← ScienceWhich outcome results when thermal mass increases excessively within a Stirling engine?
A)Isothermal expansion efficiency diminishes appreciably✓
B)Internal lubricant viscosity is significantly lessened
C)Heat exchanger mechanical stress increases rapidly
D)Regenerator matrix pore size decreases greatly
💡 Explanation
Excessive thermal mass in a Stirling engine leads to decreased *isothermal* behavior during expansion *because* the cycle approaches adiabatic conditions, thus reducing ideal efficiency. Therefore, efficiency diminishes, rather than internal stresses increasing, underperforming because Stirling engines are designed with nearly isothermal changes.
