摘要：

A model of an endoreversible Carnot engine is considered where the piston moves with a constant speed u. Expressions for the cycle time tau for the four branches, as well as output power, P-W, are derived and the optimized root for maximum power is obtained in closed form. Our results are discussed in terms of the isothermal expansion ratio V-2* and temperature ratio a in a manner accessible to students.
