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.
Claims20
A turbocharger, comprising:
- a turbine wheel;
- and
- a housing configured to at least partially enclose the turbine wheel and having:
- a first turbine volute configured to fluidly communicate exhaust with the turbine wheel;
- a second turbine volute configured to fluidly communicate exhaust with the turbine wheel;
- a wall member axially separating the first and second turbine volutes;
- and
- a first plurality of annularly disposed vane members associated with at least one of the first and second turbine volutes.
A method of operating a turbocharger, comprising:
- receiving a first flow of exhaust into the turbocharger;
- simultaneously receiving a second flow of exhaust into the turbocharger at an axially offset location separate from the first;
- and
- radially redirecting at least one of the first and second flows of exhaust at a plurality of finite annular locations.
A power system, comprising:
- a power source having a plurality of combustion chambers and being configured to produce a power output and a flow of exhaust gases;
- a first exhaust passageway associated with at least a first of the plurality of combustion chambers;
- a second exhaust passageway associated with at least a second of the plurality of combustion chambers;
- and
- a turbocharger in fluid communication with the first and second exhaust passageways, the turbocharger including:
- a turbine wheel;
- and
- a housing configured to at least partially enclose the turbine wheel and having:
- a first turbine volute configured to fluidly communicate the exhaust gases with the turbine wheel;
- a second turbine volute configured to fluidly communicate the exhaust gases with the turbine wheel;
- a wall member axially separating the first and second turbine volutes;
- a first plurality of annularly disposed vane members associated with the first turbine volute;
- and
- a second plurality of annularly disposed vane members associated with the second turbine volute.
