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.

These top candidates, when blended with petroleum and used in a boosted spark ignition (BSI) engine, will offer environmental benefits and boost energy efficiency all while being available at a competitive price. These blendstocks are best-suited for light-duty (LD) gasoline BSI engines. Gaspar, Daniel J., West, Brian H., Pihl, Josh A.,

Alcohol and gasoline-alcohol blends also offer efficiency benefits independent of their octane value. Most regular-grade gasoline in the US is sold with a minimum octane rating of 87 AKI, corresponding to approximately 91−92 RON. Premium-grade gasoline is listed as 91−93 AKI minimum, corresponding to 96−98 RON.

In 1975, General Ernesto Geisel, then-president of Brazil, ordered the country’s gasoline supply mixed with 10% ethanol. The level was raised to 25% over the next five years, which was intended to maintain a constant Brazilian gasoline supply for an ever-increasing demand. These were arguably the first flex-fuel vehicles.

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.
