What causes severe shaking when starting in first gear with half-clutch without giving gas?
2 Answers
Severe shaking when starting the car in first gear with half-clutch may be caused by uneven wear of the clutch pressure plate, resulting in insufficient power. Other possible causes include incomplete fuel combustion, excessive engine carbon buildup, or insufficient engine power itself. Additional information is as follows: 1. Manual transmission shifting techniques: Become familiar with clutch pedal operation and develop good habits. Press the clutch pedal all the way down when engaging, and release it slowly. Always use first gear when starting, paying attention to the coordination between the throttle and clutch. Gradually release the clutch after the car starts moving. 2. Finding the right shifting timing: Generally, shift when the RPM reaches 2000, but remember to fully depress the clutch before changing gears. Gear selection should match the speed. Mismatched gears and speed can cause increased vehicle wear, higher fuel consumption, or in severe cases, stalling that may lead to accidents.
Hey, I've encountered this issue several times. When I first started learning to drive, I used to start in first gear without giving any throttle while in the semi-clutch state, and the car would shake like it was dancing, as if the whole vehicle was protesting. The reason is actually quite simple: the engine RPM was too low, around only 1000 RPM, which means insufficient power, and the clutch disc couldn't transmit enough torque when partially engaged. If you're used to operating without giving throttle, it might also accelerate clutch disc wear, leading to permanent slipping or abnormal noises. What's the solution? Later, I learned to lightly press the throttle to raise the RPM to around 1500, then slowly release the clutch to find the engagement point, which made the start much smoother. If the shaking persists even after repeated practice, it's best to have the clutch and ignition system checked at a repair shop to avoid damaging the car.
