Summary of significant emissions results from the fuel testing. Given equivalent deployment of butanols and ethanol, the results suggest emissions of unburned alcohols would decrease, but carbonyl emissions would increase; some of these compounds have poorly understood health effects, they note.

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.

This research involves identifying the fuel properties and engine parameters that mitigate knock and emissions, while maximizing boosted SI efficiency and performance. Of the fuel properties investigated, these six were found to have the most impact on engine efficiency and emissions. What Fuels Should We Make?

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.
