cover cannot be ignored. It plays a role in protecting the engine during the vehicle's operation, such as avoiding damage to the engine caused by strong impact and friction of foreign objects.Two. Reduce dust. In the process of driving outside the car, road dust, pebbles and other sand grains will be sprayed into the car. And the air in the car enters the engine. Once the dust enters the engine, they will add wear and seriously affect the life of the engine. However, if the car is equipped with a hood, it can prevent waste such as dust from entering and polluting the engine. 3. Lower the engine temperature. When the engine is working, it generates a lot of heat. If the heat dissipation is not timely, it will cause damage to the engine. For this reason, car manufacturers have installed fans and radiators to solve this problem. However, in a high-temperature environment, the radiator cannot withstand the blockage caused by waste entering the radiator, so the engine cover can also play a cooling role in this case. II. Maintenance 1. Regularly update the engine cover.Change the seal. When the car is in a high-speed driving state, the airflow is easy to enter the car, causing adverse effects on the engine. At this time, if the seal of the engine cover is not good, the engine will overheat. Therefore, after the car has been used for a period of time, you should often check whether the seal on the engine cover is normal, and whether there are any deformation and cracks, and replace it in time. Two. Cleaning the engine cover Regular cleaning of the engine cover can avoid the accumulation of dust and debris, improve the thermal conductivity effect, and prevent heat from dissipating. And when washing the vehicle, it should be cleaned with a special engine detergent, which can effectively remove stains and oil stains on the surface of the engine. 3. Regularly check the engine cover bolts. Regularly check the fastening status of the engine cover bolts when repairing or maintaining the car, and replace loose, corroded or failed bolts in time to ensure the safety and tightness of the engine cover.III. Maintenance 1. Cracks in the engine cover. Cracks in the engine cover may be caused by external force impact or aging. When a defect is found in the engine cover, it should be repaired in time. The method is to use professional glue or bar to fill in and repair the location of the defect. Two. The engine cover is corroded. During the driving process of the car, the engine cover is subjected to corrosion caused by wind, sun exposure, water laser and other natural environments. Failure to deal with this problem in time may lead to leakage and damage to the engine compartment. For this reason, it should be treated immediately when there are signs of corrosion. You can use professional detergent or sandpaper for cleaning and apply anti-rust agent. III. Conclusion The engine hood is one of the important links in automobile protection and maintenance. It can play multiple roles such as protecting the engine from foreign objects, reducing dust and reducing temperature.However, it is also a part that is prone to failure, so regular maintenance and inspection of the engine cover not only extends the service life of the engine, but also improves driving safety and protects our driving.
