A control apparatus for an internal combustion engine (10) of this invention includes: a turbo-supercharger (22); an exhaust gas purifying catalyst (38) disposed in an exhaust passage (16) on the downstream side of a turbine (22b); and a WGV (42) capable of opening and closing an exhaust bypass passage (40) that bypasses the turbine (22b). At the time of a catalyst warm-up request, catalyst warm-up control that opens the WGV (42) and retards the ignition timing is executed. If the sensitivity of control of an intake air amount by the throttle valve (30) is high, the intake air amount is controlled using the throttle valve (30) during execution of the catalyst warm-up control. If the control sensitivity is low, the intake air amount is controlled using the WGV (42) during execution of the catalyst warm-up control. When the WGV degree of opening is controlled toward a closed side during execution of the intake air amount control using the WGV (42), a retard amount of the ignition timing is increased. |
