Abstract
A method and system is provided for regenerating and cleaning an air-oil coalescer of a crankcase ventilation system of an internal combustion engine generating blowby gas in a crankcase. The coalescer coalesces oil from the blowby gas. The method and system includes regenerating and cleaning the coalescer by intermittent rotation thereof.
