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.

Proposed by John Heywood and colleagues at MIT in 2005, the basic premise of E85 boosting is that ethanol (or other lower alcohols) suppresses knock due to the large evaporative cooling effect it has on the air-fuel mixture when injected directly into the cylinder, supplemented by ethanol’s inherent high octane number.

A recent white paper by Leslie Bromberg of MIT’s Plasma Science and Fusion Center and Wai K. Methanol first surfaced as a potentially interesting transportation fuel in the wake of the oil crisis in 1973. The early interest resulted in several programs, mainly based in California, for its use.

The more efficient combustion engine technologies, with their enabling of downsizing, come in compatibly with hybridization, with hybridization and electrification playing a larger role over time. The further downsized next-generation technologies can be very synergistic within hybrid applications. Planning background.
