ABSTRACT:
An electronically controlled fuel injection apparatus in which opening degree of a throttle valve or throttle aperture is sampled periodically at a predetermined time interval to detect change in the throttle aperture for determining deceleration. Upon every determination of the deceleration, a correcting quantity is accumulatively determined so that deceleration is corrected for compensating delay in the control of fuel injection in dependence on magnitude of change in the throttle aperture. An improved engine performance and optimum air-fuel ratio control can be accomplished.
