ABSTRACT:
A portion of the air filter means ahead of an engine carburetor is provided as a porous water absorbent foam material and means is also provided to supply water or a water-alcohol mixture to the lower portion of the foam such that it will be wetted and impart moisture to the air stream passing through the air filter unit. A preferred unit automatically supplies fluid to the lower face of the foam material to maintain wetness and an open-cell foam material is also used which will effect a wick-like, capillary action to insure a wet porous surface for the air stream flow.
