Why Do Aircraft Engines Use Kerosene?
1 Answers
Aircraft engines do not use gasoline or diesel because gasoline is a volatile substance with a low flash point and rapid combustion. Below is an introduction to why aircraft engines avoid gasoline and diesel: 1. Kerosene has a higher specific gravity, allowing it to store more heat and weight, and it is not as volatile as gasoline. Since aircraft have limited fuel-carrying capacity, using kerosene is more economical and durable. Additionally, kerosene is safer than gasoline and can be better atomized in turbine engines, ensuring more stable combustion. Considering these factors, aircraft use kerosene as fuel. 2. During high-speed flight, aircraft inevitably generate heat through friction with the air, which would cause gasoline to evaporate more quickly. A mid-flight fuel shortage would have severe consequences. Diesel, on the other hand, is too viscous. While it can be used in compression-ignition engine aircraft, it is not easily atomized and sprayed in the more common turbine engines, making combustion more difficult.
