Among their findings was that for gasoline fuels, aggressively downsizing the engine and adopting homogeneous direct fuel injection enabled an improvement in fuel consumption of ~17% over the New European Drive Cycle compared to a naturally aspirated PFI unit.

fuel with higher ethanol content—for part- and full-load operation for different engine types and fuel assumptions. Alcohol and gasoline-alcohol blends also offer efficiency benefits independent of their octane value. Premium-grade gasoline is listed as 91−93 AKI minimum, corresponding to 96−98 RON.

RVPs (predicted DVPE) of single- and dual-alcohol blends in gasoline with different relative proportions of ethanol and 1-butanol. As part of the study, they demonstrated a simple method to prepare dual-alcohol-gasoline blends with Reid vapor pressures (RVPs) “ indistinguishable ” from that of the base gasoline.
