Abstract

Abstract The invention is a means and method of injecting fuel into the cylinders of an internal combustion engine wherein the fuel is introduced under pressure to each cylinder through a metallic fuel tube having an integral and preferably multiplyorificed nozzle thereon, the tube and nozzle being charged to a high electrical potential, causing injected fuel to assume a charge and be repelled from the nozzle in small droplets which in turn disperse into smaller droplets due to internal repulsion created by the charge, the result being the rapid and thorough atomization of fuel so that quick and more complete combustion will occur. The applied charge may be reversed at the end of the injection cycle to cause current flow between the droplets and the oppositely charged nozzles to ignite, or further speed combustion of, the mixture.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 70 words
A method for injecting fuel in an electrically charged condition into a cylinder of an internal combustion engine comprising: a. injecting pressurized fuel through an electrically conductive fuel nozzle during a portion of the cycle of said engine; b. charging said nozzle to one polarity during the introduction of fuel therethrough, and reversing the polarity of the charge on said nozzle substantially at the termination of the fuel injection phase.
Claim 2
Independent Claim 70 words
A method for injecting fuel in an electrically charged condition into a cylinder of an internal combustion engine comprising: a. injecting pressurized fuel through an electrically conductive fuel nozzle during a portion of the cycle of said engine; b. charging said nozzle to one polarity during the introduction of fuel therethrough, and reversing the polarity of the charge on said nozzle substantially at the termination of the fuel injection phase.
Claim 3
Dependent Claim 31 words
A method according to claim 1 wherein said fuel nozzle is connected to a conductive charged fuel line, and step (a) includes the forcing of pressurized fuel through said fuel tube.
Claim 4
Dependent Claim 22 words
The method according to claim 1 wherein said fuel nozzle contains a plurality of divergent fuel passageways directed in substantially opposite directions.
Claim 5
Dependent Claim 49 words
The method according to claim 3 wherein said nozzle is provided with a plurality of generally radially directed protrusions, and each of said fuel passageways passes through and exits from a respective one of said protrusions, whereby an electrical field emanating from said nozzle is concentrated at said protrusion.
