WebMay 8, 2014 · Ethanol boosts the octane number of fuel, which helps prevent pre-ignition knock. Incidentally, the octane rating system for fuels was originally developed by Penn State chemist Russell Marker in the 1920s. The octane rating (Anti-Knock Index, AKI) of normal unleaded gasoline in the United States is 87. Web0.097. κ = cp / cv - the specific heat capacity ratio. cp = specific heat in a constant pressure process. cv = specific heat in a constant volume process. R- Individual Gas constant.

Properties of aqueous ethanol solutions [ edit] Data obtained from Lange 1967 Boiling points of aqueous solutions [ edit] WebThe heat value of a fuel is the amount of heat released during its combustion. Also referred to as energy or calorific value, heat value is a measure of a fuel's energy density, and is expressed in energy (joules) per specified amount ( e.g. kilograms).
