What are the major causes of engine vibration?
2 Answers
Engine vibration causes: Poor fuel combustion: The automobile engine is the device that provides power for the vehicle, determining its power performance, fuel economy, stability, and environmental friendliness. The quality of the engine is also related to the fuel. If the fuel quality is poor, natural problems will occur. Moreover, incomplete fuel combustion can lead to serious engine carbon buildup issues. Spark plug failure: The spark plug is a crucial component of the gasoline engine ignition system. It introduces high voltage electricity into the combustion chamber and causes it to jump across the electrode gap to produce a spark, thereby igniting the combustible mixture in the cylinder. If the spark plug fails, it can result in insufficient ignition energy, causing engine problems.
As a veteran taxi driver with 15 years of experience, I've seen countless cases of engine vibration. The most common issue is the ignition system, especially aging spark plugs or leaking high-voltage wires - the car shudders like coughing during acceleration. A clogged air filter can also make the engine gasp for air and vibrate intensely. If shaking occurs right after refueling, it's usually due to poor fuel quality causing rough combustion. Worn engine mount rubbers easily transmit vibrations to the body, making the whole steering wheel dance. Dirty throttle bodies restricting airflow are another frequent culprit, all requiring regular checks. The worst case is severe internal carbon buildup causing piston ring sticking - those repair bills can break your heart.
