Filter media and media packs that provide robust performance in high-speed rotating coalescer (HSRC) elements for crankcase ventilation systems are described. The fiber media is HSRC fiber media. As such, the filter media has a higher resistance to compressibility then traditional coalescer filter media, such as fiber media used in low-speed rotating coalescer arrangements or stationary coalescer arrangements.

High speed rotating crankcase ventilation filter media and media pack

Filter media and media packs that provide robust performance in high-speed rotating coalescer (HSRC) elements for crankcase ventilation systems are described. The filter media is HSRC filter media. As such, the filter media has a higher resistance to compressibility than traditional coalescer filter media, such as filter media used in low-speed rotating coalescer arrangements or stationary coalescer arrangements.

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.

Rotating separator with housing preventing separated liquid carryover

Disclosed are multiple stage rotating coalescer devices comprising a first stage and a second stage. The first stage may include a rotating coalescing element comprising coalescing media. The second stage is positioned either upstream or downstream or the first stage. The second stage may include one of: (i) a rotating cone stack separator, or (ii) a separate rotating coalescing element comprising coalescing media.

Multiple stage rotating coalescer devices

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.

Crankcase ventilation inside-out flow rotating coalescer

A filter element is described that includes an endplate that also serves as the lid or cover for the filter housing. The combined endplate/lid includes a central hole that is closed to fluid flow when the proper filter element-housing combination is used. Various embodiments for different functional uses of the central hole are also described.

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.

An engine air management system is provided for an internal combustion engine generating blowby gas in a crankcase containing engine oil and oil aerosol. The system includes combinations of two or more of an air-oil separator, an air filter, and an acoustic silencer.

Engine air management system

A pleated filter element extends axially between an upstream inlet and a downstream outlet along a plurality of axially extending bend lines forming axial flow channels. The bend lines taper in a transverse direction and define a plurality of axially elongated tetrahedron channels facing oppositely to each other.

Method and apparatus are provided for making a filter element by spinning fibers from one or more dies onto a collector, including designated combinations providing designated filter characteristics.

Method and apparatus for making filter element, including multi-characteristic filter element

A crankcase ventilation system for an internal combustion engine includes a separator and an amplifier increasing at least one of flow and pressure along the flow path through the separator to provide higher separation efficiency.
