Abstract
A dual fuel system is disclosed which, when retrofitted to a standard gasoline engine of an automobile, permits the automobile to run on one of two fuels. The dual fuel system comprises two fuel tanks; two carburetors, each connected to a fuel tank and powered by a separate fuel pump; a venturi housing communicating with the carburetors and forming two venturi throats, each throat in registry with an outlet of a carburetor; an adapter forming a single passage therethrough and including an end adapted to be mounted on an intake manifold such that the passage is in registry with an intake opening in the intake manifold; a valve, located in between the venturi housing and the adapter means, for alternately opening and closing a pathway from a preselected venturi throat to the single passage of the adapter so that only one venturi throat communicates with the single passage at a time; a single throttle linkage connected to the throttles of the carburetors such that the throttles of the carburetors operate in unison; a valve linkage which allows remote control of the valve; and a slave linkage extending between the valve linkage and a distributor which is driven by the valve linkage and…
