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. Heat required to bring the fuel to SC states is recovered from the exhaust gas of the engine. To attenuate that risk, the researchers use a diluent such as CO 2 , H 2 O or exhaust gas. Anitescu et.
