The causes of vehicle jitter during acceleration are: engine running problem, ignition system failure, nozzle failure and universal joint failure. Because when the car is driving, it is necessary to ensure that the engine has a good working condition. Generally speaking, the engine does not inhale enough gas, and the fuel is in poor contact with the outside air, which leads to the poor working condition of the engine, so the engine will shake when running.

First of all, from the cold start, the main reason for the body shake during cold start is insufficient fuel combustion, which leads to insufficient power of the car. The ignition energy is low, and more oil is needed to meet the power when starting, especially when the temperature of fuel and lubricating oil is low.

After a long time, the gap between the two poles of the spark plug gradually becomes larger, which leads to the reduction of ignition energy and poor fuel atomization, resulting in body jitter. In addition, the aging of ignition coil, aging of spark plug high voltage line or leakage will also lead to the decrease of ignition energy.

Aging or loosening of machine foot glue:

The so-called engine foot glue is the 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 engine foot glue is aging or loose, the body and engine will become abnormal jitter. We only need to change the engine foot glue again, and the effect is immediate.

Although there are many kinds of vehicles, their structures are similar. This should be said to be the credit of standardization and the need of large-scale production line. With the development of society, the progress of science and technology and the change of demand, the appearance of railway vehicles has also begun to change, especially the passenger cars are no longer the same old faces. However, their basic structure has not changed obviously, but the specific parts have more scientific and advanced structural design.
