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.

In an informational webinar in September, John Farrell, Laboratory Program Manager—Vehicle Technologies, National Renewable Energy Laboratory, and part of the Co-Optima leadership team observed that: Put most simply, the Co-Optima goal is to introduce better fuels and better vehicles sooner. Fuel impacts on low speed pre-ignition.

converted all vehicle efficiency measurements into vehicle energy efficiency (VEE, km/MJ) based on fuel energy densities reported in each study. This is because the ethanol component may affect the conversion efficiency of the gasoline component in a blend, that is, make an engine more or less efficient in its use of the gasoline component.
