A control apparatus of an internal combustion engine performs control to warm up a catalyst. More specifically, the control apparatus keeps a wastegate valve open when the temperature of the catalyst is less than a predetermined temperature and closes the wastegate valve when the temperature of the catalyst becomes equal to or greater than the predetermined temperature. The control apparatus executes control to increase and decrease the fuel injection quantity such that the internal combustion engine alternately switches between lean burn and rich burn when the wastegate valve is closed. Accordingly, rich gas and lean gas can be reliably mixed in the catalyst, and CO can be reliably combusted in the catalyst. Therefore, the catalyst can be promptly warmed up while CO, HC, and the like can be appropriately suppressed from flowing through the catalyst.
