Abstract: The charge for an internal combustion engine is comprised of a mixture of heated fuel-vapor-laden air and ambient air drawn through an air filter in a conventional manner. The vapor-laden air is obtained by first heating air in a heat exchanger (15) to a given temperature by picking up heat from the engine's exhaust. The heated air is then drawn through a fuel-saturated air permeable element (21). Fuel is delivered to the air permeable element (21) and continuously circulated thereover. As the heated air passes through the element (21) it becomes laden with fuel-vapor; and, is cooled to a second temperature that is substantially below the first. The cooled fuel-vapor-laden air is then mixed with additional air and the resulting charge is delivered to the engine's intake manifold.

Abstract: Carburetors for attaching to fuel-burning engines are described. The carburetors generate improved engine efficiency and reduced engine emissions by improving combustion of fuel. The carburetors include a plurality of nebulizers, each of which nebulizes a thin film of fuel covering a vibrating plate. The vibrating plate vibrates at a high frequency, and this vibration ejects a fog or mist of fuel particles into an air/fuel mixture channel that passes above the nebulizers in series. Air is drawn into the air/fuel mixture channel, passes over each of the plurality of nebulizers in turn, and then passes to a nebulized fuel outlet within a Venturi narrowing of a main channel of the carburetors. The Venturi narrowing provides a reduced air pressure area that performs the function of drawing the air through the air/fuel mixture channel over the nebulizers, thus drawing out the mixed air and nebulized fuel.

Abstract: A fuel system especially designed for use with an internal combustion engine (10) or the like, which fuel system is operable therewith to provide fuel fumes or vapor to the engine (10) from a source of liquid ignitable vaporizable fuel. The fuel system includes an air supply conduit (36, 36', 36'', 36''') to which fuel (50, 57, 57'', 57''', 57a) can be added by a separate fuel supply line (50, 50', 100) at its upstream end and whose downstream end is connected to a container of liquid fuel (16, 16', 16''). The air, with the additional fuel, can then be treated by a swirling device (44, 44', 44''') prior to its admission to the container of fuel or supplied directly to the container where it interacts with the fuel, directly, or indirectly through a wick device (77'', 77''', 77a), produces a vapor, and exits through a collector (24, 24'), connected to a fuel supply conduit to the engine.
