Why does the new car have obvious jerking sensation?
1 Answers
Car jerking sensation is related to two major components: the engine and the clutch. There are many factors that may cause jerking during car startup and low-speed acceleration, such as engine oil passage blockage, insufficient or deteriorated transmission oil, unskilled operation of clutch and throttle coordination, or releasing the clutch too quickly during startup. The following are relevant introductions about jerking sensation: 1. Related to the engine: If the car has a jerking sensation while driving, the engine is definitely involved. The engine's ignition, air intake, and fuel injectors collectively determine fuel combustion, which is also the power source of the engine. If the air intake volume decreases, ignition weakens, or the fuel injection reduces, the power will be insufficient, resulting in a jerking sensation. 2. Normal situation: Jerking during the startup of an automatic transmission car is normal, because except for CVT continuously variable transmission, other transmissions will have a jerking sensation.
