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.

NOVEMBER 26, 2013

Results of a study led by a team from the National Renewable Energy Laboratory on the impact of butanol-gasoline blends on light-duty vehicle emissions suggest that widespread deployment of n-butanol or i-butanol in the gasoline pool could result in changes to the estimated emissions of alcohols and carbonyls in the emissions inventory.

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.

Researchers from Tsinghua University and Peking University have investigated the effects of fuel properties on particulate emissions gasoline direct injection engines (GDI). Higher aromatics in gasoline resulted in much higher PM (mass), PN (particle number) and PAHs emissions, with higher toxicity to human health. emissions in 2014.

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.

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.
