研究了具有有限化学势差的自主发动机的最大效率。我们证明，如果没有特定类型的奇点，自治引擎就不能达到卡诺效率。这种奇点有两种实现方式：单粒子输运和热力学极限。我们证明了这两种方式实际上都导致了具体设置中的卡诺效率。我们的结果清楚地表明，奇异性对自主发动机的最大效率起着至关重要的作用。
The maximum efficiency of autonomous engines with a finite chemical potential difference is investigated. We show that, without a particular type of singularity, autonomous engines cannot attain the Carnot efficiency. This singularity is realized in two ways: single particle transports and the thermodynamic limit. We demonstrate that both of these ways actually lead to the Carnot efficiency in concrete setups. Our results clearly illustrate that the singularity plays a crucial role in the maximum efficiency of autonomous engines.
