HS code-based tariff reconciliation

The HS code-based tariff reconciliationengine is a little shaking (the engine is shaking, does it need maintenance?) Vehicles are one of the indispensable means of transportation in modern life. Normal maintenance can not only extend the life of the vehicle, but also ensure driving safety. However, in daily use, engine shaking is one of the most common problems for drivers. There are many reasons for engine shaking, some of which are mild, while others need to be repaired immediately. Next, let's learn about the causes of engine shaking and how to deal with it. 1. To understand the cause of engine vibration, we need to know the working principle of the engine first. The engine will ignite the fuel mixture through the ignition system so that the car can run. EngineJitter is caused by multiple factors, such as failure of the ignition system, dirty or worn air filter, mechanical failure of the engine, etc. Two. How to judge whether the engine jitter needs to be repaired? When you find that the car has jitter, the premise of judging the problem is to make a simple diagnosis first: such as checking whether there are other abnormalities on the dashboard, such as burning oil, excessive water temperature, etc. If not, then the jitter problem is high-quality. . The next step is to judge by experience. If you drive the vehicle to the repair station, the staff may diagnose the following aspects: 2.1 Ignition system failure. Because the ignition system is the first step of engine operation, if there is a problem with the ignition system, it will directly affect the operation of the engine. When you start the car, sendThe motive makes a "bang, bang, bang" sound, which may be caused by a failure of the ignition line or ignition plug. 2.2 Cylinder problems. When you accelerate and find that the car's jitter becomes more serious, it is likely that there is a problem with one cylinder of the car or multiple cylinders are damaged at the same time. Cylinder problems may cause the car to lose power. At this time, you must go to the repair station for maintenance immediately. 2.3 The air filter is blocked. Because driving for a long time will cause dirty air from the air filter to enter the engine, it may cause the car engine to shake. In other words, it is very important to check and replace the air filter regularly. 2.4 Sensor failure. During the operation of the vehicle, sensor failure is easy to occur, which may cause engine shaking. Therefore, when you find that the car is shaking, you can check the sensor and software system to determine whether maintenance is needed.3. How to deal with engine jitter After understanding some common causes of engine jitter, the next step is to deal with the problem. 3.1 Replace the ignition line or ignition plug. If you find that it is a problem with the ignition system after a simple self-diagnosis or professional diagnosis, please replace the ignition line or ignition plug immediately. This will help eliminate unnecessary jitter and engine noise. 3.2 Regular replacement of the air filter. If the air filter is too dirty or blocked, it will lead to insufficient air flow, which will lead to engine shaking or extinguishing. Therefore, it is recommended to check the air filter and replace it when necessary. 3.3 Check and maintain the cylinder. If the cylinder fault of the car is found after diagnosis, you need to immediately send the car to the repair station for maintenance by professional technicians. The problem of the cylinder is likely to cause the vehicle to lose power and even threaten the life and safety of the driver, so it must be repaired in time.3.4 Replace the sensor or software. If the sensor or software fails in the vehicle, you need to replace or repair it with the help of professional technicians. With the continuous progress of automobile technology, electronic devices have been fully used in today's automobiles, so maintenance may be more complicated. If you can't handle it yourself, don't make the wrong decision in order to save money and seek professional help as soon as possible. In a word, engine shaking is a typical sign of a problem with the car. However, the correct handling and maintenance methods can keep you away from trouble and danger and bring a longer service life for your car. Maintaining good maintenance habits will help you diagnose and solve potential problems early, so as to ensure your driving safety.
