Abstract:
A turbocharger assembly comprising:a turbine housing having an exhaust gas inlet and an exhaust outlet, and a volute connected to the inlet; a turbine wheel carried within the turbine housing and attached to a shaft; a plurality of vanes disposed within the turbine housing between the exhaust gas inlet and turbine wheel, each vane comprising: an inner airfoil surface; an outer airfoil surface oriented opposite the inner airfoil surface, the inner and outer airfoil surfaces defining a vane airfoil thickness; a leading edge positioned along a first inner and outer airfoil surface junction; and a trailing edge positioned along a second inner and outer airfoil surface junction; wherein the inner airfoil and outer airfoil surfaces define a camberline positioned therebetween and extending from the leading edge to the trailing edge, and wherein the camberline includes a curved section, and is substantially flat along at least about the first five percent of the length moving from the leading edge.
