Thermostatics of Carnot engines has been extended by more recent research based on endo-reversible model. Our model assumes exo-reversibility but endo-irreversibility to determine new upper-bound to thermomechanical conversion. We propose a functional expression of entropy production related to cycle transformation durations. This approach analyses the energy, entropy and power consequences. We introduce a new concept of entropy production actions that results in three sequential optimums: maximum energy related to transformation durations, maximum energy associated with equipartition of entropy actions, optimal power for given cycle period.
