Abstract: Inertial particle separators having an axially translating or a deformable poppet component are described. The poppet component axially translates to accommodate a wide range of flowrates through the inertial particle separator. In some arrangements, the poppet component is biased by a spring towards a closed or restricted position. The variable flowrate and constriction provided by the poppet maintains a substantially constant pressure drop and separation efficiency during operation across a wide range of flowrates through the separators.

Abstract: Various example embodiments relate to rotating coalescers. One embodiment includes a housing comprising a first housing section having a blowby gas inlet structured to receive crankcase blowby gases from a crankcase. The housing further comprises an oil outlet. The rotating coalescer includes an endcap and filter media. The filter media is arranged in a cylindrical shape and is coupled to and positioned between the crankcase blowby gases passing through the filter media by coalescing and separating oils and aerosols contained in the crankcase blowby gases. The rotating coalescer includes a hollow shaft extending through the housing and positioned radially inside of the filter media. The hollow shaft forms a blowby gas outlet structured to route filtered crankcase blowby gases out of the housing. The rotating coalescer further includes a drive mechanism operatively coupled to the hollow shaft.

Abstract: A Spin-on filter assembly that can be used with both suction-side and pressure-side filtration systems is described. The filter assembly screws onto a filter mounting head. The filter mounting head is part of a filtration system that provides fluid to be filtered to the filter assembly. The filter assembly filters the fluid to be filtered through a filter media contained within the filter assembly and provides the filtered fluid back to the filter mounting head. The filter assembly includes an upper seal that seals the clean side of the filter media from the dirty side of the filter media when the filter assembly is connected to the filter mounting head in an installed position. The upper seal includes a sealing ridge that has an elongated shape and is flexible such that the filter assembly can be used on both pressure-side and suction side applications in filtration systems.

Abstract: A fuel filter assembly for filtering a fuel-liquid mixture comprises a filter cartridge and a return tube. The filter cartridge comprises a filter media and a housing. The filter media defines an open central region therein. The housing contains the filter media. The return tube extends into the central region of the filter media. The return tube collects and drains liquid from a bottom inner region of the filter media.

Abstract: A filter monitoring system and method are described. The filter monitoring system includes a module or circuit installed on an internal combustion engine or within a vehicle powered by the internal combustion engine. The filter monitoring system monitors the operation of the various filtration systems present on the engine to determine an amount of service life remaining and a loading percentage for various filter cartridges installed in the filtration systems of the internal combustion engine. The filter monitoring system determines the loading percentage and predicts remaining service life of a given filter cartridge via a time-based manner (e.g., based on the installation date of the filter cartridge and filter cartridge life specifications) and a pressure differential based manner (e.g., based on a determination of pressure drop across the filter cartridge).

Abstract: An attachment and retaining mechanism is described for removably attaching a rotating filter element to a rotating shaft. The rotating filter element includes a filter media that is driven by a drive mechanism that rotates the rotating shaft. The filter element is removably attached to the rotating shaft such that the filter element and filtration system can be periodically replaced and/or serviced. In some arrangements, the drive shaft includes a D-shaped section that interacts with a mating section of the filter element sleeve of the rotating filter element. In other arrangements, the drive shaft includes at least one flat drive surface.

Abstract: A filter element for fuel, oil or other engine fluids, with an endplate that is designed to create flow paths for both clean and dirty regions. The filter element is part of a spin-on filter that is attachable to a filter head in an engine and that filters fuel, oil or other engine fluids. A pre-fill cap can be integrally incorporated onto the endplate to permit pre-filling and installation without removing components.

Abstract: Filtration systems having a normal filtration mode and an enhanced filtration mode are described. In some arrangements, the filtration system is an air filtration system having a primary air filter element, a pre-cleaner, and a pre-cleaner bypass valve. Based on feedback from an intake air quality sensor the bypass valve is either opened or closed to selectively route intake air through the pre-cleaner during sensed dirty air operating conditions (e.g., heavy dust or moisture concentrations). In other arrangements, the filtration system is a liquid filtration system (e.g., a fuel or oil filtration system) that has a main filter and a secondary filter. The filtration system selectively routes the liquid being filtered through the main filter, the secondary filter, or a combination thereof depending on a detected event or sensed characteristic of the liquid.

Abstract: A no filter no run bidirectional pin element is disclosed. A shell housing is removably coupled to a filtration housing, a removable no filter no run attachment, and a filter element. The filter element comprises a filtration media and a bidirectional pin element. The bidirectional pin element comprises a center tube formed as a single piece with a bidirectional pin. The installation of the filter element and the shell housing into the filtration system results in the bidirectional pin entering a pin aperture of the removable no filter no run attachment and the bidirectional pin preventing the operative engagement of a blocking element with a divider inside the no filter no run attachment.

Abstract: Systems and methods for determining whether an authorized or genuine filter element is installed in a filtration system are described. The authorized filter determination may be based on radio frequency identification (“RFID”) technology. RFID readers with antennas in the monitored filter systems read the RFID tag information from the installed filter elements and feed any detected information into the filter monitoring system. The filter monitoring system or a remote diagnostic system analyzes the returned data (or absence thereof) to determine if a genuine (i.e., authorized, OEM approved, etc.) filter element is installed or not.
