HS code-based scenario planning for exports

Overheating of the car engine is HS code-based scenario planning for exportsa problem that many people often encounter, which may be caused by some reasons.Especially in hot weather, if the water temperature gauge of the vehicle is not paid enough attention, the temperature of the vehicle will continue to rise while driving, which will cause great damage to the engine. So, how to avoid engine overheating? What should I do when the engine overheats? I. There may be many reasons for engine overheating, but most of the reasons can be summarized as follows: 1. The lack of cooling water in the circulation system Cooling water is very important for the engine. It can bring the high-temperature substance burned inside the engine into the radiator to dissipate heat and reduce the temperature of the engine. If there is not enough water in the cooling system, it will lead to poor heat dissipation, which will cause the engine to overheat. Two. The water pipe or radiator is blocked. When the water pipe or radiator in the cooling system is blocked, the heat cannot be dissipated, resulting in overheating of the engine.Therefore, it is very necessary to regularly check and clean the cooling water system and radiator of the engine. 3. It is normal for the engine oil of water-containing vehicles to contain a small amount of moisture. However, if it is found that the engine oil has turned milky white, or the water temperature gauge continues to rise, it may be because the water in the engine has flowed into the oil pump. At this time, it is necessary to check whether the engine oil contains moisture. Four. The fault of the engine accessory drive wheel is that the accessories connected to the engine include generators, air conditioning compressors, pumps, etc. If the drive wheels of these accessories are damaged, it will cause the engine to overheat. 5. The hot summer is one of the seasons when the car engine overheats. This is because the hot summer climate will increase the load of the engine, resulting in a rapid rise in the engine temperature.II. Issues to pay attention to 1. If the water temperature gauge rises, please stop immediately. Once you find a rise in the water temperature gauge, you should immediately find a place to stop the car. Remember not to let the engine continue to run, otherwise it will cause damage to the inside of the engine, and you need to wait for it to cool down before starting again. Two. Don't open the coolant lid immediately. Once you find that the engine is overheated, the most important thing is not to open the coolant lid immediately, because it will cause gasoline or coolant to be sprayed out, thus damaging the engine. 3. Use the radiator to spray water. If you can't find a suitable parking lot immediately, you can drive the car to the side of the road (do not stop on the highway), stop and let the radiator "gasp" as much as possible, and then you can spray hot water or warm water on the radiator to cool down. But remember not to let the cooling water spray on the hot parts of the engine.Four. The coolant should be checked. Once you find that the engine is overheated, you should check whether the coolant is insufficient and add water in time. If it is determined that the coolant is insufficient, you can use a water filler to add water to the car on the roadside. III. How to prevent the engine from overheating? 1. Regular detection of coolant Regular inspection of coolant in the vehicle is the key to preventing the engine from overheating. Regular testing can check whether the level and color of the coolant are suitable. If the level is low, water should be added. If the color is turbid or pale, the coolant needs to be replaced. Two. I often check the fan system of the engine. My model (Mercedes-Benz) comes with an electric fan system, which can control the temperature of the engine very well. Therefore, it is crucial to check the condition of the fan and fan belt frequently. 3. Regularly check the cooler of the car. The cooler is one of the important accessories in the car engine in addition to the coolant.Therefore, it is also very important to regularly check the state of the cooler and whether there is foreign matter attached. Four. Regular inspection of engine oil and regular inspection of the level and quality of engine oil is also one of the important ways to prevent engine overheating. If the engine oil is emulsified, you should check whether there is a problem inside the engine. In a word, we should avoid overheating of the engine. The maintenance and upkeep of the car must be done on the basis of ensuring driving safety. Abide by the maintenance and maintenance cycle, frequently check the indicators of the vehicle, find vehicle problems in time and repair them in time, which are all important safeguard measures to ensure the long-term normal operation of automobile engines.
