<p>A turbocharger turbine housing of this invention comprises a generally circular-shaped body having an exhaust gas inlet flange at a radial housing end and an exhaust gas outlet at an axial end. The inlet flange is configured having openings to two volutes that are separated by a wall divider, thereby forming an X-shaped pattern. The inlet flange is additionally configured having rounded and uniform thickness walls. The volutes are configured having a nonuniform shape and size, and the wall divider is configured having a diminishing area between the volutes, moving through the housing away from the inlet flange. The volutes are configured having a nonuniform shape and size with respect to one another as well moving through the turbine housing. Configured in this manner, turbocharger turbine housings of this invention serve to minimize thermal stress effects caused from transient thermal loading, thereby minimizing and/or eliminating thermal stress relating damage such as cracking.</p> |
