Aviation kerosene is composed of hydrocarbon fractions including alkanes, aromatic hydrocarbons, and alkenes. According to GB 6537, the composition of No. 3 aviation kerosene is as follows. Permitted additives include antistatic agents, antioxidants, anti-wear agents, anti-icing agents, and metal deactivators. The additive components do not include the gasoline anti-knock additive tetraethyl lead, which produces solid lead oxide and lead during combustion, rapidly accumulating in the engine and damaging components.^[6]

Aviation kerosene features appropriate density, high calorific value, excellent combustion performance, high cleanliness, low sulfur content, and minimal corrosion to engine parts. It burns rapidly, steadily, and completely, meeting the fluidity requirements for oil products in cold regions and high-altitude flight.
