Abstract: A filter assembly includes a drain port comprising a top portion and at least one surface modification along the top portion. The drain port defines an aperture therein and is alignable with an outlet port. The outlet port includes a seal member that is attachable to an end portion of the outlet port. A portion of the aperture of the drain port is sealable to the seal member when the drain port and the outlet port are aligned such that the at least one surface modification of the drain port does not abut the seal member of the outlet port, thereby creating a sealed connection between the drain port and the outlet port.

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: A separation assembly comprises a housing and a bearing plate assembly. The housing contains a turbine assembly and a rotor portion and defines a fluid inlet and a fluid outlet. The bearing plate assembly is adjustably attachable to the housing and defines a drive jet that directs fluid from the fluid inlet to the turbine assembly. The bearing plate assembly is mountable to the housing in multiple different orientations such that the relative position of the fluid inlet of the housing and the drive jet of the bearing plate assembly is adjustable.

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 first housing section and endcap. The filter media is structured to filter 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 filtration monitoring system is an electronic system control module installed on an internal combustion engine or within a vehicle powered by the internal combustion engine. The filtration monitoring system monitors the health and status of the filtration systems present on the engine. The filtration monitoring system tracks filter loading patterns and predicts remaining service life of the filters by running smart algorithms based on sensor feedback (e.g., pressure sensor feedback, fluid quality characteristic sensor feedback, etc.). In some arrangements, the described filtration monitoring systems provide feedback as to whether a genuine (i.e., authorized, OEM approved, etc.) or unauthorized filter cartridge is installed in a given filtration system. The filtration monitoring system may be retrofit into an existing internal combustion engine or vehicle that does not already have a filtration monitoring system.

Abstract: A fuel-water separator includes a cartridge assembly and a bowl. The cartridge assembly receives a fuel-water mixture and provides a fuel. The cartridge assembly includes an endplate. The bowl is configured to store water separated from the fuel-water mixture. The bowl is coupled to the endplate. The endplate includes an air vent that receives air from the bowl. The air vent establishes a pressure equilibrium within the bowl and the cartridge assembly.

Abstract: A separator system comprises a main separator, and an additional separator including one of a pre-separator, post separator, or line-of-sight baffle. The additional separator separates liquid particles from an air/liquid mixture and comprises an inlet, an air outlet, a liquid outlet, and a plurality of posts disposed between the inlet and the air outlet. The posts are arranged in a staggered array and comprise a convex end portion having an impaction surface, a portion of liquid particles from the air/liquid mixture adhering as a liquid film to the impaction surface, and a hook end portion positioned downstream the convex end portion and including hooks having an end and a collection pocket disposed between the impaction surface and the end. The collection pocket collects the portion of liquid particles adhered as the liquid film to the impaction surface.

Abstract: A method comprises providing a polymer. The polymer is heated to a first predetermined temperature so as to liquefy the polymer. The liquefied polymer is formed into a polymer fiber. The polymer fiber is cross-linked to form a cross-linked polymer fiber comprising a polymer network by at least one of cooling the polymer fiber to a second predetermined temperature lower than the first predetermined temperature or exposing the polymer fiber to a cross-linking stimulus, the cross-linked polymer fiber capable of being decross-linked by heating to a third predetermined temperature above a characteristic decross-linking temperature of the polymer.

Abstract: An anti-counterfeiting mechanism for a filter element to specifically, and preferably uniquely, identify a filter with a conductive pattern or path of conductive materials preferably either embedded (thin film circuit) under the surface, or over molded on, a portion of the filter. The conductive materials are preferably positioned at the filter end cap. The resistance of the filter element is an identifier that is preferably associated with the OEM manufacturer's labeling (such as product number) and/or other branding of the component. This electrical resistance signature permits rapid identification of counterfeit filters.
