Turbocharger with axial turbine stage

A method of handling exhaust from an engine, the method comprising:

• receiving exhaust from an exhaust manifold of the engine at a volute inlet of a turbine in a tangential direction;
• directing exhaust from the volute inlet through an axial channel;
• directing exhaust from the axial channel through a nozzle ring;
• and
• directing exhaust from the nozzle ring through a turbine wheel to drive a compressor wheel connected to the turbine wheel by a shaft.

A power system, comprising:

• an engine;
• an exhaust manifold fluidly connected to the engine;
• a turbocharger fluidly connected to the exhaust manifold, the turbocharger including:
• a housing at least partially defining a compressor shroud and a turbine shroud, the turbine shroud forming a volute having:
• an inlet configured to receive exhaust from the exhaust manifold in a tangential direction;
• and
• an axial channel disposed downstream of the inlet;
• a turbine wheel disposed within the turbine shroud and configured to receive exhaust from the axial channel;
• a compressor wheel disposed within the compressor shroud;
• a shaft connecting the turbine wheel to the compressor wheel;
• and
• a nozzle ring disposed within the axial channel at a location upstream of the turbine wheel.
