  • Filter Precleaner
    Publication number: 20180264387
    Abstract: A filter precleaner for precleaning an unfiltered gaseous mixture. A coalescing filter includes a filter media for filtering a gas, a nozzle assembly for precleaning an unfiltered gaseous mixture, and a lower endplate. The nozzle assembly includes a first nozzle plate positioned upstream of the filter media. The lower endplate is positioned at a lower end of the filter media beneath the first nozzle plate. The lower endplate allows liquid to drain through the lower endplate. The unfiltered gaseous mixture impacts the lower endplate such that liquid from the unfiltered gaseous mixture flows through the lower endplate and gas from the unfiltered gaseous mixture flows through the filter media.

  • Rotating Coalescing Element with Directed Liquid Drainage and Gas Outlet
    Publication number: 20180243677
    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.

  • Air Filter Arrangement
    Publication number: 20180229170
    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.

  • IDENTIFYING VISCOSITY GRADE AND NEW OIL STATUS BASED ON DIELECTRIC AND VISCOSITY SENSOR
    Publication number: 20180231518
    Abstract: A lubrication system for an internal combustion engine and a method of monitoring the lubrication system are described. The lubrication system generally circulates lubricant from a sump (i.e., a reservoir), through a filtration system, to the internal combustion engine, and back to the sump. The lubrication system includes a controller that monitors a dielectric constant of the lubricant and a viscosity of the lubricant. Based on the dielectric constant, the controller can determine whether the lubricant flowing through the lubrication system is new lubricant (e.g., recently replaced lubricant) or old lubricant (e.g., lubricant that has degraded enough to be distinguished from new lubricant). If old lubricant is identified, the viscosity of the lubricant is compared against threshold viscosities to dynamically determine when the lubricant requires replacement.

  • AIR-OIL SEPARATOR WITH JET-ENHANCED IMPACTION AND METHOD ASSOCIATED THEREWITH
    Publication number: 20180230873
    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.

  • Fuel water separator filter
    Patent number: 10047708
    Abstract: A fuel water separator filter is described that is configured as a filter-in-filter construction with multiple water separating layers to separate water from the fuel. The fuel water separator filter is configured for use on a suction side of a fuel pump, and includes a neck with a radially outward facing seal that in use seals with the filter housing. The filter housing is formed with an isolated water sump that in use is isolated from water that is stripped from the fuel by the first stage of the outer filter. The isolated water sump is formed by a wall within the housing, instead of relying on an outer diameter seal on the filter to form the water sump.

  • Snap in place natural gas filter
    Patent number: 10046263
    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.

  • APPARATUSES, SYSTEMS AND METHODS FOR PROVIDING FILTER RECOGNITION
    Publication number: 20180214801
    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.

  • NO FILTER NO RUN FEATURE FOR FILTER
    Publication number: 20180214803
    Abstract: A filter cartridge is provided that is designed to actuate a valve that controls fluid flow into an outlet for discharging filtered fluid. The valve receives a ball at a first position which is axially movable between the first position and a second position. If a filter cartridge is not installed or an inappropriately designed filter cartridge is installed, the ball is moved from the first position to the second position to seal an outlet opening of the outlet. If the described filter cartridge is installed, the ball is retained at the first position by a holding member and the valve allows filtered fluid flow into the outlet opening.

  • Installation of correct filter cartridge in fluid filter assembly before allowing assembly to be completed
    Patent number: 10016711
    Abstract: The descriptions relate to preventing assembly of a fluid filter apparatus unless a filter cartridge is installed, and preventing assembly of a fluid filter apparatus if the incorrect filter cartridge is installed. A mechanism includes cooperation of a movable member and a structure that can move the movable member to ensure that a fluid filter apparatus cannot be completely assembled, for example connecting its filter head to its shell, when there is no cartridge installed inside the shell or when there is an attempt to install an incorrect cartridge. This can protect from an inadvertent or intentional failure to install a cartridge (or correct cartridge) in the fluid filter apparatus.
