Definition & Meaning of "accelerator pedal"in English

What is the "accelerator pedal"?

The accelerator pedal is a foot-operated control in a vehicle that regulates the engine's speed. Pressing the pedal increases the amount of fuel entering the engine, causing the vehicle to speed up. Releasing the pedal reduces the fuel flow, slowing the vehicle down. The accelerator pedal is typically located on the right side of the area where the driver's feet rest, next to the brake pedal, and is essential for controlling the vehicle's acceleration and maintaining the desired speed.
