Abstract

A controller for an internal combustion engine is constructed such that, when detecting a variation in the operating conditions of the engine or acceleration, a lag of fuel injection timing control is predicted. In accordance with a difference between an actual fuel injection timing and the predicted target fuel injection timing, a target EGR area, i.e. EGR amount or rate is corrected.
