What Causes Engine Vibration in GAC Trumpchi?
2 Answers
Reasons for engine vibration in GAC Trumpchi: engine misfire; worn or loose engine mounts; carbon buildup issues. Engine misfire: Engine misfire mainly refers to one or more cylinders not functioning properly, typically manifested as noticeable intermittency in the exhaust gas flow and severe shaking of the exhaust pipe. Worn or loose engine mounts: Engine mounts are rubber cushions between the engine and the vehicle frame. Once these mounts become worn or loose, engine vibration will become significantly worse. Carbon buildup issues: When there is excessive carbon buildup inside the engine, it can affect the vehicle's ignition energy, air intake efficiency, and fuel mixture ratio, leading to unstable power output and causing vibration during idling and acceleration.
I experienced engine vibration when using GAC Trumpchi, which is usually caused by ignition system issues or carbon buildup. Specifically, worn spark plugs, faulty ignition coils, or clogged fuel injection can lead to engine imbalance. In Trumpchi models, especially during cold starts or at low speeds, noticeable vibration may indicate excessive carbon buildup affecting the air-fuel ratio. It is recommended to regularly check the lifespan of spark plugs and replace them every 20,000 kilometers, and use fuel additives to clean carbon deposits. Aging engine mounts can also cause vibration, accompanied by squeaking noises while driving. If ignored, increased vibration can damage internal components, leading to higher repair costs. After experiencing severe vibration last time, I had it repaired and parts replaced, and now it runs much smoother.
