What type of fuel is primarily used in jet engines?

Jet engines primarily operate using jet fuel, specifically Jet A or Jet A-1, due to their chemical composition and properties that are specially suited for high-performance aviation applications. Jet A and Jet A-1 are kerosene-based fuels, which provide excellent energy density, consistent performance at various temperatures, and a lower risk of freezing at high altitudes compared to other fuels.

These types of fuel are also formulated to minimize the formation of ice and have additives that prevent microbial growth and ensure stability during long-term storage. The specific characteristics of Jet A and Jet A-1 make them viable for the consistent high-energy requirements of jet engines, ensuring efficient combustion and optimal engine performance.

While kerosene is indeed the base component of Jet A and Jet A-1, the distinction lies in the formulation and additives tailored for jet engine performance. Gasoline and diesel fuel are types of fuel designed for different engine systems and do not provide the necessary properties for jet engine operation. Thus, for aviation, particularly in turbine engines, Jet A or Jet A-1 is the standard and preferred fuel choice.
