An ultrasonic transducer is provided substantially at the hot spot in an engine manifold for vaporizing the fuel from the carburetor prior to entry of the fuel-air mixture into the cylinders. Transducer comprises a crystal adapted to be vibrated at a high frequency on the order of at least 1,000,000 Hz and a resonator tuned to the frequency of the crystal and operatively secured to the crystal, said transducer having an active surface adapted to be contacted by the fuel for finely vaporizing same. The fine vaporization or gasification of the fuel (gasoline, for example) prior to entry into the cylinders causes a more complete burning of the fuel. As a result, the engine delivers more power with less fuel, while carbon monoxide and hydrocarbon emissions are reduced. In operation, the ultrasonic transducer enhances cold weather startup and operation, eliminates engine flooding, smooths out engine idle, and improves pick up and acceleration by increasing power at low engine RPM. Engine power is boosted, while saving gasoline. The ultrasonic transducer can be installed into the intake manifold below the carburetor without modifying the structure of the carburetor or the intake manifold.
