A device to meter and control the flow of a gaseous fuel and air to an internal combustion engine. The portion of the device which controls the flow of gaseous fuel comprises a reservoir chamber linked to a pressurized fuel supply, a plurality of individual chambers equal in number to the number of engine cylinders, demand valves connected to the individual chambers which permit fuel to flow on the intake stroke of each cylinder and valves biased to a closed position between each individual chamber and the reservoir for controlling the flow of gaseous fuel to the individual chambers and a connection for linking the valves to the throttle of the engine to open the valves simultaneously. The portion of the device for controlling air flow to the engine cylinders comprises an air control connected to the engine throttle and to the fuel control portion of the device to regulate entry of the air to the engine manifold and one-way air valves associated with each cylinder to allow air to enter the cylinder on the intake stroke of the cylinder.

A device for controlling the flow of a gaseous fuel to an internal combustion engine, said engine having a plurality of cylinders, and operable in conjunction with apparatus to control the flow of air to said cylinders comprising: (a) a reservoir having an inlet for receiving gaseous fuel under pressure; (b) a plurality of chambers equal in number to the number of said cylinders, each of said chambers being in individual fluid communication with said reservoir; (c) means for separately connecting each of said chambers to a respective one of said cylinders; (d) individual valve means biased to a closed position for controlling the fluid communication between said chambers and said reservoir; (e) means connected with the throttle of said engine for simultaneously opening said valve means against said bias in response to actuation of said throttle; and (f) means connectable with said air control apparatus for regulating the flow of air to said engine.
