In this paper, we have studied electrically charged black holes in a new model of nonlinear electrodynamics introduced by Kruglov in Mod. Phys. Lett. A 32, 1750201 (2017). There are two parameters for the theory and the black hole could have up to two horizons. Thermodynamics is studied in the extended phase space where the pressure is proportional to the cosmological constant. First law and the Smarr formula are derived. There are phase transitions similar to the Van der Waals liquid-gas phase transitions. Black hole is also studied as a heat engine and we have discussed how the parameters in the nonlinear electrodynamics theory affect the efficiency of the heat engine.

在本文中，我们研究了 Kruglov 在国防部。物理。莱特。一种 32, 1750201 (2017)。该理论有两个参数，黑洞最多可以有两个视界。在扩展相空间中研究热力学，其中压力与宇宙学常数成正比。推导出第一定律和 Smarr 公式。存在类似于范德华液-气相变的相变。黑洞也作为热机进行研究，我们已经讨论了非线性电动力学理论中的参数如何影响热机的效率。
