The efficiency of a Stirling engine is bounded by Carnot's theorem
The maximum theoretical efficiency of a Stirling engine, like all heat engines, is strictly bounded by Carnot's theorem.
The claim states that the efficiency of a Stirling engine is bounded by Carnot's theorem. This is a fundamental tenet of classical and finite-time thermodynamics where the Carnot limit represents the maximum possible efficiency for any heat engine operating between two thermal reservoirs. The retrieved literature repeatedly confirms the validity of Carnot's theorem and its application as an absolute upper bound for thermodynamic cycles, including Stirling engines.

Paper 0 establishes that the efficiency of minimal Carnot engines, including those based on small thermodynamic systems, is fundamentally bounded by the traditional Carnot expression.
