A natural gas vehicle (NGV) is a vehicle that utilizes compressed or liquefied natural gas (CNG/LNG) as a fuel source instead of conventional petroleum-based fuels. It is an alternative fuel vehicle designed to function with natural gas, which is composed mostly of methane.
Natural gas vehicles have gained popularity due to their environmental advantages over traditional gasoline or diesel-powered vehicles. They are considered more eco-friendly as they emit fewer greenhouse gas emissions and pollutants, such as carbon dioxide, nitrogen oxides, and particulate matter. This makes NGVs a favorable option for individuals and organizations seeking to reduce their carbon footprint and improve air quality.
NGVs can be powered by either compressed natural gas (CNG) or liquefied natural gas (LNG). CNG vehicles store natural gas at high pressure in specially designed cylinders, while LNG vehicles store it in cryogenic tanks as a low-temperature liquid. Both systems require specific fueling infrastructure, but CNG is more common and accessible.
Natural gas vehicles are typically converted from gasoline or diesel vehicles by adding or modifying certain components, including the fuel storage system, engine control unit, and fuel supply system. However, some manufacturers offer factory-built NGV models as well.
Overall, natural gas vehicles are a promising and greener alternative to conventional gasoline or diesel vehicles, offering reduced emissions and the potential for energy independence by utilizing a cleaner and domestically abundant fuel source.
