Abstract: A turbocharger for a power system is disclosed. The turbocharger has an impeller wheel, which is rotatable about a central axis and includes a back face at least partially defining a reference plane substantially perpendicular to the central axis. In addition, the turbocharger includes a housing configured to at least partially enclose the impeller wheel. The housing also has at least one volute configured to fluidly communicate fluid with the impeller wheel. The entire length of the at least one volute from a turbocharger inlet is axially inclined relative to the reference plane so the fluid flows in both a radial and axial direction.

Abstract: A turbocharger for a power system is disclosed. The turbocharger has a turbine wheel and a housing configured to at least partially enclose the turbine wheel. The housing has a first turbine volute configured to fluidly communicate exhaust gases with the turbine wheel, a second turbine volute configured to fluidly communicate exhaust gases with the turbine wheel, a wall member axially separating the first and second turbine volutes. The housing also has a first plurality of annularly disposed vane members associated with at least one of the first and second turbine volutes.
