Abstract
An air filtration system for an internal combustion engine is provided wherein the air filter has an exit orifice for sealingly engaging the air intake duct of a carburetor via a friction-fit. The friction-fit provides an integrated seal between the orifice and duct such that additional sealing means are not required. The friction-fit can be provided by a plurality of ridges formed along the interior surface of the orifice or by decreasing the cross-sectional area of the orifice in the direction of the internal cavity formed by the filter walls. Decreasing the cross-sectional area of the orifice is accomplished by providing a plurality of stepped diameters of a bottom surface material or a surface that conically slopes inward towards the cavity. In addition, the air filter can be secured to a platform of an engine by a holding arm having a hook shaped distal end with a catch that can be disengaged by pulling at a grip, thus allowing easy access to the filter for inspection, cleaning, and replacement.
