Abstract
A breather system for a crankcase of an internal combustion engine, includes a centrifuge driven by the engine turbocharger. The turbocharger has a turbine and a compressor, the compressor driven by the turbine. The centrifuge is driven by the turbine on a common shaft with the compressor and includes a centrifuge inlet, a gas outlet and an oil outlet. Crankcase gas is delivered to the centrifuge and oil is removed by the centrifuge and collected within the turbocharger housing and substantially oil free gas is passed through the centrifuge, through an axially passage in the shaft and into an inlet of the compressor.
