Abstract: A fuel vaporizing device for use with internal combustion engines including a carburetor, an air filter, and a fuel tank. In the device of the present invention fuel consumed by the engine is directed to source such as a fuel tank to a conventional carburetor with the fuel aspirated and mixed with engine air and burned in a conventional manner. Fuel in the second fuel conduit is directed to a fuel vaporizer where the fuel is heated to enhance vaporization. An air pump directs air to the fuel vaporizer where the air collects vapor, and the air and vapor are directed to the carburetor upstream of the carburetor throttle valve where the air and vapor are mixed with the air passing through the carburetor.

Abstract: In a vehicle comprising a liquid-cooled gasoline fueled internal combustion engine a supplemental adapter apparatus comprising tanks, valves and conduits is incorporated into the cooling system and fuel system of that internal combustion engine with some modification of the fuel feeding and the cooling systems of that engine and continually utilizes the normally unused heat of the liquid coolant of such engine to fractionate liquid fuel mixtures fed to that engine with continual intermittent use of resulting separate fractions thereby formed to improve the efficiency of conversion of the potential energy of such liquid fuel to mechanical energy.

Abstract: A method and means for reducing fuel consumption in an internal combustion engine, or the like, and which comprises nebulization of fuel for injection into the usual automobile carburetor. The normal fuel nozzle of the carburetor is closed or removed and the nebulization system of the vapor tower is utilized to replace the function of the nozzle to provide a more efficient fuel utilization. The apparatus provides its own vacuum, and may be readily utilized with a turbo charge system, or the like, as well as the usual or normal carburation system.

Abstract: A gasoline fume generator and mixer for use with an internal combustion engine is disclosed. Liquid fuel is fed through a metering valve and flows over a hot heat exchange unit which is maintained at a temperature above 200.degree. F. by flow of engine coolant therethrough. The fumes generated by contact of the fuel with the heat exchange unit are mixed with air which is pulled into the generator tank by vacuum. This fume and air mixture is pulled out of the tank and into the carburetor to operate the engine in a conventional manner. A liquid level float actuated flow control device and a flap valve are provided to control the operation of the generator and a clean out plug is provided to allow periodic removal of portions of the liquid fuel which are not turned into fumes by the generator. An optional electric resistance heater is used to elevate the temperature of the liquid fuel entering the generator and mixer when needed, such as in cold weather and quick starts.

Abstract: In vaporization means for liquid fuel for an internal combustion engine, the mixture strength is measured and used to control the rate of flow of liquid fuel into the air stream so as to maintain the mixture strength constant. Measurement of mixture strength is effected by measuring the temperature drop in the air flow due to the latent heat of the liquid fuel.

Abstract: Hot water is transmitted from an automobile's cooling system to a fuel vaporizer wherein it is used to heat gasoline to a vapor state. Air is added to the vapor by a fan, then forced to the carburetor. The flow of vapor into the carburetor is controlled by adjusting a vapor pickup within the carburetor's air cleaner. In this manner, the fuel-air vapor is more efficiently burned in the engine and better mileage is achieved.

Abstract: A modified internal combustion engine useful as a power plant in automotive vehicles is operated on an admixture of air and fuel vapor. An apparatus is disclosed for generating the fuel vapor from a volatile normally liquid fuel of the type useful in operating a conventional internal combustion engine having a prior art carburetor. Apparatus is also disclosed for safely handling and controlling the fuel vapor thus generated, and utilizing the same in the operation of the internal combustion engine. In a further aspect, a novel method is provided for generating vapor of a volatile liquid fuel and operating an internal combustion engine therewith. The method is also useful in modifying a conventional internal combustion engine including a prior art carburetor. The resultant modified internal combustion engine operates more efficiently and with lower exhaust emissions.

Abstract: Charge forming apparatus of the fluid jet type in which the tubular supply member is acutely angled with respect to the housing passageway and the slot therein is located closely adjacent to the passageway wall and to a location of initial opening of the pivoted butterfly valve in the passageway which controls the air flow across the slot and through the passageway.

Abstract: Disclosed is a fuel vaporizer system for forming a mixture of vaporized fuel and air and injecting the mixture into the intake manifold of a spark ignition internal combustion engine. The vaporizer unit includes a canister containing a controlled liquid level of fuel and a foraminous body partially submerged in the liquid fuel to promote rapid vaporization of the fuel. The canister contains a dividing wall above the foraminous body so that air drawn into the canister must pass through the foraminous body and mix with the vaporized fuel. The vaporization unit functionally parallels the conventional carburetor and includes means to control the flow of gas through the vaporizer and control the pressure in the intake manifold.

Abstract: A fuel delivery system for an internal combustion engine, including a vaporizing chamber for combining liquid fuel and air to produce a vaporized fuel and air mixture, a vapor expander which communicates with the chamber for expanding and further vaporizing the mixture, and a metering device which communicates with the expander and with the engine for supplying engine vacuum to the system and controlling the amount of the mixture which is supplied to the engine.
