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.

California’s current LEV II emission standards run through 2010. We see dramatic downsizing and boosting [as] something that’s going to for gasoline engines especially. To be able effectively to implement downsizing and downspeeding, good low-end torque is essential. Differentiated Analysis of Downsizing Concepts”).

A recent white paper by Leslie Bromberg of MIT’s Plasma Science and Fusion Center and Wai K. Researchers at the US EPA investigating this approach concluded that the M85 and E85 engines could provide efficiencies comparable or higher than the diesel, in dedicated fuel, high compression ratio turbo charged/downsized engines.

GM has announced plans for public sales in 2010, and almost every carmaker now says it will sell PHEVs or highway-speed battery electric vehicles (BEVs) sometime after 2010. Committed to sales of 10,000 or more vehicles in late 2010, with increasing production in 2011. Aims to get Saturn Vue on road in 2010; no production goal.
