Turbine

A turbine housing for a turbine, the turbine housing comprising:

• an inlet configured to receive exhaust gas;
• a wheel cavity configured to receive a turbine wheel;
• an outlet in fluid communication with the inlet;
• an outer wall extending at least partway between the inlet and the outlet;
• and
• a dosing structure configured to receive, and expel, reductant;
• wherein at least part of the dosing structure is integrally formed with, and projects from, the outer wall.

A turbine assembly comprising:

• a turbine, the turbine comprising a turbine housing and a turbine wheel, the turbine housing comprising:
• an inlet;
• a wheel cavity that receives the turbine wheel, the wheel cavity being disposed downstream of the inlet;
• and
• an outlet, the outlet being disposed downstream of the wheel cavity;
• and
• an adapter element coupled to the outlet of the turbine housing, the adapter element defining a longitudinal axis and comprising:
• a first connection portion coupled to the outlet of the turbine;
• a second connection portion configured to engage a conduit;
• an outer wall that extends between the first and second connection portions, the outer wall defining an inner surface and an outer surface;
• and
• a dosing structure configured to receive, and expel, reductant.
