    Abstract: A turbocharger (20) includes ported shroud compressor housing (28) disposed about compressor wheel (36) having 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 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 recirculation slot (80) and inlet re-entry slot (82) for reentry of airflow into inlet section (56). The ring (60) has inner wall surface (66) defining first section (84) extending axially along longitudinal axis (A) proximate to 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) radially away from and along longitudinal axis (A) and distal to compressor wheel (36). The inlet section (56) has first diameter (Dl) and third section (88) has second diameter (D2) being either one of equal to or less than first diameter (Dl).

    Abstract: A laser cutting device (100) is configured to etch an inner surface of a journal bearing (18). The laser cutting device (100) includes a laser (102); a beam directing tool (130) that receives a beam (108) emitted from the laser (102) and selectively changes the direction of travel of the beam (108); a fixture (170) that supports the journal bearing (18) in a desired position relative to the beam directing tool (130); an actuator (148) connected to one of the beam directing tool (130) and the fixture (170), the actuator (148) providing relative movement between the beam directing tool (130) and the fixture (170); and a controller (180) that controls the intensity and duration of the beam (108) emitted from the laser (102); and the actuator (148), whereby material can be removed from a surface of the journal bearing (18) to a precise width and depth, and in any pattern.
