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. In comparison, they noted, the technology for bio-chemical ethanol production from cellulosic biomass is not sufficiently developed yet. A full comparison between the different options has to be done, reflecting the present conditions.
