  2. Corporate average fuel economy - Wikipedia

    en.wikipedia.org/wiki/Corporate_average_fuel_economy

    The program covered model year 2012 to model year 2016 and ultimately required an average fuel economy standard of 35.5 miles per US gallon (6.63 L/100 km; 42.6 mpg ‑imp) in 2016 (of 39 miles per gallon for cars and 30 mpg for trucks), a jump from the 2009 average for all vehicles of 25 miles per gallon. Obama said, "The status quo is no ...

  3. 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.

  4. Standard temperature and pressure - Wikipedia

    en.wikipedia.org/wiki/Standard_temperature_and...

    The molar volume of gases around STP and at atmospheric pressure can be calculated with an accuracy that is usually sufficient by using the ideal gas law. The molar volume of any ideal gas may be calculated at various standard reference conditions as shown below: V m = 8.3145 × 273.15 / 101.325 = 22.414 dm 3 /mol at 0 °C and 101.325 kPa

  5. Density of air - Wikipedia

    en.wikipedia.org/wiki/Density_of_air

    At IUPAC standard temperature and pressure (0 °C and 100 kPa), dry air has a density of approximately 1.2754 kg/m 3. At 20 °C and 101.325 kPa, dry air has a density of 1.2041 kg/m 3. At 70 °F and 14.696 psi, dry air has a density of 0.074887 lb/ft 3.

  6. Ford Power Stroke engine - Wikipedia

    en.wikipedia.org/wiki/Ford_Power_Stroke_engine

    The 7.3 L DI Power Stroke was in production until the first quarter of model year 2003, when it was replaced by the 6.0 L. Nearly 2 million 7.3 L DI Power Stroke engines were produced in International's Indianapolis plant. [8] The 7.3 L DI Power Stroke engine is commonly referred to as one of the best engines that International produced. [6] [7]

  7. Flammability limit - Wikipedia

    en.wikipedia.org/wiki/Flammability_limit

    A 5% displayed LFL reading for methane, for example, would be equivalent to 5% multiplied by 4.4%, or approximately 0.22% methane by volume at 20 degrees C. Control of the explosion hazard is usually achieved by sufficient natural or mechanical ventilation, to limit the concentration of flammable gases or vapors to a maximum level of 25% of ...

  8. Chrysler Hemi engine - Wikipedia

    en.wikipedia.org/wiki/Chrysler_Hemi_engine

    The top five finalists include HEMI Snowblower, HEMI-Go-Round carousel, "HEMI on Ice" ice resurfacer, HEMI-Shredder, and HEMI Big Wheel (i.e., the child's tricycle of the 1970s). [ 35 ] [ 36 ] [ 37 ] The winner was the HEMI Big Wheel, which had a 5.7 L Hemi in the back that was installed backwards; thus, reverse became the only forward gear.

  9. Lapse rate - Wikipedia

    en.wikipedia.org/wiki/Lapse_rate

    In dry air, the adiabatic lapse rate (i.e., decrease in temperature of a parcel of air that rises in the atmosphere without exchanging energy with surrounding air) is 9.8 °C/km (5.4 °F per 1,000 ft). The saturated adiabatic lapse rate (SALR), or moist adiabatic lapse rate (MALR), is the decrease in temperature of a parcel of water-saturated ...
