  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.

    Chapter 5, Section 5.1 "Petroleum Refining" discusses the air pollutant emissions from the equipment in the various refinery processing units as well as from the auxiliary steam-generating boilers, furnaces and engines, and Table 5.1.1 includes the pertinent emission factors.

  7. 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]

    A rush by U.S. fuel makers to recalibrate their plants to produce renewable diesel has created a supply glut for low-emissions biofuels, hammering profit margins for refiners and threatening to ...

  9. 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:
