What Are the Causes of Engine Shaking Faults?

[AaronLee]

Here are the causes of engine shaking faults: 1. Shaking caused by engine mechanical components: The engine continuously wears during operation, and the gap between the cylinder wall and the piston will also become larger. However, the degree of wear in each cylinder may not be the same. During cold starts, the lubrication effect of the engine oil is relatively poor, and the gap between the cylinder and the piston may leak some high-temperature gas, leading to unstable cylinder operation and a certain reduction in power output. The cost of detection and repair is also relatively high. 2. Abnormal water temperature sensor: The operating condition of the engine is usually judged by the water temperature sensor. If the sensor transmits incorrect information (usually manifested as a significant difference between the transmitted temperature and the actual external temperature), it can cause abnormal fuel injection by the engine's fuel injector, making shaking problems inevitable.
