Abstract
A turbocharger for an internal combustion engine includes a bearing housing with a bearing bore and a semi-floating bearing disposed within the bore. The turbocharger also includes a shaft having a first end and a second end, wherein the shaft is supported by the bearing for rotation about an axis within the bore. The turbocharger also includes a turbine wheel fixed to the shaft proximate to the first end and configured to be rotated about the axis by post-combustion gasses emitted by the engine. Additionally, the turbocharger includes a compressor wheel fixed to the shaft proximate to the second end and configured to pressurize an airflow being received from the ambient for delivery to the engine. Furthermore, the turbocharger includes a plate secured within the bearing housing and configured to prevent rotation of the bearing about the axis. An internal combustion engine employing such a turbocharger is also disclosed.
