What is a potential consequence of using a mixture of aviation gasoline and jet fuel in a reciprocating airplane engine?

• A. The engine may improve performance
• B. There are no significant effects
• C. The engine may be damaged or destroyed
• D. The fuel efficiency will increase

Answer: (C)

Using a mixture of aviation gasoline and jet fuel in a reciprocating airplane engine can lead to severe consequences, including potential damage or destruction of the engine. Reciprocating engines are specifically designed to operate on aviation gasoline, which has a different composition, including a higher octane rating, than jet fuel. Jet fuel, on the other hand, is a kerosene-based fuel that lacks certain characteristics essential for the proper operation of a reciprocating engine, such as the necessary lubrication properties. When a mixture of these fuels is introduced into a reciprocating engine, the combustion process can become inefficient or even lead to pre-ignition and detonation, which can cause extreme pressure and heat within the engine. This results in potential damage to critical engine components, such as pistons, cylinders, and valves. Consequently, the integrity of the engine can be compromised, leading to catastrophic failure. Other options do not accurately describe the effects of mixing these fuels. It’s essential for aviation operations that only the appropriate fuel type is utilized for each engine design to ensure safety and effective performance.
