Which inefficiency arises when a Stirling engine's isothermal stages deviate?

💡 Explanation

Increased regenerator thermal losses arise because imperfect isothermal compression/expansion limits heat transfer, causing a temperature gradient; this introduces entropy. Therefore, less heat is effectively cycled rather than perfectly isothermal heat transfer.
