摘　　要：基于有限时间热力学理论,建立内可逆等温加热修正Atkinson循环模型,导出循环功率、效率的解析式,分析预膨胀比、最大温比和传热损失对循环性能的影响,并将等温加热修正Atkinson循环与传统Atkinson循环进行比较。结果显示,在同样的循环参数条件下,等温加热修正Atkinson循环的性能优于传统Atkinson循环;功率与压缩比的曲线、效率与压缩比的曲线均呈类抛物线,功率与效率的曲线呈扭叶形;循环的性能随着循环预胀比和最大温比的增加而提升。Based on the finite time thermodynamic theory,an endoreversible isothermal heating modified Atkinson cycle is established,the cycle efficiency and power analytical expressions are derived.The effects of pre-expansion ratio,the maximum temperature ratio and heat transfer loss on cycle performance are analyzed,and the performance of the endoreversible isothermal heating modified Atkinson cycle is compared with that of the endoreversible traditional Atkinson cycle.The results show that,under the same cycle parameter condition,the performance of the isothermal heating modified Atkinson cycle is better than that of the traditional Atkinson cycle.The curves of power versus compression ratio and efficiency versus compression ratio are all parabolic-like ones,and the curve of power versus efficiency is loop-shaped one.The cycle performance increases with the increases of the cycle pre-expansion ratio and the maximum temperature ratio.
