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

Green Car Congress

These blendstocks are best-suited for light-duty (LD) gasoline BSI engines. The merit function determines potential improvements in engine efficiency, was used to evaluate the performance of candidate bio-blendstocks in blends up to 30%. The blendstocks were identified using a fuel property basis using the BSI merit function.

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

Green Car Congress

A higher compression ratio can be used if an engine will operate primarily at light loads, such that degraded efficiency at high loads is more than offset by improved efficiency at light loads. Alcohol and gasoline-alcohol blends also offer efficiency benefits independent of their octane value.
