<P> An engine 's power can be increased or decreased by the restriction of inlet gases ( i.e. , by the use of a throttle ) , but usually decreased . The term throttle has come to refer , informally and incorrectly , to any mechanism by which the power or speed of an engine is regulated , such as a car 's accelerator pedal . What is often termed a throttle ( in an aviation context ) is more correctly called a thrust lever , particularly for jet engine powered aircraft . For a steam engine , the steam valve that sets the engine speed / power is often known as a regulator . </P>
