What is throttle meaning?

Throttle refers to the mechanism that regulates the flow of fuel to the engine of a vehicle or machine. This mechanism is generally controlled by the driver or operator, and is used to adjust the engine speed or power output. In cars and motorcycles, the throttle is typically controlled through a pedal or hand lever. In aviation, the throttle is a lever that adjusts the power and speed of the aircraft's engine. The term 'throttle' is derived from the old English word 'thrawan' meaning to 'twist' or 'turn'.
