Abstract

A system includes a dual volute turbocharger and a controller. The dual volute turbocharger includes a turbine housing. The turbine housing includes a wall, a valve seat, and an interior surface defining a turbine housing interior, a first volute, a second volute, and a turbine housing outlet. The dual volute turbocharger also includes at least one valve member engageable with at least one of the valve seat and the wall of the turbine housing. The at least one valve member and the wall of the turbine housing collectively define a first cross-sectional flow area. The at least one valve member and the valve seat of the turbine housing collectively define a second cross-sectional flow area. The controller is adapted to control the at least one valve member to have an area ratio constant operating range according to a brake-specific fuel consumption of the internal combustion engine.
