Abstract: An apparatus is provided for controlling the flow of crankcase emissions. The apparatus includes a crankcase emissions regulator for regulating the flow of crankcase emissions discharged from an engine crankcase, a pressure sensor for sensing a crankcase pressure, and an electronic control module (ECM) for controlling the emissions regulator. The ECM adjusts the emissions regulator in response to the pressure differential between the detected crankcase pressure and a predetermined pressure value programmed in the ECM.

Abstract: Apparatus for receiving crankcase emissions from an internal combustion engine and for separating the liquid portions of the emissions from the gaseous portion thereof. The apparatus includes a mounting flange, an opening for the return of the liquids to the engine, and at least one layer of filtering material. In one embodiment, the filtering material may be soaked with oil. Another embodiment has a screw mounted in the housing, and positioned to retard the flow of emissions exiting from the housing. The apparatus includes an outlet for return of the gaseous portion of the emissions to return to the combustion chamber via the PCV line or the induction manifold.
