Abstract
A turbocharger includes a turbine wheel portion to receive exhaust gas from an internal combustion engine, a turbocharger shaft coupled to and rotatable by the turbine wheel portion, the turbocharger shaft extending along a longitudinal axis, and a compressor wheel portion coupled to and rotatable by the turbocharger shaft. The compressor wheel portion includes a symmetrical leading edge region facing airflow and an imbalance correction region disposed longitudinally inboard from the symmetrical leading edge region and extending radially inward to correct an imbalance of the turbocharger shaft and to reduce aero-acoustic noises.
