How to choose correct HS code in ASEAN

neutral engine jitter (solution to engine jitter problem) The How to choose correct HS code in ASEANengine is the core component of the car, and its performance determines the performance and service life of the car.However, in the daily use of the car, we sometimes encounter the problem of engine shaking. Especially in the case of idle gear, the jitter problem will be more obvious. So, what is the cause of the jitter of the idle engine and how to solve this problem? I. The reason for the shaking of the idle engine 1. The air flow sensor fails. The air flow sensor is an important component of the microprocessor to control the air intake of the engine. If the sensor fails, it will lead to insufficient air entry in the engine and failure to achieve a reasonable air-fuel ratio, which will affect the normal operation of the engine and cause idle gear jitter. Two. Failure of the fuel supply system Failure of the fuel supply system is also one of the reasons for the shaking of the idle engine. The fuel supply system is the key to ensuring that fuel can be injected into the engine at the right time, pressure and temperature, so as to keep the engine running normally.If there are problems inside the system, such as insufficient fuel flow and blockage of the fuel injector, it may lead to the idle jitter of the engine. 3. Ignition system failure Ignition system is an important part of the normal operation of the engine, including natural gas filter, ignition coil, spark plug and other components. If any of these parts fails, there will be jitter during engine operation. When the engine is in idle gear, the speed is higher, and the jitter phenomenon will be more obvious. Four. Vacuum system failure The vacuum system monitors and adjusts all parts of the engine through a variety of sensors and wires, so as to maintain the stable operation of the engine. If any part of the vacuum system fails, such as the throttle valve, intake manifold, air pipe and other components, it will cause the idling jitter of the engine.5. Engine mechanical failure The mechanical structure of the engine is very complex and consists of multiple components. If there is any failure between these parts, it can affect the output power and the operating status of the engine, resulting in neutral gear jitter. II. How to solve the jitter of the idle engine 1. Check whether the air flow sensor is normal when there is idle jitter. You need to remove and clean the sensor, or replace the new sensor directly. If there is still jitter, the next check should be carried out. Two. Checking the fuel supply system is an indispensable part to ensure the normal operation of the engine. If there is a fuel supply failure, the fuel system needs to be checked and repaired. Such as replacing a new fuel injector, cleaning or replacing the oil pump, replacing the fuel filter, etc.3. Check the ignition system. The ignition system is the key to ensuring the normal operation of the engine. It is necessary to check for wear or process flashing problems, replace the new ignition coil or spark plug, and reformulate the ignition time. Four. Checking the vacuum system is an important part of the engine regulation performance. If there is a problem, you need to check whether the vacuum tube is damaged, whether the throttle valve is smooth or tightly sealed. 5. Check the mechanical fault of the engine. If the above does not work to solve the jitter problem, it is necessary to check whether the mechanical structure of the engine is faulty, such as whether each piston moves smoothly and whether the connecting rod is loose. In a word, the jitter problem of the engine needs to be solved by checking and handling different parts of the engine. If you are not familiar with car technology, in order to ensure safety, it is recommended to send the vehicle to a professional car repair station for handling.
