Abstract
Abstract A fuel system especially designed for use with an internal combustion engine or the like in which fuel system is operable therewith to provide fuel fumes or vapor to the engine from a source of liquid ignitable vaporizable fuel, such as gasoline, of sufficient quantity whereby to significantly increase the efficiency of the engine and thus substantially increase the per gallon mileage rate for the engine when used in an automotive vehicle or the like, and one using liquid fuel as the original fuel source. The system includes improved means for fuming the liquid fuel.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
171 words
A fume tank adapted for use in providing vaporous fuel to fuel delivery means of a gasoline powered engine, said tank comprising an enclosure adapted to receive in the bottom thereof a pool of liquid fuel, means for transmitting fluid including atmospheric air into said enclosure from exteriorly thereof, means coacting with said transmitting means for insertion of liquid ignitable fuel into said transmitting means responsive to the actuation of said engine, means for removing vaporous fuel from said enclosure for transmittal to associated fuel delivery means of the engine, means disposed above the liquid pool and coacting with and mounted on the lower end near the outlet of the transmitting means for dispersing fuel-air mixture from said admitting means into said enclosure in a swirling-like effect, and other means coacting with and mounted on the opposite end of the transmitting means for reversing the direction of the swirling-like effect to the fuel air mixture in said enclosure prior to its being supplied to the means for removing the vaporous fuel.
Claim 2
Dependent Claim
171 words
A fume tank adapted for use in providing vaporous fuel to fuel delivery means of a gasoline powered engine, said tank comprising an enclosure adapted to receive in the bottom thereof a pool of liquid fuel, means for transmitting fluid including atmospheric air into said enclosure from exteriorly thereof, means coacting with said transmitting means for insertion of liquid ignitable fuel into said transmitting means responsive to the actuation of said engine, means for removing vaporous fuel from said enclosure for transmittal to associated fuel delivery means of the engine, means disposed above the liquid pool and coacting with and mounted on the lower end near the outlet of the transmitting means for dispersing fuel-air mixture from said admitting means into said enclosure in a swirling-like effect, and other means coacting with and mounted on the opposite end of the transmitting means for reversing the direction of the swirling-like effect to the fuel air mixture in said enclosure prior to its being supplied to the means for removing the vaporous fuel.
Claim 3
Dependent Claim
75 words
A fume tank in accordance with claim 1 wherein said coacting means comprises a pair of spaced dispersing members including upper and lower plates and intermediate curved vanes, the vanes in one of said members being curved in one direction to cause the swirl-like effect in one rotary direction, while the vanes of the other of said dispersing members are curved in the opposite direction to cause the swirl-like effect in the opposite rotary direction.
Claim 4
Dependent Claim
37 words
A fume tank in accordance with claim 2 including means in said enclosure for maintaining a pool of liquid fuel, and means for removing liquid fuel from said pool and supplying it to the first mentioned means.
Claim 5
Dependent Claim
22 words
A fume tank in accordance with claim 2 including control means for maintaining a predetermined level of liquid fuel in said enclosure.
