  2. Heat of combustion - Wikipedia

    en.wikipedia.org/wiki/Heat_of_combustion

    The heating value (or energy value or calorific value) of a substance, usually a fuel or food (see food energy), is the amount of heat released during the combustion of a specified amount of it. The calorific value is the total energy released as heat when a substance undergoes complete combustion with oxygen under standard conditions.

  3. Ethanol (data page) - Wikipedia

    en.wikipedia.org/wiki/Ethanol_(data_page)

    Ethanol (data page) provides detailed information about the chemical properties, physical properties, and safety measures of ethanol.

  4. Energy content of biofuel - Wikipedia

    en.wikipedia.org/wiki/Energy_content_of_biofuel

    Biofuels include bioethanol, an alcohol made by fermentation—often used as a gasoline additive, and biodiesel, which is usually used as a diesel additive. Specific energy is energy per unit mass, which is used to describe the chemical energy content of a fuel, expressed in SI units as joule per kilogram (J/kg) or equivalent units. [1]

  5. Ethanol - Wikipedia

    en.wikipedia.org/wiki/Ethanol

    Ethanol (also called ethyl alcohol, grain alcohol, drinking alcohol, or simply alcohol) is an organic compound with the chemical formula CH 3 CH 2 OH. It is an alcohol , with its formula also written as C 2 H 5 OH , C 2 H 6 O or EtOH, where Et stands for ethyl .

  6. Ethanol fuel - Wikipedia

    en.wikipedia.org/wiki/Ethanol_fuel

    Ethanol fuel has a "gasoline gallon equivalency" (GGE) value of 1.5, i.e. to replace the energy of 1 volume of gasoline, 1.5 times the volume of ethanol is needed. [4] [5] Ethanol-blended fuel is widely used in Brazil, the United States, and Europe (see also Ethanol fuel by country). [2]

  7. Gasoline gallon equivalent - Wikipedia

    en.wikipedia.org/wiki/Gasoline_gallon_equivalent

    Pure ethanol provides 2/3 of the heat value available in pure gasoline. In the most common calculation, that is, the BTU value of pure gasoline vs gasoline with 10% ethanol, the latter has just over 96% BTU value of pure gasoline.

  8. Alcohol fuel - Wikipedia

    en.wikipedia.org/wiki/Alcohol_fuel

    The 3-carbon alcohol, propanol (C 3 H 7 OH), is not often used as a direct fuel source for petrol engines (unlike ethanol, methanol and butanol), with most being directed into use as a solvent. However, it is used as a source of hydrogen in some types of fuel cell; it can generate a higher voltage than methanol, which is the fuel of choice for ...

    en.wikipedia.org/wiki/Table_of_specific_heat...

    The specific heat of the human body calculated from the measured values of individual tissues is 2.98 kJ · kg−1 · °C−1. This is 17% lower than the earlier wider used one based on non measured values of 3.47 kJ · kg−1· °C−1.
