Abstract: The invention relates to a filter element for mounting in an air cleaner housing of a vehicle. The filter element comprises a circumferential filtering wall through which air is allowed to enter. The filter element also comprises a first end and an open second end for fluidly connecting the filter element to a turbo. The open second end is located opposite the first end. The circumferential filtering wall extends from the first end towards the open second end. The filter element further comprises a resonator. The entire resonator is encircled by the circumferential filtering wall such that air entering through the circumferential filtering wall passes on the outside of the resonator to and through the open second end.

Abstract: A filter element for a filter system for filtering a fluid has a filter bellows arranged about a longitudinal axis and enclosing an interior of the filter element. A closed end disk is arranged at a first end of the filter element and closes off the interior of the filter element. An end disk with an opening to the interior of the filter element is arranged at a second end of the filter element oppositely positioned to the first end viewed in direction of the longitudinal axis. The closed end disk has a hollow pin projecting into the interior of the filter element in direction of the longitudinal axis. The filter system has a housing for receiving the exchangeable filter element with a housing part closable by a cover. The hollow pin of the closed end disk can be pushed onto a pin of the housing part.

Abstract: A spin tube assembly for an engine air cleaner is provided. The spin tube assembly includes a housing, a spin tube panel, a plurality of spin tubes and at least one constrictor. The plurality of spin tubes are supported on the spin tube panel in parallel relation to one another. Each spin tube of the plurality of spin tubes includes a helical element causing air entering the spin tube to rotate such that particles within the air are moved by centrifugal action outwardly against a wall of the spin tube. At least one spin tube of the plurality of spin tubes has a constrictor upstream from the helical element thereof. The constrictor causes a localized restriction of air entering the at least one spin tube compared to the spin tubes without constrictors. Methods of use and configuration are also provided.

Abstract: A secondary filter element for a filter arrangement is provided with a filter medium and a circumferentially extending sealing device that seals the secondary filter element in respect to a filter receptacle of the filter arrangement. The circumferentially extending sealing device has an oval geometry with a long side and a short side. The circumferentially extending sealing device has an outer surface projecting, in a radial direction of the secondary filter element, farther past the filter medium when viewed along the short side compared to when viewed along the long side. A filter arrangement has a filter receptacle. A main filter element is received in the filter receptacle, and a secondary filter element is received in the main filter element. The circumferentially extending sealing device of the secondary filter element projects in a radial direction of the secondary filter element outwardly past an interior of the main filter element.

Abstract: A filter assembly includes a housing, a cover, and a filter element. The housing defines a pocket. The cover includes a bayonet sized to be received within the pocket. The bayonet defines an elongated opening. The filter element is sized to be received within the housing. The filter element includes a media pack and a filter shell coupled to the media pack. The filter shell includes a trunnion that is sized to be received within both the pocket and the elongated opening to interlock the cover and the filter element such that removal of the cover from the housing initiates removal of the filter element.

Abstract: In an air cleaner (32), three cyclone dust collection units (34) are arranged on one side of a filter dust collection unit (35) in a mutually parallel relationship. The cyclone dust collection units are arranged along a circumferential direction of the filter dust collection unit, and the central cyclone dust collection unit has a smaller diameter than the remaining cyclone dust collection units positioned on either side of the central cyclone dust collection unit so that the dust collection units can be accommodated in a rectangular profile is a highly space efficient manner.

Abstract: A saddle-ridden vehicle includes: an engine and an air cleaner case that are supported to a body frame and respectively arranged in front and rear sides of the vehicle; a rear cushion arranged between the engine and the air cleaner case, the rear cushion being coupled to the body frame; and a connecting tube that extends forward from the air cleaner case and is coupled to the engine. The connecting tube upwardly bypasses an upper end of the rear cushion so as to be curvedly arranged under an occupant seat. The connecting tube defines a breather-gas return chamber between an inner wall and an upper-side outer wall of the connecting tube, the breather-gas return chamber being communicated with an internal space of the air cleaner case and receiving breather gas from the engine, the inner wall being integrated with the upper-side outer wall.
