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 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.
GM-1. GM-1 ( Göring Mischung 1) was a system for injecting nitrous oxide (laughing gas) into aircraft engines that was used by the Luftwaffe in World War II. This increased the amount of oxygen in the fuel mixture, and thereby improved high-altitude performance. GM-1 was used on a number of modifications of existing fighter designs in order to ...
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 ...
Diesel engines converted to use gaseous fuels fall into this class due to the different ignition system. The most common technology and alternate fuel available in the market for bi-fuel gasoline cars is Autogas (LPG), followed by natural gas (CNG), [6] and it is used mainly in Europe. Poland, the Netherlands, and the Baltic states have many ...
