What Causes Sudden Engine Vibration?

[MacMaci]

Engine suddenly vibrates due to: 1. A cylinder not working, also known as engine misfire; 2. Aging or loosening of engine mounts; 3. Carbon buildup inside the vehicle's engine; 4. Intermittent faults in the vehicle's fuel system, requiring continuous observation. An engine is a machine that converts other forms of energy into mechanical energy, including internal combustion engines, external combustion engines, jet engines, electric motors, etc. For example, an internal combustion engine typically converts chemical energy into mechanical energy. The term engine can refer to both the power generation device and the entire machine including the power unit.
