What Happens When You Press the Accelerator While Depressing the Clutch?
2 Answers
Pressing the accelerator while depressing the clutch can cause wear on the release bearing. If you press the accelerator in this situation, the engine speed will increase, and the release bearing will also rotate rapidly, accelerating its wear. Under normal conditions, the release bearing only works briefly during gear shifts, allowing it to last for several years. However, if you rev the engine while depressing the clutch, it will significantly reduce the lifespan of the release bearing. Notes on coordinating the clutch and accelerator: 1. Proper coordination between the clutch and accelerator ensures smooth power transmission from the engine, facilitating a stable start for the vehicle, saving fuel, and extending the clutch's service life. Poor coordination often results in stalling or body shaking during startup. 2. As the vehicle speed increases, the process of coordinating the clutch and accelerator during gear shifts should be shortened, and the speed of releasing the clutch pedal should be increased. However, avoid lifting the clutch pedal completely in one motion; instead, include a brief slow and pause phase to ensure smooth power transmission. To guarantee seamless gear shifting, the throttle pedal should also be pressed lightly and reasonably coordinated, avoiding sudden or harsh presses.
I remember when I was first learning to drive, I used to make this mistake all the time. In a panic, I'd press both the clutch and the accelerator simultaneously, causing the engine to roar deafeningly while the car remained motionless like a log. My instructor would glare at me in frustration, saying it was purely a waste of fuel and a noise nuisance. Back then, I didn't understand the principle, but later I got it: pressing the clutch disconnects the engine from the wheels, so stepping on the accelerator is futile—it only revs the engine into the red zone, wasting money and damaging the engine. Over time, I also realized that prolonged idling causes the cylinders to overheat, and inadequate lubrication accelerates part wear. Now, I've changed my driving habits: I only briefly press the accelerator to match revs during gear shifts, and operate the car properly the rest of the time.
