<p><P>PROBLEM TO BE SOLVED: To provide a control device for an internal combustion engine with a supercharger, warming up a catalyst by making exhaust gas bypass a supercharger turbine, capable of warming up the catalyst quickly while suppressing deterioration of emission. <P>SOLUTION: The control device for the internal combustion engine with the supercharger is provided with a main exhaust gas passage passing the supercharger turbine and opened to outside air via a catalyst, an exhaust gas bypass passage branching off from a turbine upstream side of the main exhaust gas passage to bypass the supercharger turbine and merging with a main exhaust gas passage in a part before reaching the catalyst on a turbine downstream side, and an exhaust bypass valve provided in the exhaust gas bypass passage. Ignition timing is controlled according to at least one of an engine warming up condition and a catalyst warming up condition before completion of warming up of a main body of the internal combustion engine and warming up of the catalyst, and opening of the exhaust bypass valve is controlled based on control of ignition timing. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
