Abstract:
A parallel vapor/liquid fuel system for use with an internal combustion engine for providing fuel to said engine as a vapor and/or as a liquid based on engine demands, comprising:a fuel source which exists in a liquid state at normal atmospheric pressure and temperature; fuel delivery means constructed and arranged to deliver fuel from said fuel source to a means for supplying liquid fuel and to a means for supplying vaporized fuel, said means for fuel delivery in fluid communication with said fuel source; a means for supplying liquid fuel to said engine, said means for supplying liquid fuel in fluid communication with said fuel source; a means for supplying vaporized fuel to said engine, said means for supplying vaporized fuel in fluid communication with said fuel source, said means for supplying vaporized fuel to said engine including at least one canister, said at least one canister having an internal vaporizing chamber, an exhaust gas inlet and a fuel vapor outlet; at least one heating means for supplying heat to said vaporizing chamber, said heating means being removably attached to said canister, said heating means being in electrical communication and operatively controlled with a fuel vaporization control means; at least one sensor for monitoring temperature within said vaporizing chamber, said sensor being removably attached to said canister, said sensor being in electrical communication with said fuel vaporization control means; at least one fuel modulating means for controlling liquid fuel admitted into said vaporizing chamber, said fuel modulating means constructed and arranged for removable attachment to said canister, said fuel modulating means in electrical communication and operatively controlled by said fuel vaporization control means; an on-board computer for monitoring vapor/liquid fuel requirements as a function of engine demand, said on-board computer in operational control of said means for supplying vapor/liquid fuel; and fuel vaporization control means in electrical communication with said computer for controlling supply of vaporized fuel.
