Assembled Camshaft with Integrated Oil Mist Separation 2007-01-0260

The worldwide focus on reducing the emissions, fuel and lubricant consumption in engines is leading engineers to consider the crankcase ventilation and oil mist separation system as an important means of control. In today's passenger cars the oil mist separation systems mainly use the inertia effect (e.g. labyrinth, cyclone etc.).
In this work a new concept for oil mist separation will be presented. The concept combines the assembled camshaft with an oil mist separator. This allows for a pre-separation effect through centrifugal forces at the entry point to the rotating camshaft and an additional efficiency gain thru the swirl generator, which is integrated into the camshaft.
