ABSTRACT:
An exhaust gas driven turbocharger includes a center housing comprising a circumferentially extending annular wall enclosing a cavity in which the bearings supporting the turbocharger shaft are mounted. The center housing also includes a separate hollow annular member, which extends circumferentially around the shaft and extends radially from the circumferentially extending wall to the shaft. A cavity is defined within the hollow annular member, which receives coolant from the vehicle coolant system, to thereby control heat transfer from the turbine to the center housing and the bearings contained therewithin.
