Abstract: <P>PROBLEM TO BE SOLVED: To provide a control device for an internal combustion engine, capable of further accelerating the activation of an exhaust emission conversion catalyst in comparison with the past.  <P>SOLUTION: Intake pressure rise control is performed (S12) when it is necessary to accelerate the activation of a three-way catalyst 31. That is, when a turbocharger 9 is not operated, the turbocharger is started to be operated, and when the turbocharger is already operated, the opening of a variable vane 9d is controlled to raise supercharging pressure. By raising the supercharging pressure, the flow rate of exhaust emission is increased, and the temperature rise of the three-way catalyst 31 is promoted. Further, exhaust emission is recirculated (S18) through a low-pressure exhaust emission recirculation passage 41 connecting the downstream side of the three-way catalyst 31 to an intake valve 7. Thereby, since the whole amount of the exhaust emission is passed through the three-way catalyst 31 while recirculating exhaust emission, temperature rise is promoted.  <P>COPYRIGHT: (C)2009,JPO&INPIT
