Abstract

In this work we analyze the stability of a non-endoreversible Curzon-Ahlborn engine, working in an ecological regime, taking into account the engine implicit time delays. When it is compared the system's dynamic stability with its thermodynamic properties (efficiency and power output), we find that the temperature ratio τ = T₂ /T₁ (being T₁ > T₂ > T the temperatures of the external thermal reservoirs) represents a trade-off between stability and energetic properties. When we take the non endoreversibe case τ, can increase up to R (where R is the non edonreversible parameter). Finally, we demostrated that the total time delay does not destabilize the system steady state. It does not seem to play a role in the dynamic thermodynamic property trade-off.
