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.
A gasoline engine burns a mix of gasoline and air, consisting of a range of about twelve to eighteen parts (by weight) of air to one part of fuel (by weight). A mixture with a 14.7:1 air/fuel ratio is stoichiometric, that is when burned, 100% of the fuel and the oxygen are consumed.
One standard was established for gasoline and the alternative fuels that can replace it, and a second similar standard is set for diesel fuel and its replacements. [30] The regulation is based on an average declining standard of carbon intensity that is expected to achieve 16 million metric tons of greenhouse gas emission reductions by 2020.
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]
The fuel specifications of petrol and diesel have been aligned with the Corresponding European Fuel Specifications for meeting the Euro II, Euro III and Euro IV emission norms. The BS IV grade fuel was introduced in 2010 and is available in 39 cities, as reported in 2016. The rest of the country has to make do with BS III fuel. [22]
The government undertook consultation on the model for the standard in April and May 2023, and they intend to introduce legislation by the end of 2023 [80] Research commissioned by environmental NGO Solar Citizens has calculated that a Fuel Efficiency Standard that started at 95g CO2/km and reduced to 0g CO2/km over ten years would save ...
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 ...
