Abstract: A method for superheated glycerin combustion (SGC) combines fumigation and SGC to effect greater fuel efficiency and reduce exhaust gas pollutants from a compression ignition engine such as a diesel engine. The invention utilizes the fumigant method by combining two gases (dimethyl ether and propane) which autoignite prior to the injection of the liquid glycerin water solution (GWS) 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 GWS fuel is injected. This targeted supercritical combustion chamber environment causes the GWS fuel to first vaporize the water which leaves the glycerin, prior to combustion, as highly dispersed monomers within the combustion chamber which autoignite similar to a “homogenous charge compression ignition” (HCCI) event resulting in significantly greater efficiency and negligible exhaust gas pollutants.
