Control apparatus for internal combustion engine

A control apparatus for an internal combustion engine, the control apparatus being applied to an internal combustion engine having a plurality of cylinders and performing a base injection amount calculation process for calculating a base value of an injection amount of fuel injection valves that supply fuel to the cylinders respectively, a correction process for correcting the injection amount from the base value, and an injection valve operation process for operating the fuel injection valves in accordance with an output of the correction process, wherein

• the correction process includes a low-temperature increase process, a feedback process, and a stop decrease process,
• the low-temperature increase process is a process of correcting the injection amount in an increasing manner when an increase index value that is an index value of a temperature of the internal combustion engine is smaller than a threshold,
• the feedback process is a process of correcting the injection amount to control an air-fuel ratio of an air-fuel mixture in the cylinders of the internal combustion engine to a target air-fuel ratio in a feedback manner, and
• the stop decrease process is a process of correcting the injection amount in a decreasing manner when a decrease index value that is an index value of the temperature of the internal combustion engine is smaller than a predetermined value and the feedback process is stopped.
