Study finds highly-turbocharged alcohol-fueled DISI engines could be more efficient than diesels

Green Car Congress

Highly turbocharged alcohol-fueled direct-injection spark-ignition (DISI) engines operated at a high compression ratio could be as or more efficient than diesel engines while also providing advantages of lower vehicle cost, lower emissions and higher power, according to a recent modeling study by Leslie Bromberg and Daniel Cohn at MIT.

Mazdas new SKYACTIV gasoline and diesel engines are steps on the road to its Ideal Engine; focus on compression ratio

Green Car Congress

Since this energy loss is primarily thermal in nature and can be attributed to the exhaust, cooling system, and engine and transmission surfaces, Mazda’s R&D team’s central focus is on improving the engine’s thermal efficiency cost-effectively. Extreme compression ratio rather than downsizing. Although downsizing—i.e.,

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.
