Abstract
A positive crankcase ventilation (PCV) system is provided for an internal combustion engine. The PCV system includes a centrifugal separator disposed within a shaft member, for example a balance shaft, of the internal combustion engine. The centrifugal separator is operable to impart rotational motion on the gases flowing through the shaft member such that the centrifugal forces urge the separation of oil particle entrained within the gases.
