Higher octane ratings correlate to higher activation energies: the amount of applied energy required to initiate combustion. (en.wikipedia.org)
Many people are unaware that ethanol is has an extremely high octane rating, typically over 105, while high - grade gasoline rarely exceeds 93. (autoline.tv)
Using higher volume blends of ethanol to leverage the alcohol's inherent high octane rating to produce ethanol - gasoline blends with higher octane numbers could yield «substantial societal benefits», according to a team of researchers from Ford Motor Company. (greencarcongress.com)
