Abstract: An internal combustion engine defines a plurality of cylinders including full-time active cylinders and cylinders capable of being deactivated. A turbocharger having a twin scroll turbine includes a first turbine scroll in communication with the exhaust passages from the full-time active cylinders and a second turbine scroll in communication with the exhaust passages from the cylinders capable of being deactivated. A scroll control valve is provided in communication with the exhaust passages from the cylinders capable of being deactivated and being operable in an open position to allow exhaust gases from the cylinders capable of being deactivated to pass through the second turbine scroll, and being operable in a closed position to direct exhaust gases from the plurality of second cylinders capable of being deactivated to pass through the first turbine scroll.
