Kerosene is a section of crude oil whose boiling range is immediately after gasoline and contains hydrocarbons C10 to C14. The boiling point of this oil cut is approximately 190˚C to 270˚C. Jet fuel and kerosene are both subsets and products of kerosene. These compounds are colorless and can have different uses.

Among the applications of kerosene that were very common in the past is the use as fuel for oil heaters and lighting fixtures. Today, with the expansion of the use of city gas and electricity, such applications are less significant. Kerosene is also a fuel used in tractors and some agricultural machinery, which is obtained from refining crude oil in refineries.

Jet engines in all types of aircraft, helicopters and all aircraft equipment use a fuel called jet fuel, which must have special conditions and are refueled by different fuel tanks. Aircraft engines have a different structure to car piston cylinder engines. In these engines, acceleration in the air creates a force called the Trust, and this force actually causes the necessary thrust in the aircraft.
