Throttle

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 (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. 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.

Internal combustion engines

In a gasoline internal combustion engine, the throttle is a valve that directly regulates the amount of air entering the engine, indirectly controlling the charge (fuel + air) burned on each cycle due to the fuel-injector or carburetor maintaining a relatively constant fuel/air ratio. In a motor vehicle the control used by the driver to regulate power is sometimes called the throttle pedal, as it controls the throttle opening, although "accelerator pedal" is more accurate, since not all vehicles have throttles. A diesel engine does not have a throttle; its power level is controlled by regulating the fuel flow into the engine, thus "throttle" and "gas pedal" are both inaccurate terms when applied to a diesel engine.

Throttle (film)

Throttle (also known as No Way Up) is a 2005 American thriller film starring Grayson McCouch. Other cast members include Adrian Paul and Amy Locane. It was filmed entirely in Denver, Colorado.

Plot

Financial analyst Tom Weaver (Grayson McCouch) is a troubled man. He has recently broken off a potential affair with a co-worker named Rebecca. He is also arguing with himself if he wants to continue with a shady ten million dollar business deal with his boss. He has also discovered identical motel keys in his wife, Molly's purse and his boss's car, leading him to believe that she is having an affair. He confronts her about it and she denies this. He lies to her about where he is going and heads to his building to complete the deal to hopefully get himself rich.

Throttle (novella)

Throttle is a novella written in co-authorship by Stephen King and his son Joe Hill. It was published in February 2009 by Gauntlet Press in a limited edition anthology honoring Richard Matheson titled He Is Legend, and in a mass-market audiobook titled Road Rage, also containing Matheson's short story "Duel", which served as inspiration for Throttle. A comic book adaptation by IDW Publishing was published in the spring of 2012.
