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]
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 ...
Methanol may be made from fossil fuels or renewable resources, in particular natural gas and coal, or biomass respectively. In the case of the latter, it can be synthesized from CO 2 ( carbon dioxide) and hydrogen. [ 3] The vast majority of methanol produced globally is currently made with gas and coal. [ 4]

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 ...
The parent company of Saks Fifth Avenue has signed a deal to buy upscale rival Neiman Marcus Group, which owns Neiman Marcus and Bergdorf Goodman stores, for $2.65 billion, with online behemoth ...
Shown below are the CNG storage tanks in the trunk. 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 ...
