As an expert in the field of aviation fuels, I can explain why kerosene is the preferred choice for jet engines over other fuels like gasoline.
Firstly, kerosene has a higher energy content per unit volume compared to gasoline. This is crucial for long-haul flights where fuel efficiency is key. The higher energy density of kerosene allows an aircraft to carry less fuel for the same energy output, reducing the overall weight of the aircraft and improving its fuel efficiency.
Secondly, the combustion characteristics of kerosene are more suitable for jet engines. Jet engines operate at very high temperatures and pressures, and kerosene has a higher flash point and autoignition temperature than gasoline. This means that kerosene is less likely to ignite prematurely, which is a critical safety consideration in the operation of jet engines.
Thirdly, kerosene is more stable and less volatile than gasoline. This stability is important for the storage and handling of the fuel, as it reduces the risk of evaporation and the potential for explosive vapors, which is a significant safety hazard.
Another important factor is the lubricity of the fuel. Kerosene has better lubricating properties than gasoline, which is beneficial for the moving parts of the engine. Good lubrication is essential to reduce wear and extend the life of the engine components.
Additionally, kerosene is more widely available and has a more established infrastructure for distribution and storage compared to other types of aviation fuels. This makes it a more practical choice for the aviation industry.
Lastly, the use of kerosene in jet engines is also supported by regulatory standards and industry practices. There are strict regulations governing the quality and composition of aviation fuels to ensure safety and performance. Kerosene meets these standards and is widely accepted by the aviation community.
In summary, kerosene is used as jet fuel due to its higher energy content, suitable combustion characteristics, stability, better lubricity, availability, and adherence to regulatory standards.

The very high temperatures of jet engines cause gasoline to be a poor fuel because it tends to burn too fast. Kerosene, which is routinely called "Fuel OIL" some places, avoids pre-ignition problems (and some safety hazards) just like higher-octane gas avoids spark-plug knocking.
