<p>An ultrasonic device (6) for a liquid fuel introduction system that propagates ultrasonic waves (36) through liquid fuel (20), improving the combustion efficiency of the liquid fuel (20). The propagated waves (36) cause a reduction or unification of fuel droplet size by breaking apart larger fuel droplets into a distribution of uniform sized fuel droplets, thereby producing a smoother combustion wavefront in an internal combustion engine. The end result is greater fuel efficiency of the I.C.E. The ultrasonic wave (36) is produced via at least one piezoelectric transducer (26) having first and second electrodes (28, 29) adapted to receive an input signal of predetermined frequency and voltage which produces vibrations within a piezoelectric element (26) for generating ultrasonic waves, respectively. The frequency of the ultrasonic wave is varied and tailored so that the most efficient frequency is matched to the specification of a particular fuel (e.g., gasoline, diesel, etc.).</p> |
