Natural gas vehicle. Truck running with Guidetti CNG system. Fueling (Fiat Multipla) 2009 Honda Civic GX hooked up to Phill refueling fuel system. A natural gas vehicle (NGV) utilizes compressed natural gas (CNG) or liquefied natural gas (LNG) as an alternative fuel source. Distinguished from autogas vehicles fueled by liquefied petroleum gas ...
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 ...
Two sets, or tiers, of emission standards for light-duty vehicles in the United States were defined as a result of the Clean Air Act Amendments of 1990. The Tier I standard was adopted in 1991 and was phased in from 1994 to 1997. Tier II standards were phased in from 2004 to 2009. Within the Tier II ranking, there is a subranking ranging from ...
Gas cylinder. For the mechanical devices used to impart a force from a pressurized gas, see pneumatic cylinder. For the large structures used to store town gas, see gas holder. Industrial compressed gas cylinders used for oxy-fuel welding and cutting of steel. A gas cylinder is a pressure vessel for storage and containment of gases at above ...
Natural gas (also called fossil gas, methane gas or simply gas) is a naturally occurring mixture of gaseous hydrocarbons consisting primarily of methane (95%) [ 1 ] in addition to various smaller amounts of other higher alkanes. Traces of carbon dioxide, nitrogen, hydrogen sulfide, and helium are also usually present. [ 2 ]
Maximum Allowable Operating Pressure (MAOP) is a pressure limit set, usually by a government body, which applies to compressed gas pressure vessels, pipelines, and storage tanks. For pipelines, this value is derived from Barlow's Formula , which takes into account wall thickness, diameter, allowable stress (which is a function of the material ...
Natural-gas condensate, also called natural gas liquids, is a low-density mixture of hydrocarbon liquids that are present as gaseous components in the raw natural gas produced from many natural gas fields. Some gas species within the raw natural gas will condense to a liquid state if the temperature is reduced to below the hydrocarbon dew point ...
Width. 69.0 in (1,753 mm) Height. 56.5 in (1,435 mm) The Honda Civic GX is the only car factory-built to run on compressed natural gas (CNG) in the United States available to non-fleet customers. [1] The GX was based on the Honda Civic and available for fleet sales in all 50 states. It was previously available for retail sales in four states ...
