A no filter no run (NFNR) fluid filter and fluid filter assembly are provided. The NFNR fluid filter assembly includes a fluid filter, a filter head or filter housing, and a bypass flow path. The bypass flow path may be sealed off when a compliant filter is installed. When a non-compliant filter is installed (a filter without a bypass seal), fluid may flow to the bypass flow path.

No filter no run fluid filter with integration of low pressure fluid system

A filter assembly includes a conditioning device that conditions a flow of air upstream of a mass air flow sensor. The filter assembly includes a support frame. The filter assembly further includes a filter media coupled to the support frame, the filter media having a dirty side configured to receive a stream of air and a clean side configured to output a stream of air that has been filtered through the filter media. The filter assembly includes a conditioning device coupled to the support frame, the conditioning device positioned in a downstream direction from the clean side of the filter media with respect to the stream of air, the conditioning device offset from the clean side of the filter media by a separation distance.

System and method for improving mass air flow signal quality

An electronic system providing unique identification of a genuine filter system assembly to the engine control unit ('ECU'). A resistor is made to be an integrated part of the filtration system hardware such that when connected through a wired connection, the ECU detects a particular voltage signal and identifies the system as a genuine filter. The resistor could be integrated in any part of the filter system such that it could be used to recognize the filter or the cartridge. The resistor connection could be made via male/female pins, conducting wires, plates, conductive plastic material or other mechanisms.

Electronic filter detection feature for liquid filtration systems

A filter apparatus is described that has a torque limiting device, which may be a clutch mechanism, and which provides a protective function for a filter, so as to protect a filter from being over tightened and to thereby prevent damage to filter components. The clutch mechanism can also eliminate or reduce the need for torque measurement of certain filter components. The clutch mechanism can be located on one of the fluid filter, a filter head which engages the fluid filter, or a combination of both the fluid filter and the filter head.

Filter apparatus with torque limiting mechanism

A no filter no run (NFNR) fluid filter and fluid filter assembly are provided. The NFNR fluid filter assembly includes a fluid filter, a filter head or filter housing, and a bypass flow path. The by-pass flow path may be sealed off when a compliant filter is installed (a filter without a bypass seal), fluid may flow to the bypass flow path.

An internal combustion engine crankcase ventilation rotating coalescer includes an annual rotating coalescing filter element, an inlet port supplying blow by gas from the crankcase to the hollow interior of the annular rotating coalescing filter element, and an outlet port delivering clean separated, air from the exterior of the rotating element. The direction of flow by gas inside-out, radially, outwardly from the hollow interior to the exterior.

An internal combustion engine crankcase ventilation rotating coalescer includes an annular rotating coalescing filter element, an inlet port supplying blowby gas from the crankcase to the hollow interior of the annular rotating coalescing filter element, and an outlet port delivering cleaned separated air from the exterior of the rotating element. The direction of blowby gas is inside-out, radially outwardly from the hollow interior to the exterior.

A filter assembly, including an air cleaner assembly for an internal combustion engine in an underhood engine compartment, includes a mounting bracket with a flow passage therethrough. In one form, a combination air filter element and base is provided for an air cleaner assembly. In a further form, a filter assembly includes a filter element integrally and permanently mounted to the base for removal and replacement as a single unit.

Filter assembly with mounting

A disposable, spin-on fluid filter for mounting to a fluid-directing head includes a molded housing having a closed base and a sidewall defining a hollow cavity. Filtering media is positioned within the hollow cavity and a nutplate is joined to the housing so as to enclose the filtering media. The nutplate includes a plurality of inlet flow openings and a lobed sleeve extending into the filtering media. An endplate is joined to the filtering media including a flange portion and a sleeve portion. The fluid filter includes an elastomeric valve having a first portion positioned between the flange portion and the inlet flow openings and a second portion positioned between the sleeve portion and the lobed sleeve. The valve provides an anti-drain back capability and in cooperation with the lobed sleeve provides a filtering media by-pass capability.

Spin-on filter with performance enhancement features

A fluid filter constructed and arranged for threaded engagement with a fluid-delivery head for the filtration of an incoming fluid includes a molded plastic shell having a sidewall formed with a retaining ridge, a closed end and an opened end surrounded by a series of external threads, a fluid filter media pack installed into the fluid filter shell, the media pack including filtering media and an upper endplate bonded to the upper end of the filtering media, wherein the upper endplate includes a peripheral lip that is constructed and arranged to snap into position axially beneath the retaining ridge. The threaded engagement between the fluid filter shell and the fluid-delivery head eliminates the need for any nutplate.

Open-end flow entrance spin-on filter

An electrostatic precipitator includes an inertial gas-contaminant impactor separator providing two stage separation and reducing contaminant collection load on the collector electrode at the corona discharge zone to reduce contaminant build-up thereon and extend service intervals for cleaning or replacement thereof.
