Abstract: A turbocharger (20) includes ported shroud compressor housing (28) disposed about a compressor wheel (36), having an air inlet passage (33) extending axially along and circumferentially about a longitudinal axis (A), volute base portion (50) operably adjacent to compressor wheel (36), contour (52) that encircles and complementarily matches compressor wheel (36), inducer (54) including ring (60) and plurality of extending members (62), inlet section (56) extending from volute base portion (50), and recirculation cavity (70) formed in volute base portion (50) and inlet section (56) with a recirculation slot (80) and inlet re-entry slot (82) for reentry of airflow into inlet section (56). The ring (60) has an inner wall surface (66) defining a first section (84) extending axially along the longitudinal axis (A) and proximate to the compressor wheel (36), second section (86) extending from first section (84) radially away from longitudinal axis (A), and third section (88) extending from second section (86) along longitudinal axis (A) and distal to the compressor wheel (36). The inlet section (56) has a first diameter (D1) and third section (88) has a second diameter (D2) greater than first diameter (D1).

Abstract: A turbocharger (20) includes a turbine wheel portion (36) to receive exhaust gas from an internal combustion engine, a turbocharger shaft (40) coupled to and rotatable by the turbine wheel portion, the turbocharger shaft extending along a longitudinal axis, and a compressor wheel portion (38) coupled to and rotatable by the turbocharger shaft. The compressor wheel portion includes a symmetrical leading edge region (54) facing airflow and an imbalance correction region (56) 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.
