Abstract
A turbocharger has a turbine housing scroll that is meridionally divided into first and second scrolls. A nozzle ring disposed in the turbine nozzle has an array of circumferentially spaced first vanes and an array of circumferentially spaced second vanes. The first vane passages between first vanes are configured to blow exhaust gas onto the turbine blade leading edges. Likewise, the second vane passages are configured to blow exhaust gas on the turbine blade leading edges. The first and second vanes are circumferentially staggered relative to each other such that the turbine blade leading edges receive exhaust gas from the first and second blade passages in interleaved fashion about a circumference of the turbine wheel.
