A multi-fuel system which will operate the usual factory-manufactured gasoline powered internal combustion engine efficiently on any one of a number of different fuels without modifying or changing the engine. The system involves a non-venturi type of carburetor having a metered inlet and means for controlling the pressure of each fuel delivered to the inlet in accordance with the stoichiometric ratio of that fuel which assures that the proper fuel/air ratio is delivered to the mixing chamber of the carburetor without requiring any change in either the carburetor or engine when a different fuel is used. Additionally, the fuel delivered to the fuel inlet is then directed into the fuel/air mixing chamber without subjecting the fuel to the suction in the intake manifold of the engine.

A multi-fuel system for an internal combustion engine including, a carburetor having an air inlet and a fuel inlet and means for mixing said air and liquid fuel to form a combustible mixture which is conducted to the engine to operate the same; a first liquid fuel supply assembly having means for regulating the pressure of said first fuel which is to be supplied to the fuel inlet of said carburetor; a second liquid fuel supply assembly having means for regulating the pressure of said second fuel which is to be supplied to the fuel inlet of said carburetor; means for selectively directing either the first or second liquid fuel to the carburetor to operate the engine on such selected fuel; means in each fuel supply assembly for selectively adjusting the regulated pressure of each fuel delivered to the fuel inlet of the carburetor, said pressure being set in accordance with the fuel being used to assure that the required fuel/air ratio of the combustible mixture is supplied to the engine.
