Which outcome occurs when reciprocating engine cylinder head temperature significantly exceeds design limits during operation at maximum load?

💡 Explanation

When cylinder head temperature exceeds design limits, hot spots form, initiating uncontrolled auto-ignition before the spark plug fires, which results in detonation due to pressure wave collision. Therefore, pre-ignition and detonation will occur, rather than seal failure, oil thickening or bearing seizure, which need different dominating mechanisms.
