DOE Co-Optima report identifies top ten bio-blendstocks for efficiency in boosted SI engines

Green Car Congress

This work will help the research community better understand the efficiencies that biofuels bring to the table, and identifies the biofuels that enable more efficient engine design and operation. George, Anthe, Monroe, Eric, Davis, Ryan W., These blendstocks are best-suited for light-duty (LD) gasoline BSI engines. Gaspar, Daniel J.,

Team from GM, Ford, FCA reviews how to calculate engine efficiency benefits of high octane fuels

Green Car Congress

The preflame reactions are a strong function of temperature, so evaporative cooling from the fuel can also play a significant role, which is particularly important for fuels containing alcohol. Alcohol and gasoline-alcohol blends also offer efficiency benefits independent of their octane value. —Leone et al.
