Pre-export HS code verification steps

Engine air leakage (car owner's attention! Engine air leakage may become a fatal injury,Pre-export HS code verification steps which needs to be dealt with as soon as possible!) As an important means of transportation for us to travel, the engine of the vehicle is the core part of the vehicle. The engine itself withstands harsh working conditions such as high temperature and high pressure and high speed operation. If the engine leaks air, it will seriously affect the performance and safety of the vehicle. Therefore, when the owner finds the problem of engine leakage in the vehicle, he must deal with it in time to avoid the failure or accident of the vehicle. I. Causes of engine air leakage 1. Missely sealed: The top cover, rocker box, cylinder head, etc. of the engine components are not tightly sealed, which will lead to gas leakage.Two. Deformation and wear: The parts of the engine will have certain deformation and wear after long-term operation. For example, crankcase distortion, cylinder liner wear, piston wear, etc., all of which may cause air leakage. 3. Damaged gas tank and water tank: The gas leak may also be caused by damage to the gas tank and water tank parts. The main reason for engine gas leakage is the dispersion of pressure, or the aging and cracking of the seal. Four. VALVE PROBLEM: THE JOINT PART OF THE VALVE IS AN IMPORTANT SEALING SYSTEM. IF THE VALVE FAILS, IT WILL ALSO CAUSE ENGINE AIR LEAKAGE. II. Judge whether the vehicle is leaking 1. Check the engine cover: When the engine is running, first check whether the engine cover is leaking. Once the leak is found, the engine cover seal should be repaired or replaced immediately. Two. Check the exhaust pipe: When an abnormal sound is heard, it also means that there is an air leakage problem in the car.The car runs stably when there is no air leak, but sometimes when the car starts to run, you can hear an obvious close-up explosion or it makes a harsh noise. 3. Check the fuel injector: The oil leakage problem of the car usually shows that it leaves oil marks on the road and is damaged at the bottom of the car. The problem of air leakage can be determined by checking the fuel injector. III. Countermeasures The seriousness of the engine air leakage problem should not be negrated. If it is not dealt with in time, it may cause serious accidents, so it should be solved in time. 1. Overhaul seals: For air leakage, you should first find the location of the air leakage to determine which parts cause the gas leakage. Common air leakage parts include valves, valve ducts, cylinder heads, piston rings, etc. After inspection, it is found that the parts to be processed are all related to seals, so the air leakage problem can be repaired by replacement or renovation.Two. Replace damaged parts: such as piston oil ring blockage, aging of the sealing ring, damage to the valve sheet, etc. These damaged parts need to be replaced in time. 3. Improve the quality of oil: The quality of automobile oil directly affects the life of the engine, ensuring that the quality of the oil in the oil pool is stable, and the use of oil that can improve the lubricity of the locomotive engine is also an important measure to alleviate engine gas leakage. Four. Replace the engine if necessary: For serious air leakage problems, such as damage to the engine body or other damage, it is wise to replace the engine equipment. It can ensure driving safety. In a word, once the engine air leakage problem occurs, the car owner needs to actively take countermeasures. Eliminate the potential danger of air leakage as soon as possible to prevent accidents. At the same time, during normal vehicle use, the engine should be inspected regularly.Check and maintain, change engine oil and other lubricating materials in time, continuously ensure the normal operation of the engine, and ensure the safety and comfort of your travel.
