What is the RPM during clutch semi-engagement?
1 Answers
During semi-engagement, the RPM is equivalent to idle speed, typically ranging from 800 to 1000 RPM. If the accelerator is not pressed, this RPM will increase when the accelerator is applied. Clutch semi-engagement refers to the unstable connection state of the clutch, where the driver gradually reduces the pressure on the clutch pedal, causing the driving plate and driven plate to slip while rotating. Manual transmission vehicles often require semi-engagement for various operations, but prolonged use can lead to clutch wear. During driving tests, semi-engagement is used in the field test but is prohibited in the road test. The shorter the duration of semi-engagement, the better. Prolonged semi-engagement accelerates clutch disc wear. If frequent semi-engagement is necessary, ensure proper cooling by alternating between semi-engagement and disengagement. Avoid resting your left foot on the clutch pedal, as this keeps the clutch in semi-engagement and increases wear. Regular clutch maintenance is essential. If you notice a burning smell or difficulty shifting gears, the clutch disc may be damaged and requires immediate repair. When lifting the clutch pedal to the semi-engagement point, pause for 2-3 seconds before fully releasing it to prevent jerking or lurching.
