When a diesel engine experiences pre-ignition, which mechanism rapidly deteriorates piston integrity?

💡 Explanation

Detonation-induced thermal shock creates localized high pressures and temperatures which rapidly exceed the piston material's yield strength because uncontrolled combustion creates shockwaves. Therefore, the piston suffers fatigue failure, rather than gradual wear from oil breakdown or other factors.
