An apparatus and method are provided for a flangeless air filter configured to be mounted onto a flat surface within an air intake system of an internal combustion engine. The flangeless air filter is comprised of a cone-shaped filter medium, retained between a base and a cap, that is fabricated to remove contaminants and particulate matter from an intake airstream. The base includes a pliable seal that forms an airtight connection between the flangeless air filter and the flat surface of the air intake system. A mounting bracket and fasteners may be used to attach the base to the flat surface, compressing the seal there between. In some embodiments, the mounting bracket may be incorporated into, and made a part of the base. A cap is disposed on a top of the flangeless air filter and configured to direct the intake airstream around the cap and toward the filter medium.

A precleaner arrangement for separating a portion of entrained material from air flow air entering an engine air cleaner. The precleaner arrangement includes a precleaner housing and at least a first flexible air deflection vane with a fixed portion secured to the precleaner housing and a deflectable portion. The deflectable portion includes a curved section extending from the fixed portion and a tail section extending from the curved section. The deflectable portion is configured to deflect in response to a sufficient air flow rate change through the precleaner arrangement, in use. Some arrangements will also include a second stage, outlet vane assembly.

An intake device includes an air filter that filters intake air for an internal combustion engine, a filter casing housing the air filter, and an air physical quantity sensor. The filter casing includes an intake passage to allow the intake air to pass from upstream to downstream of the air filter. The filter casing has a passage wall portion that is electrically conductive and exposed to the intake passage on a downstream side of the air filter. The air physical quantity sensor has: a sensor element that detects a specific physical quantity related to the intake air on a downstream side of the air filter; and a grounding structure electrically connected to the passage wall portion for grounding the sensor element.

Various embodiments relate to a filter housing seal member. The filter housing seal member includes a first member end and a second member end disposed axially away from the first member end. A first member portion is disposed between the first member end and the second member end. A second member portion is disposed between the first member end and the second member end. The second member portion is disposed radially away from the first member portion. An undercut is positioned along the first member portion, the undercut configured to receive and form a seal with a filter seal member of a filter element.

Vehicle Engine Air Intake System and Method (to be accompanied by FIGS. 1 and 3) In a motor vehicle (12), an air filter housing (14) is at least partially defined by a cross-member (28) forming part of a structural front end module of the vehicle body. The cross-member (28) defines a recess (44) for receiving an air filter (90) and at least one air inlet aperture opening into the recess. An air filter enclosure assembly is mounted to the cross-member over an open face of the recess. The air filter enclosure assembly may include an air filter enclosure (42) and an air filter (90).

A control system for turbine systems configured to utilize an intelligent model of particulate presence and accumulation within turbine systems to address engine maintenance, erosion, corrosion, and parts failure mitigation is disclosed. The control system may build an intelligent model of fluid flow based on the data value measured by at least one sensor and based on a database of known data values to provide an estimation of amount of ingress of air intake particles into the turbine system, fouling within the turbine system, erosion of at least a portion of the turbine system, and performance degradation rate of the turbine system.

A filter assembly includes a support fame, a filter media, and a conditioning device. The filter media is coupled to the support frame. The filter media has a dirty side that receives an air stream and a clean side that outputs the air stream after having been filtered by the filter media. The conditioning device is coupled to the support frame. The conditioning device is positioned downstream of the clean side of the filter media with respect to the air stream and directly contacts the clean side of the filter media.

The invention relates to an air filter housing for use in an air cleaning arrangement for cleaning air to be provided to an air inlet of an internal combustion engine. The air filter housing comprises: a filter housing inlet for receiving air; and a filter housing outlet for providing filtered air to the air inlet of the internal combustion engine when an air filter is arranged inside the air filter housing between the filter housing inlet and the filter housing outlet. The air filter housing further comprises a closing arrangement controllable to be in each of a first state in which the filter housing outlet is closed by the closing arrangement, and a second state in which the filter housing outlet is open. The closing arrangement may comprise an iris shutter.

An air filter element inlcudes a first end and a second end located opposite to the first end in relation to a longitudinal direction of the air filter element. The air filter element is configured for axial insertion into a filter housing with the first end leading the axial insertion. The air filter element inlcudes a gripping structure at the second end, the gripping structure comprising an external surface accessible for interaction by a tool to facilitate removal of the air filter element from the filter housing. The gripping structure is also configured to, during insertion of the air filter element into the filter housing, radially align the air filter element in the filter housing.

The present invention relates to filter housing (12) of a filter (10) for a fluid and a filter (10). The filter housing (12) comprises a housing body (24), which is comprising at least one openable installation opening and at least one housing cover (26), which is configured to close off the at least one openable installation opening, and at least one fastening and/or locking device (186), which is configured to secure the at least one housing cover (26) in its closed position in the housing body (24). The housing body (24) comprises an element receptacle configured to receive, through the at least one openable installation opening at least one filter element. At least one fastening and/or locking device (186) has at least one U-shaped bracket element (188), whose arm sections (206) are connected to a cross beam (192), and at least one eccentric element (187) which is mounted rotatable with respect to a rotation axis (190) on the cross beam (192). The at least one bracket element (188) can pivot with respect to a bracket pivot axis (196) such, that the cross beam with the at least one eccentric element (187) is pivotable on the side of the housing body (24) with the at least one installation opening. In a closed position the at least one eccentric element (187) is engaged with the at least one housing cover (26) and the at least one bracket element (188) grips around the housing cover (26) such, that a part of the housing cover (26) is located between the arm sections (206) of the bracket element (188).
