Abstract
Abstract In combusting fuel in an internal combustion engine with a fuel combustion system having a fuel tank, a fuel injecting system for injecting fuel into a cylinder section and a fuel path for providing fluid communication between the fuel tank and the fuel injecting system, a magnetic field is applied, by means of a magnetic field applying device, to the fuel flowing from the fuel tank to the fuel injecting system through the fuel path. The magnetic field applying device is provided either along the fuel path or in the fuel injecting system.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
193 words
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.
Claim 2
Dependent Claim
193 words
