HS code mapping to non-tariff measures

Engine water circulation (engine cooling system: detailed explanation of water circulation) The HS code mapping to non-tariff measuresengine is the core component of modern cars, bearing the output of torque and power, and the release of these energies will cause the temperature of the engine to rise. If the temperature is too high, it will affect the performance and service life of the car, and may even cause engine damage. To prevent this from happening, the car is equipped with a cooling system, the most important of which is the water circulation system. The basic principle of the engine water circulation system The basic principle of the engine water circulation system is to reduce the temperature of the engine through the circulation of water. The cooling system consists of engine water tank, water pump, radiator, water pipe, etc. Cooling water from engine waterThe box flows to the radiator, and then dissipates heat through the radiator. At the outlet of the radiator, it is pumped back to the engine tank to form a cycle. In the process of water circulation, the radiator plays a very important role. It can transfer heat into the air and lower the temperature of the engine. Engine water pump The engine water pump is usually installed in the upper part of the engine and circulates through transmission devices such as belts or gears. The main function of the water pump is to suck the circulating water from the engine tank and press it into the radiator, achieve the cooling effect through the cooling of the radiator and then return it to the water tank. The performance of the water pump has a very important impact on the efficiency and stability of the cooling system. The engine radiator is usually located in front of the engine and is a very important part of the cooling system. It consists of many parallel heat sinks connected to a set of copper pipes.Hot water flows into the copper pipe and comes into contact with the plate. The heat will dissipate the air through the heat sink and fan. The heat dissipation capacity of the radiator directly affects the cooling effect of the engine. Maintenance of the engine water circulation system, as the core part of the cooling system, must be maintained frequently to ensure its effectiveness. The following are some of the most important aspects of maintenance and upkeep. 1. Regularly check the amount of water and concentration. Insufficient circulating water volume will affect the cooling effect. The amount and concentration in the water tank should be checked regularly to ensure sufficient circulating water volume and appropriate concentration. Two. Regular replacement of circulating water will cause scale and precipitation to block the circulation system due to impurities and corrosion. Regular replacement of circulating water can effectively remove debris in the cooling system and maintain the health of the circulation system. 3. Check the water pipes regularlyThe connecting water pipe is a transmission tool for the cooling system. Regularly check whether the water pipe is leaking. Aging, corrosion and other phenomena may also occur during long-term use. You should regularly check whether the water pipe is loose or damaged. In summary, the engine is one of the most important parts of the car, and the cooling system is the key part to ensure the normal operation of the engine. As a core component of the cooling system, the water circulation system will affect the performance and service life of the car if there is a problem. In order to ensure the safe and stable operation of the engine, every car owner should regularly check and maintain the cooling system. If you find any problems, you should replace the corresponding parts in time or seek help from professionals to avoid accidents.
