Beschreibung
Zusammenfassung:	A system includes a divided volute turbocharger that delivers compressed air to an internal combustion engine and receives exhaust gas from the internal combustion engine. The turbocharger includes a turbine housing, a first and second volute, and a turbine housing outlet. The system also includes turbine wheel disposed in the turbine housing and a vane ring disposed in the turbine housing between the turbine wheel and the volutes. The vane ring includes a plurality of vanes having an asymmetric vane pattern disposed on a vane ring surface of an annular disk that receives the turbine wheel therewithin to direct and control the flow of exhaust from the volutes into the turbine wheel with generally equal flow while significantly reducing HCF forcing function.
