Where do you usually need to check if the engine jitter is serious?

Severe engine jitter is caused by the following reasons:

1, the engine foot glue is aging or loose, which is the glue block between the engine and the frame. Its function is to reduce the vibration and buffer when the engine works and fix the engine. Once these feet are aged or loose, the engine jitter will be extremely obvious;

2. The engine lacks cylinders, mainly because one or more cylinders of the engine are not working normally. Generally, the exhaust gas flow from automobiles is obviously intermittent, and the exhaust pipe vibrates badly, and the engine can be obviously felt shaking, sometimes accompanied by sudden noise. This is mostly related to the failure of ignition coil;

3. Engine carbon deposit. The carbon deposit here includes cylinder carbon deposit, throttle carbon deposit, spark plug carbon deposit, intake carbon deposit and so on. These positions are closely related to the power output of the engine. When there is too much carbon in the engine, the ignition energy of the automobile decreases and the intake efficiency decreases, which eventually leads to the symptoms of engine jitter and weak acceleration.

solution

The best way is to clean the oil circuit, clean it regularly and use fuel additives such as PNF stock solution to solve the above problems caused by carbon deposition. The poor quality of fuel or the long storage time of fuel in the initial stage of a new car will lead to the rapid increase of colloidal components in the oil circuit, which will continuously pollute the fresh fuel, resulting in no good fuel to participate in the combustion in the later stage, and the carbon deposition exceeds the standard, especially for the national six cars.
