Abstract:
A turbocharger for an internal combustion engine includes a center housing and a bore defined by the center housing. The bore has a primary annular groove and a secondary annular groove configured to receive a fluid. A journal bearing is disposed within the bore proximate to a proximate end of the shaft such that the journal bearing, together with the rotating shaft, feeds fluid to the primary and secondary annular grooves. The shaft is further coupled to a turbine wheel and a compressor wheel. The shaft has a longitudinal axis and is supported by the journal bearing for rotation within the bore about the axis. The primary and secondary annular grooves are each in fluid communication with a drain gallery.
