Use of Supercritical Diesel Fuel for Improved Efficiency and Reduced Emissions

Green Car Congress

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. George Anitescu from Syracuse presented the work in a poster at the DEER 2009 conference in Dearbon, Michigan. At SC conditions, however (T?450
