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. The 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.

For use in an internal combustion engine having a carburetion means connected to an engine intake manifold, the improvement comprising an ultrasonic transducer for vaporizing the fuel disposed substantially at the hot spot in the engine intake manifold, said transducer comprising 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 connected to the crystal, said resonator having an active surface adapted to be contacted by the fuel for finely vaporizing same for better mixture with the air from the carburetion means, whereby the internal combustion engine will deliver more power, while reducing carbon monoxide and hydrocarbon emissions, and saving fuel, and mounting means for supporting the ultrasonic transducer inside the engine intake manifold between an opening thereto through which the fuel/air mixture passes from the carburetion means and the hot spot of the engine intake manifold without any alteration of the engine intake manifold or engine specifications.
