HS code-based tariff reconciliation

The HS code-based tariff reconciliationengine sound is abnormal (the engine is abnormally noisy, the owner should deal with it in time) The engine of the vehicle is the core of the whole vehicle. In the process of driving, if there is an abnormal engine sound, it is likely to be There is a problem within the motivation. For many car owners, when the vehicle has an abnormal engine sound, they do not immediately realize that this is a serious problem, and are likely to ignore this problem, thinking that it is just a momentary problem. However, this idea is wrong, because the abnormal engine sound is a relatively serious problem. Once this happens, the owner should deal with it in time, otherwise it will lead to more serious consequences. So, what is the abnormal sound of the engine? OneGenerally speaking, under normal circumstances, the engine operation sound of the vehicle is very smooth, and the engine will make a regular, low and stable sound during operation, which is very comfortable. However, if the engine makes a noisy and trembling sound, or if there is a relatively loud noise after the engine is turned on, then these situations fall into the category of abnormal engine sound. There are many reasons for the abnormal sound of the engine, such as abnormality of the oil road system or braking system, insufficient or oil pollution of the engine, serious wear of engine parts, etc. These problems may lead to abnormal sound of the engine. There are many reasons for the abnormal sound of the engine, and the car owner should deal with it in time. First of all, loud engine noise is a common abnormal situation. This situation is usually caused by excessive wear of engine parts.Some parts of the engine, such as connecting rods, crankshafts, rocker arms, crankshaft bearings, etc., will wear out if used for a long time, resulting in a decline in the performance of the whole engine and loud noise at the same time. If this happens, the owner should check in time whether the engine parts are excessively worn and need to replace new parts. Secondly, the engine burned oil. This situation is usually caused by insufficient engine oil or oil contamination. If the engine oil is insufficient, the internal parts of the engine will rub to generate heat, which will burn the oil, resulting in an increase in the internal temperature of the engine and abnormal noise. If the engine oil is contaminated, the oil will lose its lubrication effect, resulting in increased friction between engine parts, thus causing abnormal noise. If this situation is found, the owner should add or replace the oil in time to ensure the normal operation of the engine.Finally, if the noise generated by the vehicle is equipped with too large or too small spark plugs for a long time and driving in an ultra-high temperature environment for a long time, it will also reduce the performance of the engine and produce various abnormal noises. At this time, the owner should pay attention not to let the vehicle drive in such a special environment for a long time. In a word, abnormal engine sound is a relatively serious problem. Under normal circumstances, the engine operation sound of the vehicle should be stable, low and stable. If abnormal sound of the engine is found, the owner should deal with it in time, understand the cause of the engine problem, and take effective measures to Repair. If you don't pay attention to maintenance, the operation of the engine will cause more serious consequences. Therefore, car owners should do a good job of every maintenance and inspection to ensure that the vehicle is running in the best condition.
