    摘要： A filtration system includes an air cleaner housing and a filter element. The air cleaner housing includes a base and a removable cover. At least one of the base or the cover defines a cavity and a protrusion extending into the cavity. The filter element is disposed within the cavity. The filter element includes a plurality of media blocks each including a pleated filter media. The plurality of media blocks are arranged in arch shapes of approximately equal inner radii. The plurality of media blocks are coupled to each other along opposing edges that extend along a pleat direction of the pleated filter media. The media blocks together define at least one void that extends along the protrusion. The protrusion occupies a portion of the void.

    摘要： An air filter retention interface for use with an internal combustion engine is disclosed. The interface is substantially secured in an opening of a wall and the interface attaches to an air filter at the front end of the interface and an air intake tube on the back end of the interface. The interface has a filter sleeve and a filter base. During operation of the engine the filter sleeve is disposed through the opening in the wall such that the wall is between beads disposed on the external surface of the filter sleeve and the filter base thereby substantially securing the interface in place and the front end of the filter base is attached to the filter and the back end of the filter base is attached to the air intake tube and air passes through the filter then through the filter base and filter sleeve and then into the air intake tube and toward the engine.

    摘要： A hydrocarbon absorbing air filter box is provided for absorbing evaporative hydrocarbon emissions from an air intake duct of an internal combustion engine. A combined mass airflow sensor and hydrocarbon trap comprising the hydrocarbon absorbing air filter box includes a duct supporting a hydrocarbon absorbing sheet within an interior of a housing. The duct communicates an airstream from an air filter to the air intake duct during operation of the internal combustion engine. An opening in the housing receives a mass airflow sensor into the duct, such that the mass airflow sensor is disposed within the airstream. Guide vanes extending across the duct reduce air turbulence within the airstream passing by the mass airflow sensor. Ports disposed along the duct allow the evaporative hydrocarbon emissions to be drawn into the interior and arrested by the hydrocarbon absorbing sheet when the internal combustion engine is not operating.

    摘要： An evaporative emissions control system for an internal combustion engine having an air intake manifold is provided. The system includes a carbon canister configured to receive fuel vapor, a purge valve fluidly coupled to the carbon canister, an air induction system configured to fluidly couple to the air intake manifold, a conduit fluidly coupled between the purge valve and the air induction system, and an inlet valve disposed in the air induction system. The inlet valve is configured to selectively move between an open position and a closed position to vary an air restriction in the air induction system and generate a vacuum. The vacuum draws fuel vapor from the carbon canister through the conduit into the air induction system.
