What is the jitter of 202 1 Yinglang four-cylinder engine?

The reason why Buick Hideo engine of Pacific Auto Network shakes badly is 1. The throttle valve is too dirty or damaged, causing idling vibration. You can clean the throttle first. If the fault still exists, you need to replace the throttle. 2. The spark plug does not work, resulting in cylinder loss and idle jitter. Check the spark plug and ignition module for faults.

1. Engine cylinder shortage mainly refers to the abnormal operation of the cylinder in the engine, which is usually manifested as: the exhaust gas flow discharged by the vehicle is obviously intermittent, and the exhaust pipe vibrates seriously, so the engine _ body _ jitter can be obviously felt, which is caused by _ half _ ignition coil or spark plug.

2. The so-called machine foot glue is a rubber block between the engine and the frame, which is used to reduce the vibration of the engine when working and fix the engine. Once the foot glue is aged or loosened, the body _ engine will change abnormally. As long as the foot glue is changed again, the effect will be immediate.

3. Carbon deposition. At present, there is no engine with combustion efficiency of 100%, so the problem of carbon deposition is inevitable. Carbon deposition includes cylinder carbon deposition, throttle carbon deposition, spark plug carbon deposition, intake carbon deposition and so on. When the carbon deposit in the engine exceeds _, it will affect the parameters of _ series _, and even lead to the instability of the power output of the automobile, and the jitter will occur when idling and accelerating. Solution.

4. If the fuel system fails, adding the number _ _ adaptive _ fuel (for example, adding the number 95 to the number 92) will lead to serious engine jitter, because the more fuel numbers, the worse the antiknock performance; Or because the vent hole of the fuel tank cover is blocked, the fuel tank switch, fuel filter and the oil pipe between the fuel tank and carburetor are partially blocked, which can not meet the required oil quantity and supply, resulting in too thin mixture and engine jitter. It is recommended to go to a regular gas station to refuel and use the fuel label specified by the manufacturer. Take _ _ common _ causes of engine jitter as an example. In fact, engine jitter is not terrible, because this situation often leads to _ aging of accessories or _ improper use. As long as you check it in time, you will be completely relieved.
