<P>PROBLEM TO BE SOLVED: To appropriately inhibit residence of EGR gas or the like near a secondary turbocharger. <P>SOLUTION: A control device for an internal combustion engine with superchargers supercharges using a primary turbocharger and a secondary turbocharger arranged in parallel with an intake passage and an exhaust passage. Re-circulated exhaust gas is introduced into the intake passage between a branch part of the intake passage and the primary turbocharger. Consequently, EGR gas passes through only a compressor of the primary turbocharger side. Namely, supply of EGR gas to the secondary turbocharger can be inhibited and only fresh air passes through the secondary turbocharger. Consequently, residence of EGR gas near the secondary turbocharger can be appropriately inhibited. <P>COPYRIGHT: (C)2009,JPO&INPIT |
