Abstract
A turbocharger includes a turbine housing defining a turbine housing interior, a turbine wheel disposed within the turbine housing interior, a shaft coupled to and rotatable by the turbine wheel, a compressor housing defining a compressor housing interior and a flow path, and a compressor wheel disposed within the compressor housing interior and coupled to the shaft. The compressor wheel has a hub coupled to the shaft, and a plurality of impeller blades extending radially from the hub. The plurality of impeller blades define an inducer end having an inducer diameter, and an exducer end having an exducer diameter greater than the inducer diameter. The inducer diameter and the exducer diameter establish a compressor trim. The compressor wheel also has a compressor wheel shroud disposed about the plurality of impeller blades. The compressor wheel shroud encloses the plurality of impeller blades to define a shroud interior.
