A general property of non-endoreversible thermal cycles

In this work it is shown that a general property of endoreversible Curzon-A hlborn-Novikov (CAN) cycles previously demonstrated can be extended for non -endoreversible CAN-cycles. This general property is based on the fact that at the so-called maximum ecological regime the efficiency is the average o f the Carnot and the maximum-power efficiencies, and that in such a regime the power output is 75% of the maximum power of the CAN-cycle and the entro py produced is only 25% of that produced in the maximum power point. This p roperty is independent of the heat transfer law.
