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 (LPG), NGV's rely on methane combustion, resulting in cleaner emissions due to the removal of contaminants from the natural gas source.
An alternative fuel vehicle is a motor vehicle that runs on alternative fuel rather than traditional petroleum fuels ( petrol or petrodiesel ). The term also refers to any technology (e.g. electric cars, hybrid electric vehicles, solar-powered vehicles) powering an engine that does not solely involve petroleum. [citation needed]
Renewable natural gas. Renewable natural gas (RNG), also known as biomethane, is a renewable fuel and biogas which has been upgraded to a quality similar to fossil natural gas and has a methane concentration of 90% or greater. [ 1] By removing CO2 and other impurities from biogas, and increasing the concentration of methane to a level similar ...
Water injection has been used in both reciprocating and turbine aircraft engines. In a reciprocating engine, the use of water injection, also called anti-detonation injection or ADI, is used to prevent engine knocking also known as "detonation". [ 3] Commonly found on large radial engines with pressure carburetors, it is a mixture of water and ...
A Shell Autogas refuelling station. Autogas or LPG is liquefied petroleum gas (LPG) used as a fuel in internal combustion engines in vehicles as well as in stationary applications such as generators. It is a mixture of propane and butane . Autogas is widely used as a "green" fuel, as its use reduces CO 2 exhaust emissions by around 15% compared ...
A $1.3 billion chemical production facility to be built in Louisiana by Japanese conglomerate Mitsubishi is economically questionable and unnecessarily increases greenhouse gas emissions ...
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.
Bi-fuel vehicles are vehicles with multifuel engines capable of running on two fuels. The two fuels are stored in separate tanks and the engine runs on one fuel at a time. On internal combustion engines, a bi-fuel engine typically burns gasoline and a volatile alternate fuel such as natural gas (CNG), LPG, or hydrogen. [ 1]
