Patent ID: 8517000

Claim:
A method for increasing the combustion efficiency of fuel in a fuel-injected, internal combustion engine, said engine having a fuel intake line that conducts fuel from a fuel source to one or more fuel injectors of said engine, comprising the steps of: preheating the fuel at a first location intermediate said fuel source and said fuel injectors to a temperature within an optimal temperature range as experimentally determined for maximum efficiency of combustion of said fuel when said fuel is combusted according to said method, thereby producing preheated fuel; at a second location intermediate said fuel source and said fuel injectors, conducting said preheated fuel through a bidirectional, dual helical pathway disposed within a housing comprising a magnetically-susceptible metal, wherein said pathway includes a first tube segment comprising a magnetically-susceptible metal that extends helically about a helical axis from a top end to a bottom end thereof in a first rotational sense, said top end receiving fuel into said pathway; and a second tube segment comprising a magnetically-susceptible metal that extends helically about said helical axis from a bottom end to a top end thereof in said first rotational sense, said bottom end of the second tube segment being continuous and in communication with the bottom end of the first tube segment, and said top end of said second tube segment being adjacent or near to the top end of the first tube segment; at said second location, at the same time that the preheated fuel is being conducted through said dual helical pathway, subjecting said preheated fuel to a magnetic field, wherein said magnetic field is created by first and second magnets spaced apart along said helical axis on opposite ends of said pathway and abutting opposite, interior surfaces of said housing; said dual helical pathway is coaxially disposed between said magnets, said first and second magnets have either their north poles or their south poles facing each other; and conducting the preheated, magnetic field treated fuel from the top end of the second tube segment to said one or more fuel injectors.
