Which constraint affects Carnot engine efficiency under non-ideal operation?

💡 Explanation

The Carnot cycle achieves maximum theoretical efficiency via reversible processes; however, in real engines, irreversible heat transfer increases entropy, because this diverges from isothermal conditions, therefore reducing efficiency rather than work output.
