US Patent 7351337 Magnetic fuel conditioning apparatus

A fuel conditioning apparatus includes a housing having an interior chamber that extends between an inlet and an outlet. The chamber is surrounded by a threaded channel that is formed in an interior wall of the housing. A plurality of permanent magnets are carried within the chamber of the housing interiorly of the threaded channel. Like poles of adjacent magnets face one another such that each pair of adjacent magnets repel one another and define a mixing pocket that is in communication with the channel. Fuel is transmitted through the channel and the mixing pockets. Magnetic flux generated by the magnets induces energy within the fuel to resist repolymerization and the formation of particulates in the fuel.
