Abstract: A turbocharger includes a turbine housing. The turbine housing includes an interior surface defining a turbine housing interior. The interior surface extends between a turbine housing inlet and a turbine housing outlet. The turbine housing also includes a wastegate duct disposed between the turbine housing inlet and the turbine housing outlet and defining a wastegate channel in fluid communication with the turbine housing inlet and the turbine housing outlet. The turbocharger also includes a valve seat and wastegate assembly including a valve movable between a first position and a second position. The turbocharger further includes a diffuser at least partially surrounding the valve seat for uniformly diffusing the flow of exhaust gas into the turbine housing outlet.

Abstract: 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.
