  2. United States vehicle emission standards - Wikipedia

    en.wikipedia.org/wiki/United_States_vehicle...

    The amount of carbon dioxide emitted per liter or gallon burned varies by fuel type, since each type of fuel contains a different amount of carbon per gallon or liter. The ratings reflect carbon dioxide (CO 2), nitrous oxide (N 2 O) and methane (CH 4) emissions, weighted to reflect each gas's relative contribution to the greenhouse effect.

  3. Fuel efficiency - Wikipedia

    en.wikipedia.org/wiki/Fuel_efficiency

    Fuel efficiency is dependent on many parameters of a vehicle, including its engine parameters, aerodynamic drag, weight, AC usage, fuel and rolling resistance. There have been advances in all areas of vehicle design in recent decades. Fuel efficiency of vehicles can also be improved by careful maintenance and driving habits. [3]

  4. European emission standards - Wikipedia

    en.wikipedia.org/wiki/European_emission_standards

    The purpose of Directive 1999/94/EC of the European Parliament and the Council of 13 December 1999 relating to the availability of consumer information on fuel economy and CO 2 emissions in respect of the marketing of new passenger cars [63] is to ensure that information relating to the fuel economy and CO 2 emissions of new passenger cars ...

    It will save about 887,000,000 U.S. gallons (3.36 × 10 9 L) of fuel and reduce carbon dioxide emissions by 8.3 million metric tons. This 2011 single-year standard will use an attribute-based system, which sets fuel economy standards for individual vehicle models, based on the footprint model.

    Retail markup over crude oil and wholesale gasoline, 2014–2019 Oil, gas, and diesel prices RBOB Gasoline Prices. In 2008, a report by Cambridge Energy Research Associates stated that 2007 had been the year of peak gasoline usage in the United States, and that record energy prices would cause an "enduring shift" in energy consumption practices.

  7. Emission standard - Wikipedia

    en.wikipedia.org/wiki/Emission_standard

    Many emissions standards focus on regulating pollutants released by automobiles (motor cars) and other powered vehicles.Others regulate emissions from industry, power plants, small equipment such as lawn mowers and diesel generators, and other sources of air pollution.

  8. Diesel fuel - Wikipedia

    en.wikipedia.org/wiki/Diesel_fuel

    Carbon dioxide has a molar mass of 44g/mol as it consists of 2 atoms of oxygen (16 g/mol) and 1 atom of carbon (12 g/mol). So 12 g of carbon yield 44 g of Carbon dioxide. Diesel has a density of 838 g per liter. Putting everything together the mass of carbon dioxide that is produced by burning 1 liter of diesel fuel can be calculated as:

  9. Fuel economy in automobiles - Wikipedia

    en.wikipedia.org/wiki/Fuel_economy_in_automobiles

    Fuel consumption monitor from a 2006 Honda Airwave.The displayed fuel economy is 18.1 km/L (5.5 L/100 km; 43 mpg ‑US). A Briggs and Stratton Flyer from 1916. Originally an experiment in creating a fuel-saving automobile in the United States, the vehicle weighed only 135 lb (61.2 kg) and was an adaptation of a small gasoline engine originally designed to power a bicycle.
