PROBLEM TO BE SOLVED: To provide a control device of a hydrogeneration internal combustion engine which can suppress the occurrence of HC and CO while effectively utilizing hydrogen. SOLUTION: When the output of an oxygen sensor 72 provided to an exhaust passage 40 indicates a rich state, the injection amount of fuel from each injector 50, 60 is corrected so as to make a cylinder air-fuel ratio lean. When the output of the oxygen sensor 72 indicates lean, the injection amount of fuel from each injector 50, 60 is corrected so as to make a cylinder air-fuel ratio rich. In this case, the hydrogeneration ratio in case where the output of the oxygen sensor 72 indicates rich is increased more than that in case where the output of the oxygen sensor 72 indicates lean.
