Abstract
A control apparatus for an internal combustion engine according to the invention is applied to an internal combustion engine that is equipped with an exhaust gas treatment device that is provided in an exhaust passage, and a burner device that is provided in the exhaust passage upstream of the exhaust gas treatment device so as to raise a temperature of exhaust gas supplied to the exhaust gas treatment device. The control apparatus performs an increase control for increasing a concentration of oxygen in exhaust gas supplied to the burner device if the concentration of oxygen is not higher than a predetermined required concentration of oxygen when there is a request to operate the burner device. The combustion performance of the burner device is stably ensured by securing or compensating for an insufficient concentration of oxygen.
