A device for mounting on the inlet manifold of an internal combustion engine for carbureting liquid fuel. A chamber is provided for receiving the liquid fuel. An ultrasonic generator is positioned in the chamber and is in direct communcation with the liquid fuel in the chamber. The ultrasonic generator acts to ultrasonically vaporize the fuel in the chamber, preferably by an electronic control system. The receiving chamber is interconnected to a gasified fuel storage chamber which acts to store a quantity of vaporized liquid fuel. The storage chamber and the receiving chamber are interconnected for passing vaporized liquid fuel from the receiving chamber to the storage chamber. A monitoring device is provided, preferably an optical density detector, for determining the quantity, as well as the density, of the vaporized fuel in the vaporized fuel storage chamber and a control system responsive to the monitoring device, is provided for controlling the amount of ultrasonic energy used for vaporizing the amount of fuel required for use in the internal combustion engine, as determined by the engine load demand. An air collector is provided for communicating air with the vaporized fuel and also with the receiving chamber for the liquid fuel. A chamber and control valve are provided for regulating the quantity of the vaporized fuel-air mixture to be passed to the engine for combustion. A conduit is provided for communicating the air-fuel mixture with the inlet manifold for passing the amount of air-fuel mixture called for by the engine.
