Throttle

By Andy Y, January 20, 2009

The throttle is a round metal "butterfly" blade that resides inside the round "bore" of the throttle body and controls the amount of air that is allowed to enter a gasoline engine. The opening/closing of this blade is controlled by a cable attached to the throttle pedal or by a computer-controlled electronic throttle motor.
