Abstract: A catalytic fuel conditioner has an insulated conveyance (1) for containing fuel-conditioning catalytic material with either of a selection of liquid-contact structures (7, 11, 12, 13, 14) which are electrically insulated at an inside periphery of the insulated conveyance. The fuel-conditioning catalytic material is structured designedly for predeterminedly random contact of liquid fuel being conveyed intermediate an inlet end (4) and an outlet end (6) of the insulated conveyance. Optionally for conditioning particular liquid fuels, electrical current can be routed through the fuel-conditioning catalytic material.

Abstract: A water and fuel conditioning device includes a core or casting made of 40-66% copper, 2-30% zinc, 10-25% nickel, 2-5% tin, 0-1.5% iron and 0-2% lead, all percentages being by weight. Water flowing in contact with this core exhibits greater electrical charge than with prior art devices. The same composition is effective as a fuel conditioner to reduce emissions. In both applications, the near absence of lead has environmental advantages.
