Use of Supercritical Diesel Fuel for Improved Efficiency and Reduced Emissions

Green Car Congress

Researchers at Syracuse University (New York) have developed a method to prepare, inject and combust supercritical (SC) diesel fuel. George Anitescu from Syracuse presented the work in a poster at the DEER 2009 conference in Dearbon, Michigan. The fuel may coke for temperatures higher than 750 K (at the right of the red line).
