Beschreibung
Zusammenfassung:	A turbocharger for internal combustion engines, having a heat shield (360) disposed between a turbine housing (110') and center housing (340) of the turbocharger for shielding the center housing (340) from exhaust gases passing through the turbine. The heat shield in one embodiment is centered on a generally conical surface of the center housing, by engagement between the conical surface and a centering portion of the heat shield. In another embodiment, the heat shield has a generally conical portion that is non-axisymmetric, having a plurality of radially enlarged lobes that engage a radially inwardly facing surface of the turbine housing for centering the heat shield.
