Abstract: A fuel filtration system configured to separate water from fuel is described. The system includes a housing having an inlet for receiving fuel to be filtered, an outlet for supplying filtered fuel to a device, and an internal compartment having a drain. A filter media is positioned within the internal compartment of the housing, the filter media configured to separate the water from the fuel, the separated water routed out of the internal compartment through the drain. A solenoid valve is configured to provide both the separated water and fuel to an exhaust after-treatment device in fluid communication with the fuel filtration system.

Abstract: A rotating coalescer having an ejected coalesced liquid separating device is described. The separating device prevents re-entrainment of liquid into a stream of filtered gas. The rotating coalescer includes a rotating filter element or coalescing cone stack positioned within a rotating coalescer housing. The outer surface of the rotating filter element or the outlet of the coalescing cone stack is displaced from the inner surface of the rotating coalescer housing. The gap between the rotating filter element or the coalescing cone stack and the rotating coalescer housing allows for ejected coalesced liquid, such as oil, to accumulate on the inner surface of the rotating coalescer housing for drainage and allows for filtered gas, such as air, to exit through a clean gas outlet of the rotating coalescer housing.

Abstract: Filter housings that have housing wall surface irregularities are described. The surface irregularities are positioned on the inner walls of the housings and/or axial ends of the housing walls. The surface irregularities may be, for example, grooves, ribs, bumps, and the like. The surface irregularities provide an engine integrity protection (EIP) feature by preventing non-approved replacement filter elements from forming seals against alternative sealing surfaces of the housing wall inner surfaces or axial ends.

Abstract: A filter that is retained in a shell housing by the use of a snap connection. The filter includes an endplate having snap features that interact with a groove in an inner portion of the shell housing. The groove may extend 360 degrees around an inner circumference of the shell housing. Accordingly, when the shell is unthreaded from the head for service (e.g., during a filter replacement service), the shell only needs to be displaced the length of the inner radial seal interface between the shell and the head, not the entire length of the filter media thereby minimizing the stroke length needed to service the filter assembly.

Abstract: A filter cartridge for use within a filter housing of a filter assembly that includes a filter media, a first endplate attached to a first end of the filter media, and a second endplate attached to a second end of the filter media. The second endplate includes a plurality of extensions extending axially away from a surface of the second endplate. The plurality of extensions possess a toothed profile and are sized and positioned so as to engage with at least one rib associated with a portion of the filter housing such that, when at least one of the plurality of extensions is engaged with the at least one rib, a rotation of the portion of the filter housing in a first direction results in a corresponding rotation of the filter cartridge.

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: Composite filter media is formed from multiple layers of media material including a nanofiber media layer, where the layers are laminated, bound, or otherwise composited to each other. The composite filter media can comprise at least one nanofiber layer comprising polymeric media material having a geometric mean fiber diameter of about 100 nm to 1 μm, and fibers configured in a gradient such that ratio of the geometric mean diameter of fibers at the upstream face of the nanofiber layer to the geometric mean diameter of fibers at the downstream face of the nanofiber layer is about 1.1 to 2.8, preferably about 1.2 to 2.4.

Abstract: The application generally relates to digital Engine Integrity Protection (EIP) systems for filters for internal combustion engines and methods of using the digital EIP systems. A pre-programmed digital chip is integrated in filtration hardware such that the Engine Control Unit (ECU) or another controller installed on the engine or vehicle can read encrypted digital signal from the chip when electrically connected with the filter hardware. Based on the read information from the chip, the ECU or controller can determine whether the filter associated with the chip is a genuine filter or a non-genuine filter.

Abstract: A rotating separator has a housing preventing separated liquid carryover. A plenum between the annular rotating separating filter element and the housing sidewall has one or more flow path separating guides minimizing the flow of separated liquid to the outlet. The flow path guides may include one or more fins and/or swirl flow dampers and/or a configured surface.
