Abstract
A turbine includes a turbine housing having two gas passages of substantially the same flow area. A nozzle ring is disposed in the housing and around the turbine wheel. The nozzle ring includes first and second outer rings, and an inner ring disposed between the first and second outer rings. First and second pluralities of vanes are disposed between the rings. The second outer ring has a thicker cross section than the first outer ring such that a larger flow area is created between the first outer ring and the inner ring than a flow area created between the second outer ring and the inner ring.
