Vaporous gasoline fuel system and control therefor

A fuel system for use with an internal combustion engine having associated fuel delivery means and fuel ignitable means for power conversion comprising, a containable source for liquid ignitable fuel, a collector means communicating with said source for collecting fuel fumes or vapor adapted to emanate from said liquid ignitable fuel, means communicable with atmosphere and extending into the container source being operable to transmit air into said source above the liquid fuel therein for generating a fumed fuel-air mixture therefrom, means for transmitting the fumed fuel-air mixture from said collector means to the associated fuel delivery means of the engine for ignition therein, means coacting with the means communicable with atmosphere and responsive to actuation of the engine for insertion of liquid ignitable fuel into said communicable means for intermixing with intake air therein, means coacting with said communicable means for diffusing the fuel-air mixture entering into said containable source above the liquid fuel therein, and electronic control means coacting with said engine and said fuel system being responsive to the operating load conditions of said engine to correspondingly control the fuel to air ratio of the mixture prior to the transmission of said mixture to said fuel delivery means of said engine effective to maintain said mixture at its optimum combustible composition.
