Popis:	One famous paper in this field [Am. J. Phys. 43, 22 (1975)] unveiled the efficiency at maximum power (EMP) of the endo-reversible Carnot heat engine, now known as the Curzon-Ahlborn (CA) engine, making a pioneering contribution to the genesis of finite-time thermodynamics. Despite its significance, similar findings have surfaced throughout history; for instance, the Yvon engine proposed by J. Yvon in 1955 shares the exact same EMP as the CA engine. This study extends Yvon's original approach to reanalyze the finite-time optimization of the CA engine. Our investigation not only bridges the gap between the Yvon engine and the CA engine but also serves as a suitable example for teaching undergraduate thermodynamics and engineering thermodynamics, given its concise and easy-to-understand derivation. Comment: 4 pages, 2 figures. Comments are welcome
