A fuel conditioning device (1) for attachment to a fuel line (5)
of a fuel combustion machine to improve combustion efficiency thereof. The device
(1) includes a frequency controlled signal generator (14) powered
by a power supply (2). The frequency controlled signal generator (14)
has a first output being connected to the 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. The frequency controlled
signal generator (14) has a second output connected to the 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 waveform voltage signal (16) is an inverted mirror
signal of the first shark dorsal waveform voltage signal (15).
