Abstract: The present invention relates to a system for delivering an air-fuel mixture to an internal combustion engine in a virtually complete gaseous form. The system is essentially comprised of a converter which dries intake air and combines the dried air with gas vapor and an air modulator for adding additional atmospheric air to the air-gas vapor mixture. The convertor contains an activated charcoal substance which enhance evaporation of the fuel, prevents "gumming" of the fuel in the convertor, and inhibits condensation of the fuel after evaporation. The air-gas vapor mixture is then fed to an internal combustion engine. In a first embodiment, the system may be installed as an add-on apparatus to an automotive engine which already uses fuel injection as fuel feeding means. In that embodiment, disabling means are installed to disable the fuel injectors. In a second embodiment, the system may be utilized as original equipment for feeding an air-fuel vapor mixture to an internal combustion engine.

Abstract: A system for providing an air-fuel vapor mixture to an engine for improving completeness of combustion and also reducing emissions. The system includes a vaporizer within which a series of baffles are disposed such that air and fuel pass along a tortuous passageway defined within the vaporizer. Exhaust gases provide heat to the vaporizer, and as air and fuel pass along the passageway of the vaporizer, a homogenous air-fuel vapor mixture is produced, with the homogenous mixture exiting the vaporizer being supplied to the engine by way of an adapter plate assembly. When used with a carburetor, the adapter plate is disposed between the carburetor and the engine.

Abstract: Liquid gasoline introduced from a suitable source into a treatment tank of the system is transformed into a relatively dry vaporous state substantially free from large droplets or similar particles. Pellets within an outer chamber of the vessel are propelled by air streams into engagement with each other, and with walls of the vessel, and generate frictional heat. Baffle members in an inner chamber of the vessel reduce the size of droplets of gasoline in such chamber. Dry gas is conducted from the treatment vessel to a holding tank, from whence it is supplied to the intake manifold of the engine. Valves of the system are operated in response to actuation of an accelerator associated with the engine. Liquid gasoline from a lower portion of the vessel is supplied to the intake manifold of the engine during initial start-up, and at other times when no dry gasoline vapor is present within the holding tank.

Both forms of the invention include supplemental vaporized fuel supply devices operable during acceleration and starting.

Abstract: A novel method and improved apparatus are disclosed for generating fuel vapor from a volatile normally liquid fuel, safely handling and controlling the fuel vapor, and utilizing the same in the operation of an internal combustion engine. Preferably, the fuel vapor is generated by introducing the liquid fuel under pressure into the lower portion of a vessel via an elongated tubular member having a plurality of spaced openings. The pressurized liquid fuel flows from the openings under vigorous conditions of agitation and fuel vapor is evolved from the liquid surface without forming finely subdivided liquid droplets in the vapor phase. Air is mixed with fuel vapor in the upper portion of the vessel in an amount sufficient to lower the dew point, but insufficient to produce an explosive mixture. The mixture is withdrawn from the vessel and, after adding sufficient air to produce an explosive mixture and for efficient combustion, is passed to the intake manifold.

Abstract: Hot water is transmitted from an automobile's cooling system to a fuel vaporizer wherein it is utilized to heat gasoline to a vapor state. Air is drawn into the fuel vaporizer utilizing carburetor vacuum and is added to the vapor and drawn into the carburetor. Vaporized fuel and outside air are mixed in a separate dry vapor section within the vaporizer and the amount of air allowed to enter the fuel vaporizer is controlled utilizing a valve system. In this manner, the fuel-air vapor is more efficiently burned in the engine and improved gas mileage is achieved.

Abstract: A vaporizer chamber includes a coil therein, the coil having extensions extending into the exhaust pipe of the engine, the exhaust gases passing through the coil and heating the interior of the chamber. Fuel is delivered to the vaporizer chamber, and vaporized there when the exhaust gases are heated. A thermostat unit is mounted on the exhaust pipe, and when heated, shifts a valve to direct the fuel to the vaporizer chamber, instead of to the carburetor. This shifting is gradual. A throttle controls the flow of vaporized fuel to the outlet of the carburetor. The usual accelerator pedal is operative for controlling the throttle for the vaporized fuel in unison with the usual throttle provided in the carburetor.

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: A fuel vaporizer carburetor provides a continuous mixture of vaporized fuel and combustion air for operation of an internal combustion engine to meet the requirements of a wide range of engine operating conditions. Fuel vapor and combustion air undergo turbulent intermixing in an elongated mixing chamber. The mixing chamber is enclosed by a tubular wick of fiber mesh material which is saturated with fuel vapors and fuel condensate. The fuel vapors are generated by heating fuel in a float bowl which underlies the wick. Combustion air is admitted through a plurality of angularly spaced openings and is conducted through the porous flow passage provided by the tubular wick prior to entry into the mixing chamber. This arrangement produces a cyclonic, whirling movement which promotes intermixing of the combustion air and fuel vapors. Turbulence is induced at an intermediate point in the mixing chamber by a tapered sidewall housing section.

The amount of the tubing receiving air under pressure is varied in accordance with fuel demand. The fuel vapor is mixed with ambient air and directed into the intake manifold. The system includes a storage tank for providing the air under pressure, and a pump to supply air to the storage tank.
