Recovery from sulfur poisoning, etc. in exhaust purification catalyst are effectively carried out through appropriate control of multiple exhaust valves. A control unit of internal combustion engine performs control of an internal combustion engine adapted for lean burn. An exhaust system of internal combustion engine includes a first exhaust valve and second exhaust valve respectively fitted to multiple cylinders; a first exhaust passageway communicating with the first exhaust valve; a second exhaust passageway communicating with the second exhaust valve; a first exhaust purification catalyst disposed on at least either the first exhaust passageway or the second exhaust passageway; and a second exhaust purification catalyst disposed on the exhaust passageway after confluence. Control means controls the exhaust valves so that in rich burn, the enriching effect appears more in the second exhaust purification catalyst than in the first exhaust purification catalyst. Consequently, complete consumption of exhaust gas by the first exhaust purification catalyst can be inhibited, and the temperature of the second exhaust purification catalyst can be effectively raised. Therefore, recovery from sulfur poisoning, etc. can be effectively carried out.
