Abstract:
A turbocharger for an internal combustion engine includes a bearing housing and a bearing bore defined by the bearing housing. The bearing bore has an annular bearing groove configured to receive a fluid. A journal bearing is disposed within the bore such that the annular bearing groove encircles the journal bearing and feeds the fluid thereto. The turbocharger also includes a rotating assembly having a shaft with 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 annular bearing groove is characterized by a trapezoidal shape in a cross-sectional view of the bearing bore taken along and through the longitudinal axis. The trapezoidal shape is configured to generate Taylor vortices in the fluid for capturing debris carried by the fluid and keeping the debris from being fed to the journal bearing.
