    en.wikipedia.org/wiki/Compressed_natural_gas

    Compressed natural gas (CNG) is a fuel gas mainly composed of methane (CH 4), compressed to less than 1% of the volume it occupies at standard atmospheric pressure.It is stored and distributed in hard containers at a pressure of 20–25 megapascals (2,900–3,600 psi; 200–250 atm), usually in cylindrical or spherical shapes.

    en.wikipedia.org/wiki/Bivalent_(engine)

    Compressed natural gas (CNG) is made by compressing methane to store it at high pressures. Liquefied natural gas (LNG) is made and stored cryogenically, much like liquid hydrogen. The physical properties of natural gas require the compression ratio of the engine to be higher than in normal internal combustion engines, and the higher compression ...

    One GGE of natural gas is 126.67 cubic feet (3.587 m 3) at standard conditions. This volume of natural gas has the same energy content as one US gallon of gasoline (based on lower heating values: 900 BTU/cu ft (9.3 kWh/m 3) of natural gas and 114,000 BTU/US gal (8.8 kWh/L) for gasoline). [22]

  8. Natural gas vehicle - Wikipedia

    en.wikipedia.org/wiki/Natural_gas_vehicle

    Methane, the main component of natural gas, has an autoignition temperature of 580 °C, [47] whereas gasoline and diesel autoignite at approximately 250 °C and 210 °C respectively. With a compressed natural gas (CNG) engine, the mixing of the fuel and the air is more effective since gases typically mix well in a short period of time.
