Abstract: Various arrangements of a turbine for a rotating coalescer element of a crankcase ventilation system for an internal combustion engine are described. In some arrangements, the turbine is an impulse turbine, which is also known as a pelton turbine or a turgo turbine. The turbine is used to convert hydraulic power from a stream of pressurized fluid to mechanical power that is used to drive the rotating element. The turbine includes a non-wetting surface (e.g., an oleophobic or hydrophobic surface) that repels the pressurized fluid. The non-wetting surface may be achieved through plasma coating, fluoropolymer coating, micro-topography features, and the like. The non-wetting surface increases the power transmission efficiency from the stream of pressurized fluid to the turbine, thereby increasing the rotational speed of the rotating element compared to wettable surfaced turbines, which in turn increases the efficiency of the rotating element.

Abstract: A filter element for filtering a fluid that comprises a pleated filter media and a support structure. The pleated filter media comprises pleats that define an upstream gap along an upstream surface of the pleated filter media and a downstream gap along a downstream surface of the pleated filter media. The support structure extends along the downstream surface of the pleated filter media and supports the pleats. The support structure is folded into two layers comprising a first layer and a second layer within the downstream gap. The first layer inner surface and the second layer inner surface are positioned adjacent to each other within the downstream gap. The support structure comprises at least one spacer that increases a distance between the first layer outer surface and the second layer outer surface such that the differential pressure drop through portion of the support structure that is within the downstream gap is decreased.

Abstract: A filter cartridge having a bypass filtration media is described. The filter cartridge includes main filtration media. In some arrangements, the main filtration media includes first filtration media and second filtration media that has a different filtering efficiency than the first filtration media. The filter cartridge is configured to be installed in a filtration system having a bypass mode. While in the bypass mode, fluid passing through the filtration system is allowed to bypass the main filtration media. To avoid unfiltered fluid from passing from the inlet of filtration system to the outlet (e.g., and on to an internal combustion engine), the fluid flows through the bypass filtration media (e.g., during cold start conditions). In some arrangements, the bypass filtration media has a lower filtering efficiency than the main filtration media.

Abstract: A rotating separator includes a filter housing extending axially along a longitudinal axis and a filter element positioned within the filter housing. The filter element includes a first endplate and a second endplate operatively coupled to the first endplate, a first element core and a second element core positioned between the first endplate and the second endplate and configured to filter a contaminate from a fluid. An interior cavity is defined between the first endplate, the second endplate, the first element core, and the second element core. Fluid flowing through the filter element enters the interior cavity and is split between and flows in parallel through the first element core and the second element core.

Abstract: Filtration systems having a tangential air cleaner having a coiled media filter element and a cyclonic pre-cleaner are described. An outer wall of the filter element acts as a pre-cleaner sleeve of the housing to generate a cyclonic flow of the intake air prior to the intake air being filtered by the filter element. The housing cover includes geometry that redirects the cyclonic low from a tangential path to an axial, straight-through flow directed through an inlet flow face of the filter element. Various embodiments of such filtration systems offer increased filter performance and capacity compared to similarly sized cylindrical pleated filter elements having a radial flow filtering path.

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.
