In a fuel-injected engine, the throttle valve is placed on the entrance of the intake manifold, or housed in the throttle body.

The throttle on a gasoline engine is typically a butterfly valve. This means that the operator does not have direct control over the flow of fuel and air the Engine Control Unit (ECU) can achieve better control in order to reduce emissions, maximize performance and adjust the engine idle to make a cold engine warm up faster or to account for eventual additional engine loads such as running air conditioning compressors in order to avoid engine stalls.
#Definition of throttled driver#
Modern engines of both types (gas and diesel) are commonly drive-by-wire systems where sensors monitor the driver controls and in response a computerized system controls the flow of fuel and air. The further the pedal is pushed, the wider the throttle valve opens. This arm is usually directly linked to the accelerator cable, and operates in accordance with the driver, who hits it. The butterfly valve of the throttle is operated by means of an arm piece, loaded by a spring.

Historically, the throttle pedal or lever acts via a direct mechanical linkage. The throttle of a diesel, when present, regulates the air flow into the engine. In a gasoline direct injection engine, the throttle regulates the amount of air allowed to enter the engine. For a gasoline engine, the throttle most commonly regulates the amount of air and fuel allowed to enter the engine. In a motor vehicle the control used by the driver to regulate power is sometimes called the throttle, accelerator, or gas pedal. In an internal combustion engine, the throttle is a means of controlling an engine's power by regulating the amount of fuel or air entering the engine.
