摘要：

A simplified version of the Curzon-Ahlborn engine is proposed by assigning the same thermal resistance and same temperature difference at the upper and the lower isotherms of the Carnot cycle. The value of efficiency at the maximum power matches for all the three real heat engines reported by them but at the cost of marginally lower power output. The results are obtained in closed form and are easily reproducible by undergraduates using the componendo and dividendo rule and simple differentiation in contrast to considerable algebra and partial differentiation in the Curzon-Ahlborn derivation.
