Which consequence results when a Stirling engine overheats during operation?

💡 Explanation

Reduced thermodynamic efficiency occurs because overheating increases irreversible processes due to greater temperature differences during heat transfer; the Stirling cycle deviates from ideal isothermal conditions, therefore reducing efficiency, rather than the other options which would require different conditions or failures.
