  • Hydrocarbon based fluid fuels with which the device may be used include petrol, diesel, paraffin, liquid petroleum gas, natural gas, fuel oil and nitromethane.
  • the apparatus may be, for example, any type of internal combustion engine, industrial or marine steam raising plant or an aviation propulsion unit.

  • a cylindrical rod 55 is positioned longitudinally along the centreline of the chamber 50.
  • the rod 55 is preferably manufactured from mild steel and acts as a bridge which has the effect of reducing the leakage field from 4 inches to 1/16th of an inch.

  • the rows 75, 80, 85 may be surmounted by a three sided mild steel bridge 90.
  • the height of the bridge 90 above the rows 75, 80, 85 is calculated as 1.5 times the total width of the magnetic elements composing the outermost two rows 75, 85. Hence if the total width of the outer two rows 75, 85 is 6mm then the roof 95 of the bridge 90 should be 9mm above the magnetic elements 70.

  • the length of the bridge may exceed the overall dimensions of the accumulative magnets.
  • the width of the bridge is varied to the overall strength of the magnetic gauss field thus transferring leakage from the north to the south faces which increases the overall gauss field.

Ladite chambre comprend au moins une canalisation (5) d'alimentation et au moins une canalisation (10) de sortie communiquant avec ladite zone de rétention pour permettre au fluide de couler à travers la zone de rétention. La plus grande dimension transversale de la zone de rétention est plus grande que la dimension transversale de la canalisation de sortie. Ledit dispositif comporte également un système (30, 45, 60, 70) pour appliquer un champ magnétique au combustible retenu dans la zone de rétention ainsi qu'un pont (90) entourant le système pour appliquer le champ magnétique, le pont facilitant la concentration du champ magnétique dans la région de la zone de rétention.
