Abstract: Disclosed herein is an improved fuel evaporation apparatus which comprises a two-stage evaporator designed to receive fuel such as gasoline in a liquid form and to completely transform the liquid fuel into its vapor state so as to increase the efficiency of operation of the associated internal combustion engine. In the first stage, the liquid fuel is conducted so as to strike a heated plate and thereafter any fuel which still resides in the liquid state flows through holes provided in the plate in droplet form and then enters vapor tubes which conduct the fuel in heat exchange relationship with exhaust gas from the internal combustion engine. After the fuel has been completely changed to vapor by flowing the fuel through the apparatus, the fuel is conducted, preferably, to the venturi stack or stacks of the carburetor of the associated internal combustion engine. Also disclosed herein is the method of evaporating fuel utilizing the above-described apparatus.

Abstract: This device relates to a novel system for supplying fuel to an internal combustion engine. The system includes a two-stage evaporator serially mounted within the fuel supply system of the internal combustion engine. The evaporator includes a first stage having fuel supply orifices to inject fuel at the top of a chamber in which are mounted a pair of spaced thermal discs having numerous holes therethrough. The evaporated fuel is then conducted to the second stage of the evaporator where it is further expanded in a spiral tube heated by, for example, exhaust gases and then conducted to a venturi stack via a vapor control regulator valve and fuel supply manifold to the intake manifold of the internal combustion engine. Use of the system results in increased gas mileage as the high degree of vaporization of the fuel results in a much greater efficiency in the burning thereof.
