Abstract: The present invention relates to a combination of components suitable to break down liquid fuels into short chain molecules and gaseous states of matter by heating and pressurizing the combustible/flammable liquids to the point where they phase change into a supercritical fluid, then releasing some fluid as needed into a vapor accumulation tank that has a lower pressure. This subsequent drop in pressure phase changes the fluid from a supercritical state into a consistent and safe gaseous state. From there, the fuel can be delivered to the engine via direct injectors, gaseous fuel carburetors, or a regulating valve such as a needle valve. Because gaseous fuels readily homogenize with intake air and oxidizers, the present invention allows any engine to cleanly, reliably, and consistent use any fuel without adjustment. This allows any engine to run off any combustible liquid, in effect creating the ultimate multifuel system.

Abstract: A method for supercritical diesel combustion combines fumigation and supercritical diesel fuel combustion to effect greater fuel efficiency and reduce exhaust gas pollutants from a compression ignition engine. The invention utilizes the fumigant method by combining two gases (DME and propane) which autoignite prior to the injection of the liquid diesel fuel. This pre-combustion of the fumigant gases combined with the engine's compression of the combustion chamber gases is managed to attain a supercritical combustion chamber environment into which the liquid diesel fuel is injected. This targeted supercritical combustion chamber environment causes the diesel fuel to become a supercritical fluid prior to combustion, resulting in significantly greater efficiency and negligible exhaust gas pollutants resulting from the combustion of the diesel fuel.
