Abstract:
Provided is a control apparatus for an internal combustion engine, which can introduce external EGR gas during a cold condition, while favorably suppressing an occurrence of condensed water from the EGR gas. A twin entry type turbo supercharger (18) is provided. A first exhaust passage (14a) through which first exhaust gas exhausted from a first cylinder group (#2 and #3) and a second exhaust passage (14b) through which second exhaust gas exhausted from a second cylinder group (#1 and #4) are provided. A sub cooling system including a sub cooling passage (32) for cooling the first exhaust passage (14a) is provided. A main cooling system including a main cooling passage (30) for cooling the second exhaust passage (14b) is provided. An EGR passage (24) connected between the first exhaust passage (14a) and an intake passage (12), and an EGR valve (26) playing a role in opening and closing the EGR passage (24) are provided. The circulation of sub cooling water in the sub cooling system is stopped when EGR gas is introduced into the intake passage (12) during the cold condition.
