Why does the car move when the clutch is released?

When the gear is engaged and the clutch is gently lifted, the engine's power output is transferred to the transmission and the drive wheels, causing the vehicle to move. Principle: The engine crankshaft drives the flywheel to rotate, and the flywheel drives the friction plate to rotate. The other end of the friction plate is connected to the transmission. The clutch is the mechanism that separates the friction plate from the flywheel. When the driver lifts the clutch, the pressure plate presses against the friction plate, and the flywheel drives the friction plate to move, which in turn causes the car to move, albeit very slowly at the start. Theoretically, as long as the engine is running, pressing or not pressing the accelerator only affects the amount of power output, not whether power is output or not. However, this power is smaller than when the accelerator is pressed, so it is easy for the engine to stall due to the static resistance of the vehicle. If the clutch is lifted gently without stalling the engine, the vehicle can obtain forward momentum. Function of the clutch: The clutch is the component in the car's transmission system that is directly connected to the engine. It is responsible for the disconnection and connection of power and the transmission system, ensuring smooth starting of the car and smooth gear shifting, while also preventing overload of the transmission system.
