Abstract:
1. A control apparatus for an internal combustion engine, comprising: an increasing unit which increases a fuel injection amount under a predetermined condition; an air/fuel ratio feedback control unit which controls the fuel injection amount based on an output of an oxygen concentration sensor; a control unit which decreases an increase amount of the fuel injection amount by the increasing unit when the air/fuel ratio feedback unit corrects the increase amount of the fuel injection amount by the increasing unit, if the increasing unit increases the fuel injection amount during an air/fuel ratio feedback control by the air/fuel ratio feedback control unit; and a purge control unit which inhibits a purge of a canister while the increasing unit increases the fuel injection amount during an air/fuel ratio feedback control, and executes the purge of the canister immediately after the control unit decreases the increase amount of the fuel injection amount.
