<p><P>PROBLEM TO BE SOLVED: To provide a control device for an internal combustion engine, certainly suppressing the local excessive temperature rise of the turbine housing of a twin entry turbocharger. <P>SOLUTION: This control device for the internal combustion engine includes: the turbocharger provided with a turbine having two inlets; a first exhaust passage allowing exhaust gas in a first cylinder group of the internal combustion engine having a plurality of cylinders to flow into one inlet of the turbine; a second exhaust passage allowing exhaust gas in a second cylinder group to flow into the other inlet of the turbine and having a smaller surface area than that of the first exhaust passage; a determination means determining whether or not the operating condition of the internal combustion engine is in a high-exhaust gas temperature range; and an air-fuel ratio correction means performing correction so that an air-fuel ratio of at least one of the cylinders of the second cylinder group is enriched in comparison with a theoretical air-fuel ratio when it is determined that the operating condition is in the high-exhaust gas temperature range. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
