Abstract: A disposable, spin-on fluid filter is constructed and arranged to mount onto a base that is configured with a threaded mounting shaft. The base provides a fluid inlet flow to the filter and a fluid exit path from the filter. The filter construction includes a housing canister having a closed end and an opposite, open end and a fluid filtering media positioned within the housing canister. A mounting post is formed as part of the closed first end of the housing canister. The mounting post is constructed and arranged for assembly to the threaded mounting shaft of the base. The design focuses on the elimination of any nutplate and on repositioning the location where the fluid filter is connected to the head to the closed end of the canister.

Abstract: The invention concerns the designing and production of filtering assemblies used for filtering liquids circulating in engines or hydraulic equipment. The invention is characterized in that a cylindrical element designed to support a filtering cartridge in a filtering assembly for liquid circulating in an engine or a hydraulic equipment, the cartridge including a filtering medium delimited by two plates, comprises at least two longitudinal ribs wherefrom extend a series of sloping pins.

Abstract: A filter includes a filter element formed of filter media, and a plastic framework molded and bonded to and structurally supporting the filter media. One embodiment desirably provides a two-component assembly consisting solely of two components, namely the filter media and the plastic framework molded thereon. In a further embodiment, the plastic framework includes a resilient seal integrally molded therewith and of the same plastic material thereof, eliminating a separate component for the seal. In a further embodiment, a filter combination includes a primary filter element and a secondary filter element. In a further embodiment, a resilient integrally molded seal is provided.

Abstract: An apparatus, system, and method for measuring static pressure in a warm gas flow while minimizing particulate deposit formation includes a housing containing the flow of gas, a pressure sensor, and a heated pressure sampling tube attached to the sensor, with the tube sampling the gas flow. The heated sampling tube reduces the temperature gradient between the gas and the tube, reducing thermophoretic forces that contribute to deposit formation. The sampling tube extends through the housing into the gas flow in one embodiment, enabling the gas to heat the tube and locating the open end of the tube in a higher-flow area of the gas, further reducing deposit formation.

Abstract: An oil mist removal device, with oil fill, is provided for an internal combustion engine. A housing has first and second passages, and a separator therebetween. An oil fill port in the first passage is provided for adding oil to the engine.

Abstract: An exhaust aftertreatment filter has a pre-stressed layer bonded to the filter body at the outer periphery and compressively axially pre-stressed in an opposite axial direction to separational axial tensile stress to counteract the latter during regenerative heating, to minimize separational fracture and cracking.

Abstract: A centrifuge for the separation of particulate matter from a volume of fluid includes an outer housing, a rotational member extending through the outer housing, and a rotor assembled onto the rotational member for rotation relative to the rotational member and relative to the housing. The centrifuge is constructed and arranged to enable self-driven rotation by the exit flow of fluid through jet nozzle openings defined by the rotor. The rotational member includes a fluid passageway and an exit opening for delivering fluid to the rotor. The rotor includes a divider plate that separates the interior of the rotor into a collection chamber and a separate jet zone. The collection chamber has a single fluid entry location defined by the divider plate for processing a single batch of fluid at a time.

Abstract: An air filtration cartridge has annular filter media having a hollow interior and extending axially between first and second distally opposite end caps. The first end cap is an outlet end cap having flow straightening structure integrally formed therewith and spanning the hollow interior. The second end cap is a closed end cap having an interior face having quarter wave resonators formed by blind holes therein.

Abstract: The invention provides a NOx adsorber aftertreatment system for internal combustion engines which utilizes a plasma fuel converter operatively coupled to at least one NOx adsorber to aid in the regeneration of the NOx adsorber. Fuel and engine exhaust is injected into a plasma fuel converter upstream of a NOx absorber producing reductant such as H2, and CO, which are inlet into the NOx absorber. Reductants such as H2 and CO acting along and together help to efficiently regenerate the NOx Adsorber which in turn releases exhausts products such as CO2 and N2. Using the reductants generated by the plasma fuel converter NOx adsorbers, catalytic soot filter, and the like can be regenerated at exhaust temperatures less than 250° C. The plasma fuel converter, NOx adsorber regenerating aftertreatment system of the present invention may be used with any suitable control system.

Abstract: A vertical exhaust water trap assembly has an outer housing and an internal housing or exhaust tube defining an annular water collection spaced therebetween bypassing a central exhaust flow area.

Abstract: An apparatus, system, and method are disclosed for intermittently delivering fluid. An injector intermittently delivers a first quantity of fluid over a first time interval. In one embodiment, the injector is passively cooled. In a certain embodiment, the injector delivers the first quantity of fluid responsive to a fluid flow measurement of a flow meter. An orifice diverts the first quantity of fluid from a primary fluid supply system over a second time interval without decreasing the supply of fluid to a primary load within a flow rate range while the fluid pressure remains within a pressure range. An accumulator accumulates at the least the first quantity of fluid as a fluid charge with positive energy.

Abstract: An exhaust aftertreatment device has a turbulator provided by a tube having a perforated star-plugged downstream end.

Abstract: A direct flow filter includes a pleated filter element filtering fluid flowing axially therethrough parallel to the wall segment pleat tip bend lines. Embossments on the wall segments have a height extending along a lateral direction into a respective flow channel to maintain channel width and guiding and directing fluid axially into and along the flow channels from the upstream ends of the wall segments.

Abstract: A filter has multiple pleated filter elements having axially extending channels having a transverse pleat channel height and a lateral channel width. The pleated filter elements have different channel heights.

Abstract: A lobed exhaust diffuser apparatus, system, and method configured to cool exhaust gases from an internal combustion engine comprises a diffuser having a proximal end, configured to receive exhaust gases from the engine, and a distal end, configured to expel the exhaust gases into the atmosphere. A plurality of lobes are disposed on the distal end such that at least a portion of the exhaust gases pass through the lobes, increasing the interaction surface area between the exhaust gases and the atmosphere, allowing for more rapid diffusion and entrainment between exhaust gases and atmospheric gases, resulting in more rapid cooling of the exhaust gases.

Abstract: A filter includes a filter element mounted to a base and having first and second end caps spaced axially along an axis. Fluid to be filtered flows laterally through the filter element and axially through a hollow interior and through an axial flow opening of the second end cap. The filter element is mounted to the base solely by the second end cap in rotational relationship independently of the first end cap, eliminating the third component traditionally needed for mounting a housing cover to the base and enclosing and/or sealing and/or retaining the filter element in the housing.
