What Causes Engine Shaking and Abnormal Noises?

[MacLucia]

The engine is a crucial component of many machines. The reasons for its shaking and abnormal noises are as follows: 1. Root Cause: Engine mount damage. The mount endures continuous repeated impacts, making the rubber prone to fatigue. The high heat generated over time will inevitably cause the vibration-damping rubber to age, reducing its damping effect. Replacement is necessary to prevent the impact vibrations generated during engine operation from being transmitted into the vehicle. 2. Damage to the soft connection rubber between the engine and the frame. The natural lifespan of rubber is 5 years, while the design lifespan of the engine mount rubber is 80,000 to 100,000 kilometers. Therefore, whether it's pure rubber or hydraulic mounts, issues like rubber aging or damage exist, requiring inspection and replacement. 3. Other Causes: Factors such as flywheel issues, cylinder misfires, and carbon buildup can also lead to idle shaking.
