Throttle , Valve for regulating the supply of a fluid as steam to an engine, especially the valve controlling the volume of vaporized fuel delivered to the cylinders of an internal-combustion engine. In an automobile engine, gasoline is held in a chamber above the carburetor. Air flows down through the throat of the carburetor, past the throttle valve, and into the intake manifold.
A throttle is the mechanism by which fluid flow is managed by constriction or obstruction. An engine 's power can be increased or decreased by the restriction of inlet gases by the use of a throttle , but usually decreased. The term throttle has come to refer, informally, to any mechanism by which the power or speed of an engine is regulated, such as a car's accelerator pedal.
