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.
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 ...
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.
• More than $1 trillion in revenue for federal, state, and local governments; • Lower energy prices for job creators and middle-class families; and • National security strengthened by freedom from dependence on foreign energy supplies. A successful national energy strategy will have a fundamental influence on the well-being of the nation.
The Volvo 7900 is an integrally-constructed single-decker rigid bus and single-decker articulated bus, most commonly available as a hybrid electric bus named Volvo 7900 Hybrid or just Volvo 7900H, but is also available with both diesel and Compressed Natural Gas (CNG) engines in some markets.
The Brazilian Fiat Siena Tetrafuel 1.4, the first multifuel car that runs as a flexible-fuel on pure gasoline, or E25, or E100; or runs as a bi-fuel with natural gas (CNG). High-pressure compressed natural gas (CNG), mainly composed of methane, that is used to fuel normal combustion engines instead of gasoline. Combustion of methane produces ...

Compressed natural gas (CNG) carrier ships are those designed for transportation of natural gas under high pressure. [1] CNG carrier technology relies on high pressure, typically over 250 bar (2900 psi ), to increase the density of the gas, but it is still 2.4 times less than that of LNG (426 kg/m 3 ). [ 2 ]
