Abstract

An exhaust gas turbocharger for internal combustion engines with a turbine wheel traversed by the exhaust gases radially from the outside toward the inside and with a water-cooled housing; a ring-shaped insert member of heat-resistant steel which is centered in the housing is arranged radially about the turbine wheel between the turbine wheel and the housing, which forms the outer fixed turbine wheel cover and takes over the guidance of the exhaust gases both during the entry and discharge out of the turbine wheel.
