What happens when you press the accelerator while depressing the clutch?

[JuneAnn]

Pressing the accelerator while depressing the clutch will cause clutch wear, increase engine speed, amplify noise, but the vehicle won't move. Prolonged operation with the engine speed indicator in the red zone may lead to engine seizure. Here's the correct procedure: 1. After starting the engine, depress the clutch pedal, engage the gear, and release the handbrake. 2. Apply slight throttle while gradually releasing the clutch. The key technique is: gradually release the clutch with your left foot while simultaneously increasing throttle with your right foot. When you hear (primarily feel) the engine speed drop, continue releasing the clutch while progressively increasing throttle. 3. After fully releasing the clutch, maintain steady throttle. 4. Once the vehicle gains speed and you sense sufficient engine RPM reserve, you may proceed to shift gears.
