In a saddle-ride type vehicle in which an air cleaner is arranged inward in a vehicle width direction of at least a pair of left and right main frames and arranged below a riding seat, a cleaner case for the air cleaner is configured long in a longitudinal direction of the vehicle and has a cleaner case main portion storing therein a cleaner element, and a connecting tube connection portion extending forward from the cleaner case main portion so as to be connected to a connecting tube. A pair of left and right side covers covering the cleaner case from opposite sides in the vehicle width direction are supported by side cover supporting portions that are provided on left and right opposite side walls of the cleaner case main portion and the connecting tube connection portion.

An air cleaner includes a filter element, a case having an opening and being configured to accommodate the filter element, and a lid configured to close the opening. The case includes a wall including a first surface and a second surface that are formed on at least one of an outer surface and an inner surface of the case and are continuous with each other in an opening direction of the opening through intermediation of a stepped portion. The case further includes a rib formed on at least one of the first surface and the second surface to extend in the opening direction.

A vehicle includes an air cleaner box assembly disposed within an engine compartment. The air cleaner box assembly includes a moveable shell portion and a stationary shell portion. The moveable shell portion includes an upper surface disposed adjacent a hood, and defines a filtered air chamber. The stationary shell portion is attached to a structure, and defines an unfiltered air chamber. A filter element is attached to and supported by the moveable shell portion. The filter element separates the filtered air chamber and the un-filtered air chamber. Each of a plurality of spring loaded guide members slideably connect the moveable shell portion and the stationary shell portion, and guide the moveable shell portion along a path relative to the stationary shell portion, between an expanded position and a compressed position.

In a saddle-ride type vehicle in which a cleaner case of an air cleaner is configured with first and second case half bodies coupled to each other and arranged in a vehicle width direction, and is arranged in a space surrounded by a vehicle body frame, a first case half body is provided with: a cleaner element insertion/removal port opened outward so as to permit insertion and removal of a cleaner element therethrough; a purified air outlet connected with a connecting tube for guiding purified air to an engine body side; and an outside air suction port for introducing air from an outside into the cleaner case.

A work vehicle includes a hood, an engine, a radiator, an air cleaner, and a condenser. The hood covers an engine compartment located on a front portion of a traveling body. The engine is a drive source. The radiator supplies a coolant to the engine. The air cleaner takes in outside air and supplies the air to the engine. The condenser cools a refrigerant. In front of the radiator, the air cleaner and the condenser are disposed one above the other. The condenser is withdrawable in the left and right direction.

An apparatus and a method are provided for an aircharger air intake system for filtering and conducting an airstream to an air intake of an engine. The aircharger air intake system includes an air filter comprising a filter medium configured to entrap particulates flowing within the airstream. An air box comprising one or more sidewalls and a mount wall is configured to support the air filter within an engine bay. The air box is configured to be mounted, or fastened, onto the engine. An intake tube is coupled with the air filter and configured to conduct the airstream to the air intake of the engine. The intake tube is configured to be coupled with an air temperature sensor or a mass air sensor of the engine. An adapter is configured to couple the intake tube with the air intake.

An apparatus and method for a heat shield with an integrated air filter assembly is disclosed. Wherein the air filter assembly comprising a filter material circumferentially extending such that the filter material surrounds at least a portion of an interior cavity of the air filter, a distal end cap affixed to a distal end of the filter material, and a wire support extending along at least a portion of an exterior surface of the filter material; and wherein the heat shield is configured to direct cooler air into an air intake conduit extending from an intake portion of an automobile engine for combustion.

An apparatus and a method are provided for a multiple inlet air box to communicate an airstream through an air filter to an air intake duct of an internal combustion engine of a vehicle. The multiple inlet air box is comprised of a housing that supports the air filter within an interior of the housing. A mount portion within the housing fixedly receives a base of the air filter. Multiple air inlets couple with corresponding air inlet ports of the vehicle to direct the airstream into the multiple inlet air box. A duct directs the airstream from the multiple air inlets to the interior of the housing. A conduit communicates the airstream from an interior of the air filter to the air intake duct of the internal combustion engine.

The present invention belongs to the technical sector of fluid filtration systems which can be used for air filtration in an internal combustion engine.

The invention refers to a filtering device (1) including a filtering element (24) which presents an open axial end (26) and an axial end (27) closed by a cover (28); and an intake cover (7). The said cover (28) includes at least a first tubular boss (55) projecting towards the intake cover (7); and the intake cover (7) includes at least a second tubular boss (57) complementary to the first tubular boss (55) and projecting towards the cover (28); the first tubular boss (55) is slotted in the second tubular boss (57).

The invention also refers to a tubular filtering element (24) and to a maintenance process of a filtering device.

An air-cleaner structure of a saddle-ride vehicle is provided with an air-cleaner case arranged between a seat and a head pipe located in front of the seat. The air-cleaner case is provided with a bottom half and a top half. The bottom half is arranged in a space surrounded by a rear face of the head pipe and a pair of left and right main frames extending from the head pipe toward the rear of the vehicle. The top half is situated above the main frames. The top half is provided in a vertical two division structure. A dividing surface of the vertical two division structure of the top half is inclined in the vehicle-longitudinal direction. An air-cleaner element is mounted along the inclined dividing surface.
