China HS code interpretation guide

Engine cleaning (improve your car performance: precision engine cleaning) Car engines are China HS code interpretation guideone of the cores of the whole car system.If the car engine does not perform well, the whole car system is likely to have problems, causing a lot of trouble for the driver. Over time and the gradual increase of mileage, the car engine will produce some dirt and carbon deposits, which will affect the function and performance of the engine. However, by using sophisticated engine cleaning technology, these dirt and carbon deposits can be effectively removed, the performance of the engine can be improved, and the service life of the car can be extended. What is engine cleaning? Engine cleaning refers to the process of using special chemical cleaning agents and technologies to thoroughly remove oil and carbon deposits in the engine, so as to improve its performance and efficiency. Engine cleaning can be done in different ways, such as entering the combustion chamber through the spray system, or cleaning through the oil filter and oil system.However, before the engine is cleaned, a comprehensive vehicle inspection must be carried out to ensure that no other problems will affect the cleaning effect. Why do we need to clean the engine? There are many parts inside the car engine, and the adhesion of oil and carbon deposits between them will affect the performance and function of the engine. These oil stains and carbon deposits may cause the spark plugs of the engine to not work properly or block the oil line, increasing the fuel consumption of the car and reducing the power. In addition, engine cleaning can also improve the power output and reliability of the engine, extend the service life of the engine, and reduce the cost of car maintenance. Under what circumstances does the engine need to be cleaned? Under normal circumstances, a car needs to be cleaned once every 10,000 kilometers of driving. However, the engine may need to be cleaned in advance in the following cases. -The car has problems such as fire, insufficient power, increased fuel consumption, etc. - the engine noise becomes louder - there is jitter at the start, and there is obvious vibration when accelerating - the engine idle speed is unstable, and the engine is often turned off. The advantages of cleaning the engine - Improve the performance and efficiency of the engine - Reduce the fuel consumption of the car - Extend the use of the engine Life - Reduce the cost of car maintenance. Disadvantages of engine cleaning - Relatively high cost - Some cleaning agents will produce a certain degree of corrosion during use, which may cause damage to engine parts - Engine cleaning requires experienced professionals to operate. If the technology is not skilled enough, it is likely to The implementation process of engine cleaning will cause more serious problems. The implementation process of engine cleaning is generally as follows: 1. Car inspection: Send the car to the car repair shop for a comprehensive inspection to ensure that the engine can be cleaned.Two. Engine cooling: After the engine cools down, open the radiator cover, open the water plug clockwise, and clean the water in the water tank. Basically, it is appropriate to pour it once or twice. 3. Add cleaning solution: After draining the water, pour a special cleaning solution into the car coolant, and then pour an appropriate amount of water. After adding the liquid, start the car and start the engine so that the liquid can circulate fully. Four. Sewage discharge liquid: The circulating cleaning liquid will bring out the dirt and carbon deposits accumulated in the engine, so as to achieve the cleaning effect. Wrap the opening with a cotton cloth and put it down, and collect the liquid and dirt in the basin below. 5. Wash: Use a high-pressure water gun to wash the coolant outlet to ensure that the cleaning solution is thoroughly rinsed. 6. Add coolant: Under the condition that the cleaning liquid has been thoroughly rinsed, add the car coolant again to ensure that it reaches the correct water level.The cost of engine cleaning The cost of engine cleaning may vary by region and car type. Generally speaking, the cost of complete engine cleaning service is about 1,000-2,000 yuan. It should be reminded here that if the selected service provider is not good, there may be problems during the cleaning process, resulting in greater losses. Therefore, you must choose a reliable engine cleaning service provider. Things to pay attention to in engine cleaning - The whole process of engine cleaning needs to be monitored to ensure the safety of the whole process. - Do not turn off the engine during the cleaning process, otherwise it may cause contact between the engine cylinder head and the cylinder wall, resulting in serious damage. - When cleaning the engine, Use the detergent strictly according to the instructions and follow the advice of the car maintenance engineer.Conclusion Engine cleaning is a necessary car maintenance activity. If the engine is cleaned irregularly, the performance and reliability of the car will be affected. However, before cleaning the engine, you must find a reliable engine cleaning service provider to avoid damage to the car caused by improper operation. Therefore, choosing the right service provider and technical solution can reduce maintenance costs and extend the life of the car while ensuring the performance of the car.
