Abstract
Official abstract text for this publication.
A turbocharger for an internal combustion engine includes a shaft, a first turbine wheel, a compressor wheel, and a second turbine wheel. The shaft includes a first end and a second end and is supported for rotation about an axis. The first turbine wheel is mounted on the shaft proximate to the first end and configured to be rotated about the axis by post-combustion gasses emitted by the engine. The compressor wheel is mounted on the shaft between the first and second ends and configured to pressurize an airflow being received from the ambient for delivery to the engine. The second turbine wheel is mounted on the shaft proximate to the second end and configured to be rotated about the axis by a pressurized fluid. An internal combustion engine employing such a turbocharger is also disclosed.
First claim
Opening claim text (preview).
The invention claimed is: 1. A turbocharger for an internal combustion engine having an oil pump configured to supply a pressurized engine oil, the turbocharger comprising: a shaft having a first end and a second end, the shaft being supported for rotation about an axis by at least one bearing; a first turbine wheel mounted on the shaft proximate to the first end and configured to be rotated about the axis by post-combustion gasses emitted by the engine; a compressor wheel mou…
