  1. The eigenvalues causing instability are shown in red. The period, exergetic efficiency, power output and thermal input of the cyclic steady states are also reported for comparison. CSS1: stable limit cycle of NTP model. CSS2 unstable limit cycle of NTP model. CSS1’: (unique) stable limit cycle of NTP-TL model. The origin is an unstable equilibrium point of both NTP and NTP-TL models
