Here's how it works:
1. Engine Power: The engine generates power through combustion, turning the crankshaft.
2. Clutch Engagement: When you depress the clutch pedal, the clutch disconnects the engine from the transmission. When you release the clutch, it engages, connecting the engine to the transmission.
3. Power Transfer: The engine's power is transferred to the transmission through the clutch.
4. Input Shaft Rotation: The connected clutch spins the input shaft of the gearbox, which is directly connected to the clutch.
Essentially, the engine is the source of power, and the clutch acts as a connector, allowing the engine's rotational force to be transmitted to the gearbox input shaft. This initiates the gear selection process and ultimately allows the car to move.
