An air cleaner for a combustion engine including air and fuel induction passages is provided and the air cleaner defines an inner chamber downstream from an associated air filter element. The inner chamber opens into the air and fuel induction passages of the engine and a reservoir for an evaporative liquid is provided, including an upper portion defining a filtered air inlet and a vapor outlet. An elongated conduit extends between and communicates the vapor outlet with the inner chamber within the air cleaner and a liquid absorbent and porous body is provided within the chamber for floating on the liquid therein, the body when in use defining increased wetted surface area from which liquid contained within the reservoir may be evaporated by air entering the reservoir through the air inlet and being drawn from the reservoir through the vapor outlet.

In combination with a combustion engine including an air cleaner defining an inner chamber downstream from an associated air filter element and which opens into the air inlet of a carburetor mounted on and operable to supply a mixture of air and fuel to the air and fuel induction passages of said engine, a reservoir for containing an evaporative liquid, an upper portion of said reservoir including a filtered air inlet and a vapor outlet, and an elongated vapor conduit extending between and communicating said vapor outlet and inner chamber, a liquid absorbent porous body disposed within said reservoir for free vertical movement therein and comprising a buoyant body which may be floated on various liquids contained within said reservoir including water, alcohol and lighter engine fuels, such as gasoline and methonal, said air cleaner being of the conventional type defining an upwardly opening horizontal annulus for receiving an annular air cleaning element in the outer peripheral portion thereof and equipped with a disk-shaped cover, said elongated conduit including an outlet end fitting threaded downwardly through a portion of said cover inward of the outer peripheral portion of said annulus.
