Patent ID: 7645305

Claim:
A high-stability, low emission, fuel emulsion composition for a reciprocating engine comprising: purified water being substantially 28-50% by weight of said fuel emulsion composition wherein water is a continuous phase of said fuel emulsion; hydrocarbon petroleum distillate being substantially 43-70% by weight of said fuel emulsion; and additives being at least 1% by weight of said fuel emulsion wherein said additives includes: an ignition delay modifier being substantially 0.1%-0.4% by weight of said fuel emulsion wherein said ignition delay modifier improves fuel detonation characteristics of said fuel emulsion and includes Ammonium Nitrate that acts as an emulsion stabilizer, a neutralizer being substantially 0.05%-0.4% by weight of said fuel emulsion wherein said neutralizer reduces corrosion caused by acids in said fuel emulsion, a coupling agent substantially 0.04%-0.1% by weight of said fuel emulsion wherein said coupling agent maintains phase stability of said fuel emulsion at high temperatures and shear pressures of an internal combustion engine and wherein said coupling agent is a water soluble salt formed from the neutralization reaction of an acid selected from a group consisting of: a di-acid of the Diels-Alder adducts of unsaturated fatty acids and a tri-acid of the Diels-Alder adducts of unsaturated fatty acids and an alkanolamine, and at least one additive selected from a group consisting of: a surfactant being substantially 0.3%-1% by weight of said fuel emulsion wherein said surfactant facilitates formation of a stable emulsion of said hydrocarbon distillate within said continuous phase of water, a lubricant being 0.04% to 0.1% by weight of said emulsion to improve lubricity of said fuel emulsion, a corrosion inhibitor being substantially 0.05% by weight of said fuel emulsion, and biocides being less than 0.0005% by weight of said fuel emulsion wherein said biocides are an anti-foam agent.
