Why Does the Engine Shake While Driving?

[IsabelDella]

Reasons for engine shaking while driving: 1. The engine mount's function is to reduce vibration and provide cushioning during engine operation, as well as to secure the engine. Once the engine mount becomes aged or loose, engine shaking becomes noticeably abnormal. 2. Excessive carbon buildup inside the engine reduces the car's ignition energy and intake efficiency, ultimately leading to symptoms such as engine shaking and sluggish acceleration. 3. Using incompatible fuel octane ratings can result in decreased car output power and reduced performance. Alternatively, if the fuel tank cap vent is blocked, or if the fuel tank switch, fuel filter, or the fuel line between the fuel tank and carburetor are partially obstructed, the required fuel supply cannot be met, leading to an overly lean air-fuel mixture and engine shaking. 4. If the air filter is not cleaned in time after prolonged use and becomes clogged, insufficient air intake will cause an overly rich combustible mixture, reducing engine power. For vehicles equipped with a turbocharger, any malfunction in the turbocharging device can also cause the engine to shake during acceleration.
