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 flow 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: 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: Rotating coalescer crankcase ventilation (CV) systems are described. The described CV systems utilize a contact seal to seal a gap between a static side of a housing and a rotating coalescer inlet. The rotating coalescer may be driven mechanically, electrically, hydraulically, or the like. The contact seal can be formed via a soft solid or a liquid film created by oil. Accordingly, the contact seal is a hydrodynamic soft seal. The contact seal prevents the blowby gases from bypassing the filter element of the rotating coalescer. At the same time, the contact seal may be broken during positive blowby gas recirculation circumstances because the contact seal is a hydrodynamic soft seal.

Abstract: A filter assembly comprises a filter head, a port, a fitting, and a diffuser. The port extends from a portion of the filter head and defines a channel for fluid to flow into or out of the filter head. The fitting first end is attachable to the port and the fitting second end is attachable to a filtration system component. The diffuser is positionable within the channel of the port and comprises an inner surface and an outer surface. The inner surface defines an inner conical hollow region that extends at a nonzero angle between the inner conical hollow region first end and the inner conical hollow region second end such that a first inner diameter of the diffuser at the inner conical hollow region first end is smaller than a second inner diameter of the diffuser at the inner conical hollow region second 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: A system and method for determining a condition of a filter filtering fuel associated with an engine. Input information relating to the operation of the engine is provided by a plurality of sensors. At least some of the input information is used to determine a plurality of input variables, the plurality of input variables representing a plurality of engine operating conditions including engine run time, engine torque and engine speed. An algorithm incorporating the input variables is used to determine the condition of the filter. Information concerning the condition of the filter may be output to a user such as an operator or service provider.

Abstract: The combination of a gas-pressure-driven pump jet nozzle or alternatively Coanda effect nozzle with an impactor nozzle(s) in an air-oil separator for separating oil from blow-by gasses from a crankcase of an internal combustion engine, or for separating liquid aerosol from gas, in general. Such combination enhances impaction efficiency and enables operation at higher pressure differentials (or pressure drop) (“dP”) without causing excessive backpressure in the air-oil separator.

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.
