What Does the Left Foot Control in a Manual Transmission?

[RoseFitz]

Left foot controls the clutch pedal. The clutch pedal has functions and working principles. Functions of the clutch pedal: Through proper operation by the driver, it achieves the engagement and disengagement between the front and rear parts of the clutch (engine and transmission). It indirectly enables: starting, gear shifting, reversing, and braking. Working principle: The clutch consists of friction plates, spring plates, pressure plates, and power output shafts, arranged between the engine and the gearbox. It transmits the torque stored on the engine flywheel to the transmission, ensuring that the vehicle delivers appropriate driving force and torque to the drive wheels under different driving conditions, falling under the category of the powertrain. During semi-engagement, the clutch allows a speed difference between the power input end and the power output end, meaning it transmits the appropriate amount of power through this speed difference.
