Natural Gas Vehicles

Compressed natural gas (CNG) and liquefied natural gas (LNG) are considered alternative fuels under the Energy Policy Act of 1992. Natural gas vehicles (NGVs) are either fueled exclusively with CNG or LNG (dedicated NGVs) or are capable of natural gas and gasoline fueling (bi-fuel NGVs).
