Jet fuels are kerosene fractions or mixtures of kerosene and gasoline fractions with various additives. In principle, these are complex mixtures consisting of four basic groups of hydrocarbons: paraffin, naphthenic, aromatic and olefin. Today, JET A-1 fuel is in use in our area, which is a kerosene fraction of oil with a boiling temperature in the temperature range from 170°C to 300°C (in terms of its quality it meets the requirements of military and civil aviation). Lubricants used in aviation are facing today, and in the future will face serious challenges, the biggest challenge of which is heat, since modern engine housings reach lubricant temperatures between 80°C and 100° C, while during cleaning this temperature rises to approximately 190°C. In ensuring the safe operation of jet engines in all modes and in all conditions of application of fuels and lubricants must have a safe quality. Gases and particles produced by combustion of jet fuel are: water vapor, H2O, carbon dioxide, CO2, nitrogen monoxide, NO, nitrogen dioxide, NO2, sulfur oxides, SOx and soot.
