A control apparatus for an internal combustion engine includes a first exhaust passage through which an exhaust gas of a first cylinder group flows, a second exhaust passage through which an exhaust gas of a second cylinder group flows, a third exhaust passage formed by merging of the first exhaust passage and the second exhaust passage, a centrifugal supercharger equipped with a turbine arranged in the third exhaust passage, an exhaust gas purification device arranged in the third exhaust passage at a location downstream of the turbine of the centrifugal supercharger, a bypass passage branching from the first exhaust passage, and merging into the third exhaust passage at a location upstream of the exhaust gas purification device, and a waste gate valve for switching opening and closing of the bypass passage, wherein when inter-cylinder-group imbalance processing is carried out, the bypass passage is made to open. |
