Abstract

A fuel injection control apparatus for an engine, which makes an appropriate increasing correction to a fuel amount at the time of restart after the stop period of the engine, thereby making it possible to cut down on the amounts of NOx emissions, is provided. The fuel injection control apparatus comprises an injection volume control unit for controlling a fuel injection volume, a supplied oxygen amount detection unit for detecting a supplied oxygen amount, an activity determination unit for determining whether or not an exhaust purification catalyst is in an active state, and an amount increasing correction unit for making an increasing correction to the fuel injection volume in accordance with the detection results of the supplied oxygen amount detection unit and the determination results of the activity determination unit.
