Abstract
An electronically controlled fuel injection apparatus for internal combustion engine which increases the rate of fuel injection when the engine speed drops by a rate more than a predetermined rate under a condition that the aperture of the throttle valve is minimum, that is, under an idling condition. In order to increase the rate of fuel injection, the width of the basic fuel injection pulse is enlarged which is given according to the engine speed and the intake air flow rate, or, in addition to the basic fuel injection pulse, a predetermined rate of fuel is injected asynchronously, i.e., independently from the crank angle of the engine.
