Abstract

A fuel injection control apparatus for an internal combustion engine using a hot-wire type air flow sensor wherein, even during a low engine speed and in a fully opened condition of the throttle valve of the engine, the output of the air flow sensor is corrected corresponding to the opening of the throttle valve and the engine speed on the basis on a predetermined relationship therebetween, thereby providing a proper A/F ratio.
