  2. Energy efficiency in transport - Wikipedia

    en.wikipedia.org/wiki/Energy_efficiency_in_transport

    Assuming the Emma Maersk consumes diesel (as opposed to fuel oil which would be the more precise fuel) then 1 kg diesel = 1.202 litres = 0.317 US gallons. This corresponds to 46,525 kJ. Assuming a standard 14 tonnes per container (per teu) this yields 74 kJ per tonne-km at a speed of 45 km/h (24 knots).

  3. Diesel fuel - Wikipedia

    en.wikipedia.org/wiki/Diesel_fuel

    Due to the higher density, diesel fuel offers a higher volumetric energy density: the density of EN 590 diesel fuel is defined as 0.820 to 0.845 kg/L (6.84 to 7.05 lb/US gal) at 15 °C (59 °F), about 9.0-13.9% more than EN 228 gasoline (petrol)'s 0.720–0.775 kg/L (6.01–6.47 lb/US gal) at 15 °C, which should be put into consideration when ...

  4. Fuel efficiency - Wikipedia

    en.wikipedia.org/wiki/Fuel_efficiency

    Traditionally, litres per mil were used in Norway and Sweden, but both have aligned to the EU standard of L/100 km. [1] Fuel consumption is a more accurate measure of a vehicle's performance because it is a linear relationship while fuel economy leads to distortions in efficiency improvements. [ 2 ]

  5. Energy density - Wikipedia

    en.wikipedia.org/wiki/Energy_density

    Liquid hydrocarbons (fuels such as gasoline, diesel and kerosene) are today the densest way known to economically store and transport chemical energy at a large scale (1 kg of diesel fuel burns with the oxygen contained in ≈ 15 kg of air). Burning local biomass fuels supplies household energy needs (cooking fires, oil lamps, etc.) worldwide.

  6. Energy content of biofuel - Wikipedia

    en.wikipedia.org/wiki/Energy_content_of_biofuel

    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] Energy density is the amount of chemical energy per unit volume of the fuel, expressed in SI units as joule per litre (J/L) or equivalent units. [2]

  7. Gasoline gallon equivalent - Wikipedia

    en.wikipedia.org/wiki/Gasoline_gallon_equivalent

    A diesel cycle engine can be as much as 40% to 50% efficient at converting fuel into work, [2] where a typical automotive gasoline engine's efficiency is about 25% to 30%. [3] [4] In general, an engine is designed to run on a single fuel source and substituting one fuel for another may affect the thermal efficiency.

  8. Diesel exhaust - Wikipedia

    en.wikipedia.org/wiki/Diesel_exhaust

    While diesel fuel contains slightly more carbon (2.68 kg CO 2 /litre) than petrol (2.31 kg CO 2 /litre), overall, the CO 2 emissions of a diesel car tend to be lower due to higher efficiency. In use, on average, this equates to around 200 g CO 2 /km for petrol and 120 g CO 2 /km for diesel.

  9. Liquid fuel - Wikipedia

    The number of 2.63 kg of carbon dioxide from 1 liter of Diesel is close to the values found in the literature. For gasoline, with a density of 0.75 kg/L and a ratio of carbon to hydrogen atoms of about 6 to 14, the estimated value of carbon emission if 1 liter of gasoline is burnt gives:
