Why does the car jerk when releasing the clutch?
1 Answers
Car jerking when releasing the clutch is caused by a mismatch between the engine speed and the current vehicle speed, meaning there is a speed difference between the engine speed and the clutch disc speed. Reasons for jerking when releasing the clutch: Lifting the throttle too early, i.e., releasing the throttle before pressing the clutch during gear shifting, can cause a jerking sensation. Lifting the throttle too late, i.e., pressing the clutch without timely throttle release during gear shifting, can cause the car to accelerate momentarily during the semi-clutch phase, and a power disconnection after full separation can lead to jerking. Methods to prevent jerking: In most cases, the engine speed is lower than the clutch disc speed. After shifting into a new gear, when lifting the clutch to the semi-engaged position, ensuring the engine speed matches or slightly exceeds the clutch disc speed can effectively prevent jerking. Proper coordination between the throttle and clutch is crucial. The speed of releasing the clutch depends on the gear and speed, and the throttle should be adjusted accordingly. Slowly releasing the clutch while applying a bit of throttle can reduce jerking.
