<p>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.</p> |
