Why is there a throttle when we already have a clutch?

[SanAbigail]

Clutch and throttle are two completely different concepts, and they cannot substitute for each other. Here are the relevant explanations: 1. Function of the clutch: The clutch is located inside the flywheel housing between the engine and the transmission. The clutch assembly is fixed to the rear plane of the flywheel with screws, and the output shaft of the clutch is the input shaft of the transmission. During driving, the driver can press or release the clutch pedal as needed to temporarily separate or gradually engage the engine and the transmission, thereby cutting off or transmitting the power from the engine to the transmission. 2. Function of the throttle: The throttle controls the opening of the carburetor's throttle valve to regulate the filling amount of the cylinder, thereby determining the engine's output power.
