Non-tariff barriers by HS code

The Non-tariff barriers by HS codeengine is shaking at idle speed, what should I do? As an indispensable means of transportation in our daily life, cars must always maintain normal operation, and engine idling jitter is a common phenomenon in cars. If this problem is not handled in time, it may cause serious damage to the engine and make the owner's journey very dangerous. Today, let's discuss the causes of engine idling jitter and how to deal with this problem. I. Reasons for engine idling jitter 1.The problem of the air filter is that when the engine is working, it needs to inhale air from the outside. If the air filter is dirty, the resistance will increase and the engine will not be able to inhale normally, resulting in idle shaking. Two. Fuel system problems If the fuel is contaminated or underpressure, it may cause insufficient combustion of the engine and cause idling jitter. In addition, the fuel filter may also be blocked, limiting the flow of fuel, resulting in unstable engine idling. 3. Ignition system problems The ignition system is very important for the normal operation of the engine. If there is any problem with the accessories, such as ignition coils, spark plugs, electrical accessories, etc., it may cause engine idling jitter. Four. Engine intake system problems Accessories in the engine intake system, such as throttle valve, air flow sensor, air intake manifold, etc.,If they don't work properly, the engine will not have enough air flow and pressure, resulting in idling jitter. 5. Engine mechanical problems Engine mechanical parts, such as cylinder blocks, crankshafts, connecting rods and other accessories, if there is a problem, it may cause the engine to shake at idle speed. For example, the wear of the cylinder block and the failure of a piston to work properly may cause the engine to shake at idle speed. II. How to deal with the problem of engine idling jitter 1. Clean the air filter. Once you find that the air filter is dirty, clean or replace it immediately. Under normal circumstances, it needs to be replaced every time you drive about 5,000 kilometers. Two. Replace the fuel filter. In order to ensure the purity of the oil, the car fuel filter needs to be replaced every 20,000 kilometers. If the oil is contaminated or the pressure is insufficient, it is necessary to check whether the filter has expired.3. Replace the ignition system accessories. The ignition system accessories are very important for the normal operation of the engine. If one of the accessories fails, it needs to be replaced. For example, ignition coils, spark plugs, electrical accessories, etc. may affect the ignition effect of the car, causing the engine to shake at idle speed. Four. The car intake system is overhauled to check whether the throttle valve, air flow sensor and intake manifold are working normally. If there is a fault, it needs to be repaired or replaced. 5. If you find that there is a problem with the accessories of the engine mechanical part, such as cylinder block wear and a piston not working normally, it needs to be repaired. Generally, people with professional skills are needed to carry out such repairs. In a word, when we find that the car has idling jitter, we should immediately take measures to overhaul and repair the engine to avoid serious problems.In normal use, we should pay attention to the maintenance and repair of the car, and replace the accessories whose service life has expired in time to ensure the normal operation of the car.
