Abstract

A control apparatus for an internal combustion engine according to the invention is applied to an internal combustion engine in which EGR gas and condensed water generated by an EGR cooler are supplied into a cylinder. The control apparatus calculates an equivalence ratio of the internal combustion engine, and controls an EGR valve and a condensed water supply valve such that, when the equivalence ratio is high, a supply rate of the condensed water increases and a supply rate of the EGR gas decreases relative to when the equivalence ratio is low.
