Abstract

A turbocharger for an internal combustion engine is provided with a compressor having an inlet receiving combustion gas and an outlet; and a turbine drivingly coupled to the compressor. The turbine has a shaft and a turbine wheel disposed on the shaft. The turbine wheel has a plurality of turbine blades and an edge defining a plurality of scallops. Scallop fillers are disposed between the turbine blades. Advantages of a scalloped turbine wheel, resulting from reductions in mass, are achieved without reductions in efficiency normally experienced with scalloped turbine wheels.
