Abstract: A fuel saving device comprising a support body (10) having at least one flow opening (15) therein and a periphery which adapts the support body (10) for positioning within a sealed environment of a fuel system of a combustion engine in a manner in which the longitudinal axis of the at least one flow opening (15) is coaxial with a fluid flow path, and a plurality of permanent magnets (11-14), the polar axes of all magnets oriented parallel to the flow path through the opening (15), the magnets (11-14) are provided in at least two stacks (16, 16?, each stack (16, 16? containing at least two magnets (11-14), the magnets (11-14) of each stack (16, 16?) each have a polar axis extending in the same direction with the magnets (11-14) of at least one stack (16) having polar axes extending in opposite direction to the other of the at least two stacks (16?).

Abstract: An emissions control device including an elongate body portion having a plurality of channels which are angularly orientated to each other, and each channel having at least one magnet positioned in the channel, the at least one magnet having a polar axis orientated to create magnetic fields directed at a common site adjacent to the body portion.
