<p><P>PROBLEM TO BE SOLVED: To provide a control device for an internal combustion engine capable of reducing THC and NOx in a high rotation region of the medium-high load of an internal combustion engine in a control device for an internal combustion engine equipped with a supercharger. <P>SOLUTION: This device is provided with a turbo supercharger 24 disposed in an intake passage 28 of the internal combustion engine, a first intake throttle valve 36 arranged in the upstream side of the turbo supercharger 24 in the intake passage 28, and a second intake throttle valve 38 arranged in the downstream side of the turbo supercharger 24 in the intake passage 28. In the medium-high load region of the internal combustion engine, when it is determined that engine speed is in the high rotation region equal to or higher than a prescribed value, an intake air amount is controlled mainly by using the first intake throttle valve 36. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
