Patent ID: 6971376

Claim:
An electronic fuel conditioning device ( 1 ) for attachment to a fuel line ( 5 ) of a fuel combustion machine to improve combustion efficiency thereof, the device comprising: a frequency controlled signal generator ( 14 ) powered by a power supply ( 2 ), the frequency controlled signal generator ( 14 ) having a first output being connected to a first output wire ( 8 ) coiled around the fuel line ( 5 ) for producing a first shark dorsal waveform voltage signal ( 15 ) oscillating at a predetermined frequency, and a second output being connected to a second output wire ( 9 ) coiled around the fuel line ( 5 ) for producing a second shark dorsal waveform voltage signal ( 16 ) oscillating at the predetermined frequency, the second shark dorsal voltage signal ( 16 ) being an inverted mirror signal of the first shark dorsal waveform voltage signal ( 15 ); wherein the frequency controlled signal generator ( 14 ) includes: a main oscillator circuit ( 22 ) for producing a shark dorsal waveform oscillating at the predetermined frequency; a bi-polar-amplifier ( 24 ) coupled to the main oscillator circuit ( 22 ) to produce the first and second shark dorsal waveform voltage signals ( 15 , 16 ); and a voltage doubler circuit ( 20 ) for powering the bi-polar amplifier circuit ( 24 ) with a positive d.c. voltage (Vcc) and a negative d.c. voltage (Vss).
