Why do airplanes have to burn kerosene? What is the difference between gasoline and diesel?
The reason why airplanes do not use gasoline and diesel is not because they are not compatible, but because the advantages of kerosene are more obvious!
A large part of the reason why gasoline is used in cars is that it is highly volatile. This fuel is fine on the ground, but if it is put on an airplane, especially a supersonic fighter jet, once the temperature of the shell rises, the safety will be greatly reduced.
Diesel is safer than gasoline, but it has a very high ignition point, and once equipped, the turbine engines commonly used in aircraft can be inadequate.
It is not an easy task to make diesel fuel effectively burn in a high-speed engine, from the perspective of technology and cost at this stage.
The reason why kerosene is used in the aircraft is because its volatility is lower than that of gasoline and its ignition point is lower than that of diesel.
In addition, kerosene has high density and strong frost resistance, so even in the cold zone, the aircraft can still maintain good mobility.
What's more, it requires less oxygen than gasoline and diesel, which can better adapt to the anoxic environment when flying in the stratosphere. Therefore, in the choice of fuel, the aircraft will naturally choose kerosene!
