CONTROL APPARATUS FOR INTERNAL COMBUSTION ENGINE

When a performance flag of a temperature raising process becomes “1”, a CPU increases an injection amount for first, third and fourth cylinders from a base injection amount for making an air-fuel ratio of an air-fuel mixture equal to a theoretical air-fuel ratio, by an increase amount, and stops combustion control in a second cylinder. The CPU gradually increases a ratio of the increase amount to the base injection amount, at the start of the temperature raising process.
