How to choose correct HS code in ASEAN

Atz engine jitter: cause and How to choose correct HS code in ASEANsolution Atz is a luxury medium-sized car under Mazda. Its power system is equipped with Mazda's high-efficiency fuel engine Atz engine. However, some car owners will encounter Atez engine jitter problems during use, which is very common. Today, let's analyze the causes and solutions of ATZ engine jitter. I. The reason for the shaking of the ATZ engine 1. Improper vehicle maintenance of the Atz engine needs to be strictly inspected and maintained before use. If the owner does not replace the oil and filter according to the recommended cycle during use, or does not maintain and clean the engine in time, it will cause a large amount of impurities and dust to accumulate inside the ATZ engine, resulting in engine shaking.Two. Ignition system failure If the ignition system of the ATZ engine fails, such as the failure of the ignition coil or the failure of the ignition plug, it will cause pain and shaking of the engine. This is because the problem of the ignition system will disrupt the smooth operation of the engine system, thus causing engine shaking, and may even affect the safety of vehicle driving. 3. The problem of air-fuel ratio The ATZ engine needs to maintain the correct air-fuel ratio when running. If the air-fuel ratio is too high or too low, it will cause the engine to burn incompletely and the engine to shake. This is usually caused by the failure of the air flowmeter or oxygen sensor, and the air-fuel ratio needs to be reset after repair. Four. Transmission system problems The jitter of the ATZ engine may also be caused by the failure of the transmission system. If there is a problem with the clutch or transmission, it will affect the smooth operation of the engine, resulting in shaking and pain.II. The solution to the jitter of ATZ engine 1. Replace the oil and filter to check whether the oil and filter of the vehicle are replaced according to the specified time and mileage. When replacing, you should try to choose the original accessories to ensure the normal operation of the engine. If you find that the oil is black and has a strange smell, it means that there is too much silt and dirt attached to the oil, and it needs to be replaced in time. Two. Check the ignition system. If the ignition system fails, it is necessary to check whether the ignition coil and ignition plug of the vehicle are damaged. If there is a problem, it needs to be repaired and replaced. 3. Clean up the air intake system. Dust, oil smoke and other impurities will accumulate in the air intake system of the Atz engine, which need to be cleaned regularly. In addition, the air flowmeter and oxygen sensor in the air intake system also need to be checked and maintained to avoid problems with the air-fuel ratio. Four. Check the transmission system. The vibration of the Atz engine may also be caused by problems with the transmission system.It is necessary to check whether the clutch and gearbox are working properly. If there is a problem, it needs to be repaired and maintained. Summary: Atz engine jitter is a very common problem. It is necessary to follow the regular maintenance and inspection procedures. If there is a problem, it should be eliminated in time, and impurity filters, spark plugs and other components should be replaced in time. Maintaining the stability of vehicle quality can extend the life of the vehicle and improve the stability and driving safety of the vehicle.
