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.
