Abstract
A turbocharger turbine housing with at least two volutes utilizing multiple nozzle rings to optimize the turbocharger's proficiency per application, and a valve to control the exhaust flow to selected volutes in the turbine housing.
Claims18
An exhaust-gas turbine assembly for use with a turbocharger, comprising:
- a turbine housing having an exhaust inlet side and an exhaust outlet side, the turbine housing receiving exhaust gases from an internal combustion engine through at least one exhaust gas inlet conduit on the exhaust inlet side of the housing;
- a plurality of nozzle rings, interchangeable with one another;
- one of the plurality of nozzle rings positioned in communication with at least one volute gas chamber encompassing the nozzle ring, the nozzle ring having a polar array of vanes extending therefrom, the vanes directing exhaust gases around or against a periphery of one or more turbine wheels to cause rotation of the one-or-more turbine wheels;
- a retainer ring, retaining the nozzle ring within the turbine housing;
- an exhaust gas outlet port positioned on the exhaust outlet side of the turbine housing, the exhaust gases passing through the exhaust gas outlet after passing around or against the periphery of the one or more turbine wheels;
- and
- the nozzle ring and the retainer ring being installable and removable through the exhaust gas outlet port on the exhaust outlet side of the turbine housing.

A tunable exhaust-gas turbine assembly for use with a turbocharger, comprising:
- a turbine housing having an exhaust inlet side and an exhaust outlet side, the turbine housing receiving exhaust gases from an internal combustion engine through at least one exhaust gas inlet conduit on the exhaust inlet side of the housing;
- a plurality of nozzle rings, interchangeable with one another:
- one of the plurality of nozzle rings positioned in communication with at least one volute gas chamber encompassing the at least one nozzle ring, the nozzle ring having a polar array of vanes extending therefrom, the vanes directing exhaust gases around or against a periphery of one or more turbine wheels to cause rotation of the one-or-more turbine wheels;
- a retainer ring, retaining the nozzle ring within the turbine housing;
- an exhaust gas outlet port positioned on the exhaust outlet side of the turbine housing, the exhaust gases passing through the exhaust gas outlet after passing around or against the periphery of the one or more turbine wheels;
- and
- wherein performance characteristics of the turbocharger can be tuned while the turbocharger remains installed on a vehicle by selectively replacing the nozzle ring with a nozzle ring having different performance characteristics.

An exhaust-gas turbine assembly for use with a turbocharger, comprising:
- a turbine housing having an inlet side and an outlet side, the turbine housing receiving exhaust gases from an internal combustion engine through at least one exhaust gas inlet conduit on the inlet side of the housing;
- a plurality of nozzle rings, interchangeable with one another;
- at least three of the interchangeable nozzle rings positioned adjacent one another and in communication with at least three volute gas chambers encompassing the at least three nozzle rings, the nozzle rings each having a polar array of vanes extending therefrom, the vanes directing exhaust gases around a periphery of one or more turbine wheels to cause rotation of the one-or-more turbine wheels;
- a retainer ring, retaining the at least three nozzle rings within the turbine housing;
- and an exhaust gas outlet port positioned on the exhaust outlet side of the turbine housing, the exhaust gases passing through the exhaust gas outlet after passing around or against the periphery of the one or more turbine wheels.
