Most liquid fuels in widespread use are derived from the fossilized remains of dead plants and animals by exposure to heat and pressure in the Earth's crust. However, there are several types, such as hydrogen fuel (for automotive uses), ethanol, jet fuel and biodiesel which are all categorized as a liquid fuel.
Jet fuel, aviation turbine fuel (ATF), or avtur, is a type of aviation fuel designed for use in aircraft powered by gas-turbine engines. It is colourless to straw-colored in appearance.he first axial compressor jet engine in widespread production and combat service, the Junkers Jumo 004 on the Messerschmitt Me 262 A fighter, and the Arado Ar 234 B jet recon-bomber, burned either a special synthetic J2 fuel or diesel fuel. Gasoline was a third option but unattractive due to high fuel consumption.
