Abstract
This apparatus for moisturizing the intake air going into an engine carburetor has one or more venturi passageways, each defined by a water permeable, porous body surrounded by water. The intake air is drawn into the venturi passageway where it becomes moisturized or humidified before going into the carburetor.
Claims14
A moisturizer for an engine carburetor comprising:
- an open-ended housing for connection at one open end to the air intake of the carburetor, said housing having an air inlet opening at its opposite end;
- an open-ended, annular body inside said housing defining a venturi passageway between its ends for conducting air from said air inlet opening of the housing to said air intake of the carburetor, said body having a reduced diameter throat at which air pressure in said body is at a minimum, and having tapered portions at both axial sides of said throat tapering outwardly therefrom, said body for at least a portion of its extent being spaced from said housing to define therewith a water chamber at the outside of said body, said body at said latter portion of its extent being porous to pass moisture from said water chamber for evaporation into the air flowing through said venturi passageway, said venturi passageway providing increased migration of water through said body at said throat due to the reduction of air pressure at said throat;
- and means on said housing for introducing water into said chamber.
