The clutch pedal needs to be used when starting or changing gears. The clutch is located between the engine and the gearbox. The clutch can connect or disconnect the engine and the gearbox. The brake pedal is used to control the brake system, and the car will slow down after stepping on the brake pedal. The accelerator pedal is the pedal that needs to be used when accelerating. The accelerator pedal does not directly control the fuel injection volume, but controls the throttle opening. After the throttle opening increases, the ECU will detect it, so that the fuel injection volume will increase. When using the clutch pedal, you need to have certain skills. When the car starts, you need to use semi-linkage skills. If you quickly lift the clutch pedal when starting, it will cause the engine to stall.
