What can detonation lead to if not corrected?

Detonation in an aircraft engine refers to the uncontrolled explosion of the fuel-air mixture in the combustion chamber. This phenomenon can lead to significantly increased pressure and temperature that the engine components, particularly the pistons, are not designed to withstand.

If detonation occurs and is not corrected, it can result in severe damage to the pistons. The high-pressure waves can cause the piston to deform or even fracture, which can lead to catastrophic engine failure. This kind of damage is serious and can lead to a complete loss of engine power, posing a significant risk to flight safety.

Understanding the implications of detonation is crucial for pilots, as it emphasizes the need for appropriate fuel selection, mixture settings, and maintaining proper engine temperatures to prevent such occurrences.
