Abstract A fuel conservation device for internal combustion engines of vehicles, or the like, comprising a housing interposed between the usual fuel pump and carburetor of the engine, the housing having two compartments, a heating element disposed in one of the compartments, the other of said compartments having an inlet in communication with the fuel pump for receiving raw fuel therefrom and an outlet for discharging vaporized fuel therefrom, a level control device disposed in the second mentioned compartment for controlling the fluid level therein, a secondary carburetor interposed between the housing and the carburetor of the engine and in communication with the outlet of the housing and the throat of the usual carburetor for directing the vaporized fuel into the carburetor for passage therethrough to the engine combustion chamber, the heating element providing heat for the second compartment for vaporization of the fuel therein whereby substantially completely vaporized fuel is delivered to the combustion chamber to increase the fuel efficiency and reduce exhaust pollutants.
A fuel conservation apparatus for an internal combustion engine having an electrical system and a fuel pump and a carburetor, said fuel conservation apparatus comprising housing means interposed between the fuel pump and carburetor and having two independent compartments, one of said compartments being a vaporization compartment and the other of said compartments being a heating compartment, said housing having inlet port means providing communication between the vaporization compartment and the fuel pump for selectively directing said raw fuel into the vaporization compartment and outlet port means in communication with the vaporization compartment for discharging vaporized fuel therefrom, electrical heating means provided in said heating compartment and operably connected with the electrical system of the internal combustion engine for hearing the fuel in the vaporization compartment to provide vaporization of the fuel, auxiliary carburetor means interposed between the outlet port means and the carburetor whereby vaporized fuel only may be delivered to power the internal combustion engine, and bypass means connected between the fuel pump and the first mentioned carburetor for selectively bypassing the housing means and auxiliary carburetor means, a first lock off valve means interposed between the inlet port and the fuel pump for providing selective flow of fuel to the housing, and second lock off valve means interposed between the housing and the carburetor for cooperation with the first lock off valve means to remove the fuel conservation apparatus from the internal combustion engine system if desired.
