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]
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 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.
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 ...
As of 2017, there were more than 21 million E85 flex-fuel vehicles in the United States, [ 1] up from about 11 million flex-fuel cars and light trucks in operation as of early 2013. [ 20][ 21] The number of flex-fuel vehicles on U.S roads increased from 1.4 million in 2001, to 4.1 million in 2005, and rose to 7.3 million in 2008. [ 3][ 19] E85 ...

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 ...
The fuel cartridge stores the methanol fuel. Depending on the system design either 100% methanol (IMPCA industrial standard) or a mixture of methanol with up to 40 vol% water is usually used as fuel for the RMFC system. 100% methanol results in lower fuel consumption than water-methanol mixture (Premix) but goes along with higher fuel cell system complexity for condensing of cathode moisture.
