Patent ID: 6901917

Claim:
A method of improving the fuel economy and emission outputs of a combustion engine, the method including the step of i. interposing a fuel saving device within an air/fuel environment at or after an air/fuel mixing point of a fuel system for the engine characterized in that the fuel saving device comprises; a. a non-magnetic body having i. an opening therein having an axial dimension and a radial dimension and defining an air/fuel flow pathway, ii. the axial dimension of the opening co-axial with flow pathway within the air/fuel environment, and b. at least three magnets, each magnet having a polar axis oriented substantially parallel to the flow pathway, at least two said magnets being substantially opposed, the polar axis of the opposed magnets being in the same direction, with the at least third magnet's polar axes being in the opposite direction, the at least three magnets positioned to provide multiple overlapping and interacting fields of magnetic force, such that the air/fuel mixture is subjected to more than one magnetic field as it passes through the opening.
