WTO harmonization and HS codes

Engine crankshaft oil seal (the failure of the automobile crankshaft oil seal affects the engine) The WTO harmonization and HS codesautomobile crankshaft oil seal is one of the key engine parts. Its main function is to prevent oil leakage and maintain normal oil pressure. If the crankshaft oil seal fails, it will affect the performance and life of the engine. First of all, the failure of the crankshaft oil seal will cause oil leakage. Oil is an important lubricant for lubricating engine parts. If the oil leaks, it will cause the engine to lack oil and increase friction, which will cause excessive wear and even burning of parts and other problems. Under normal circumstances, the engine crankshaft oil seal will naturally age after a certain period of use, and then in the process of high-speed driving or acceleration, due to the acceleration of the crankshaft rotation speed, high temperature and high pressure are generated on the surface where the crankshaft and the oil seal are closely matched, resulting in oil seal cracking and oil leakage. Secondly, the failure of the crankshaft oil seal will also affect the oil pressure of the engine and directly affect the operation of mechanical parts.Under normal circumstances, the oil flows to each part through the oil pump, maintaining the lubricating film on the surface of the parts, reducing the friction between the metal surfaces, and playing an important protective role in the operation of the engine parts. If the crankshaft oil seal fails, it will lead to increased oil loss, decreased oil pressure, engine tremor and increased noise, which will eventually lead to excessive wear of parts and engine damage. Finally, the failure of the crankshaft oil seal will also affect the fuel consumption of the engine. In the case of crankshaft oil seal failure, the continuous leakage of oil causes the engine to run out of oil, and the lack of oil in the engine will lead to abnormal wear and tear of the engine. Therefore, this will affect the fuel consumption of the car. It should be noted that the failure of the crankshaft oil seal will also lead to some other problems, such as reduced engine coolant and difficulty in starting the engine. In summary, the crankshaft oil seal fails.The impact on the engine is huge and must be dealt with in time to avoid problems such as oil leakage, oil pressure drop, excessive wear and increased fuel consumption. Car owners can prevent and repair in the following ways: 1. Replace the crankshaft oil seal regularly: It is recommended that the owner replace the crankshaft oil seal every 30,000 kilometers or a year to ensure normal oil tightness and reduce the chance of failure. Two. Inspection and maintenance: Pay attention to regularly check the capacity and quality of oil and coolant, find and repair problems in time, and keep the engine clean. 3. Seek technical support: If you find oil leakage or other problems, you should inspect the car in time and consult professional and technical personnel in order to find and solve the problem in time. In a word, for automobile crankshaft oil seals, timely prevention and maintenance is the best way to avoid failures and maintain the engine.The owner should regularly check and replace the crankshaft oil seal while keeping it clean, so as to reduce the occurrence of oil leakage, oil pressure drop, excessive wear and increased fuel consumption, maintain the engine in good working condition and extend the life of the engine and the car during long-term use.
