Electronic throttle control (ETC) is an automobile technology that uses electronics to replace the traditional mechanical linkages between the driver's input such as a foot pedal to the vehicle's throttle mechanism which regulates speed or acceleration. This concept is often called drive by wire, [1][2] and sometimes called accelerate-by-wire ...
Throttle response or vehicle responsiveness is a measure of how quickly a vehicle's prime mover, such as an internal combustion engine, can increase its power output in response to a driver's request for acceleration. Throttles are not used in diesel engines, but the term throttle can be used to refer to any input that modulates the power ...
Throttle. A throttle is a 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 ...
An unresponsive accelerator pedal may result from incursion: i.e., blockage by a foreign object or any other mechanical interference with the pedal's operation — and may involve the accelerator or brake pedal. A design flaw in some Toyota models enabled accelerator pedals to become trapped by floor mats. [18]
Therefore, an accelerator pump is often used to briefly provide extra fuel as the throttle is opened. [12] When the driver presses the throttle pedal, a small piston or diaphragm pump injects extra fuel directly into the carburetor throat. [13] The accelerator pump can also be used to "prime" an engine with extra fuel prior to attempting a cold ...
Left-foot braking. Left-foot braking is the technique of using the left foot to operate the brake pedal in an automobile, leaving the right foot dedicated to the throttle pedal. [1] It contrasts with the practice of using the left foot to operate the clutch pedal, leaving the right foot to share the duties of controlling both brake and gas pedals.
