Abstract
An air filter comprising, in addition to a porous paper annular filter, a filter in the form of a canopy disposed above the air outlet orifice. This filter comprises a trellis forming a support for absorbent material meshes extending into a water tank. The meshes become wet by absorbing the water from the tank by capilliary action and ensure, by forced convection, a humidification of the air aspirated by the engine.
Claims3
A device for filtering and humidifying the intake air of an internal combustion engine, comprising a casing including a top wall, bottom wall and side wall, an air inlet conduit in said side wall, an air outlet orifice in said bottom wall, a first filter in said casing in the flow path of intake air between said inlet conduit and said outlet orifice, a second filter comprising a plurality of absorbent material elements, a water tank attached to the outside of the bottom wall of said casing, conduit means connecting said tank to the interior of said casing, a portion of said second filter absorbent material elements disposed in said casing in the flow path of exit air, another portion of said absorbent material elements passing through said conduit means to said water tank and submersed therein to absorb water by capillary action and thereby humidify the air aspirated by said internal combustion engine.
