Abstract: A separation assembly comprises a housing, a jet that expels a fluid within the housing, and a turbine positioned within the housing. The fluid causes the turbine to rotate about a center rotational axis within the housing. The turbine comprises a first axial end, a second axial end, and a plurality of vanes extending axially relative to the center rotational axis from the first axial end to the second axial end. The plurality of vanes defines axially-extending channels between each of the plurality of vanes. The first axial end comprises a radially-extending structure that axially blocks the flow of the fluid through the first axial end. The second axial end does not comprise any structure that axially blocks the flow of the fluid through the second axial end.

Abstract: Various rotating coalescer elements are described. The rotating coalescer elements include various arrangements of stacked separator discs or cones. In some arrangements, the described rotating coalescer elements include a combination of stacked separator discs or cones and filter media. In some arrangements, the stacked separator discs are designed to provide the largest possible amount of radial-projected separation surface area in a given rotating cylindrical volume, where flow to be cleaned is passing radially (outwardly or inwardly) through the rotating coalescer element. In some arrangements, this is achieved by stacking non-conical separating plates containing various area-maximizing features (e.g., spiral ribs, axial cylinders, spiral grooves, or spiral “V” shapes).

Abstract: Various embodiments relate to an air intake duct. The duct includes louvers forming an air inlet to a housing. Each louver includes an inlet section and an angled section, the angled section inclined with respect to the inlet section. The duct includes the housing positioned downstream of the louvers in an air flow direction. The housing includes a drain configured to permit separated water from an intake air passing through the louvers and into the housing to be drained from the housing. The duct includes an inner inlet duct that provides the intake air to a component. The inner inlet duct extends into the housing and positioned downstream of the louvers in the air flow direction. The inlet duct extends above the drain by a distance thereby forming a well in the housing between a top of the inner inlet duct and the drain.

Abstract: A crankcase ventilation system having a heat transfer conduit included therein. The system includes a housing and a crankcase ventilation filter element within the housing, the crankcase ventilation filter element configured to separate oil and oil aerosol from blow-by gases from a crankcase. An oil inlet is configured to receive pressurized oil from a component of an internal combustion engine. The conduit is positioned within the housing. The conduit is positioned along a length of the housing and is configured to carry the pressurized oil from the oil inlet to a component of the crankcase ventilation system. The conduit is configured to transfer thermal energy from the pressurized oil to the housing. An oil outlet is configured to return the pressurized oil to the crankcase.
