Abstract
In an electronic fuel injection system for an internal combustion engine, a throttle position sensor provides an output pulse with a duration corresponding to the time interval during which throttle is nearly closed. The output from the throttle position sensor is nullified when the pulse duration is smaller than a predetermined value to prevent fuel cut-off during brief closure of throttle during transmission gear changes. The output from the throttle position sensor is used to cut off fuel only when the throttle closure time extends beyond the predetermined time interval.
