Compressed Natural Gas (CNG) in Fueled Systems and the Significance of CNG in Vehicular Transportation

Most NG vehicles operate using compressed natural gas (CNG). CNG's popularity stems, in part, from its clean-burning properties. In addition, more than 85,000 CNG vehicles, including one out of every five transit buses, are operating successfully today. This compressed gas is stored in similar fashion to a car's gasoline tank, attached to the rear, top, or undercarriage of the vehicle in a tube-shaped storage tank. A CNG tank can be filled in a similar manner, and in a similar amount of time, to a gasoline tank.
