A study by engineers from Mahle Powertrain Ltd and BP found strong synergy between spark ignition (SI) engine downsizing and fuel containing low-to-moderate amounts of alcohol, including ethanol and butanol. The team presented a paper on their work at the recent SAE 2009 World Congress in Detroit. Cairns et al. SAE 2009-01-0138).

Alcohol and gasoline-alcohol blends also offer efficiency benefits independent of their octane value. Higher octane fuel improves the efficiency of today’s engines through reduced spark retard (from optimum) at high loads, and could enable even higher efficiency if engines were optimized for higher-octane fuel. Leone, James E.

RVPs (predicted DVPE) of single- and dual-alcohol blends in gasoline with different relative proportions of ethanol and 1-butanol. At high blending concentrations (70-85%), however, the propanols and butanols may produce problematically low RVPs. Resources. Nielsen (2010) Vapor Pressures of Alcohol-Gasoline Blends.
