Method of combusting fuel in an internal combustion engine and its apparatus

In an internal combustion engine having a cylinder section, a fuel supply, means for injecting fuel from said fuel supply into said cylinder section for combustion therein, and means for directing fuel along a path from said fuel supply to said injecting means, the improvement comprising means for applying a strong magnetic field to the fuel at a location in one of a segment of said path and said fuel injecting means, said magnetic field applying means including a tubular ferromagnetic yoke and a first plate-shaped permanent magnet disposed in said yoke so as to define fuel flow passages on respective opposite sides of said first magnet between the opposite side faces of said first magnet and the inner walls of said yoke, said first magnet having its north and south poles at said respective side faces, so that the fuel flows through said fuel flow passages to be subjected to a strong magnetic field therealong the fuel flow through one of said fuel flow passages being subjected only to a northern magnetic field and the other fuel flow through the other fuel flow passage being subjected only to a southern magnetic field.
