What are the functions of the clutch and throttle of a car?

Clutch and throttle are two completely different concepts. The function of the clutch is to cut off the power transmission between the engine and the gearbox, which is convenient for the driver to shift gears. Throttle means that the driver controls the engine speed or the amount of air entering the engine combustion chamber within a certain range.

The clutch is located in the flywheel housing between the engine and the gearbox. The clutch assembly is fixed on the rear plane of the flywheel with screws, and the output shaft of the clutch is the input shaft of the gearbox. When the car is running, the driver can step on or release the clutch pedal as needed, so that the engine and gearbox are temporarily separated and gradually engaged, thus cutting off or transmitting the power input from the engine to the gearbox. Clutch is a common component in mechanical transmission, which can be separated or engaged at any time. Its basic requirements are: smooth joint, rapid and complete separation; Convenient adjustment and maintenance; Small overall size; Small mass; Good wear resistance and sufficient heat dissipation capacity; The operation is convenient and labor-saving, and the common ones are claw type and friction type.

Throttle, also known as "throttle" and "throttle". Refers to the control device that controls the engine power (thrust). On the piston aero-engine, the throttle valve controls the opening of the carburetor to control the filling amount of the cylinder, thus determining the output power of the engine. On the gas turbine engine, the throttle valve controls the metered fuel flow of the fuel regulator, thus determining the thrust generated by the engine. The position of the throttle is controlled by the driver operating the throttle lever in the cockpit, and it is transmitted to the carburetor or fuel regulator on the engine through control system components such as pull rod, rocker arm, torsion tube, steel cable, pulley and sector wheel. On an airplane, the throttle lever is always pushed forward to increase power (thrust) and pulled back to decrease power (thrust).
