What Causes Engine Vibration in Small Cars?
1 Answers
The causes of engine vibration in small cars are: 1. Excessive carbon buildup in the throttle body or intake manifold, or a clogged air filter element; 2. Poor performance of the ignition system, with suboptimal spark plug firing; 3. Abnormal fuel pump pressure, incorrect readings from the intake pressure sensor, or poor sensor performance; 4. Leaks in the intake manifold or EGR valve; 5. Malfunction of the mass airflow sensor or intake pressure sensor. The car engine is the power-generating device of a vehicle, serving as its heart, and determines the vehicle's power performance, fuel efficiency, stability, and environmental friendliness. Depending on the power source, automotive engines can be categorized into diesel engines, gasoline engines, electric vehicle motors, and hybrid systems, among others.
