ABSTRACT:
A control apparatus for the internal combustion engine includes a fuel cut post-return fuel increasing correction unit for performing a fuel increasing correction during a specified period when a fuel supply stop state by an fuel cut control unit is returned to a fuel supply state, and a fuel increasing correction stop unit which compares an integrated value of an amount of air flowing into a three-way catalyst during a period of the fuel supply stop with an integrated value of an amount of air flowing into the three-way catalyst during the fuel increasing correction after a fuel supply return, and stops the fuel increasing correction of the fuel cut post-return fuel increasing correction unit when a comparison value reaches a specified value.
