  2. Butanol fuel - Wikipedia

    en.wikipedia.org/wiki/Butanol_fuel

    The fuel in an engine has to be vaporized before it will burn. Insufficient vaporization is a known problem with alcohol fuels during cold starts in cold weather. As the heat of vaporization of butanol is less than half of that of ethanol, an engine running on butanol should be easier to start in cold weather than one running on ethanol or ...

    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 ...

  4. Butanol - Wikipedia

    en.wikipedia.org/wiki/Butanol

    Butanol (also called butyl alcohol) is a four-carbon alcohol with a formula of C 4 H 9 O H, which occurs in five isomeric structures (four structural isomers), from a straight-chain primary alcohol to a branched-chain tertiary alcohol; [1] all are a butyl or isobutyl group linked to a hydroxyl group (sometimes represented as BuOH, sec-BuOH, i-BuOH, and t-BuOH).

    1952 Shell Oil film showing the development of the diesel engine from 1877. The diesel engine, named after the German engineer Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is called a compression-ignition engine (CI engine).

  6. 1-Butanol - Wikipedia

    en.wikipedia.org/wiki/1-Butanol

    1-Butanol, also known as butan-1-ol or n-butanol, is a primary alcohol with the chemical formula C 4 H 9 OH and a linear structure. Isomers of 1-butanol are isobutanol, butan-2-ol and tert-butanol. The unmodified term butanol usually refers to the straight chain isomer.

  8. Heat of combustion - Wikipedia

    en.wikipedia.org/wiki/Heat_of_combustion

    In all, the higher heating value of hydrogen is 18.2% above its lower heating value (142 MJ/kg vs. 120 MJ/kg). For hydrocarbons, the difference depends on the hydrogen content of the fuel. For gasoline and diesel the higher heating value exceeds the lower heating value by about 10% and 7%, respectively, and for natural gas about 11%.

  9. Diesel fuel - Wikipedia

    en.wikipedia.org/wiki/Diesel_fuel

    Diesel fuel has many colloquial names; most commonly, it is simply referred to as diesel.In the United Kingdom, diesel fuel for road use is commonly called diesel or sometimes white diesel if required to differentiate it from a reduced-tax agricultural-only product containing an identifying coloured dye known as red diesel.
