Application of Carnot cycle in Heat Engine and Efficiency Improvement of Carnot Heat Engine

It has been two hundred years since the Carnot cycle was proposed and used to analyze the working process of a heat engine in 1824 by the French engineer Nicolas-Lonard Sadi Carnot. Similarly, the Carnot cycle has been improved and practiced for the same time. Why have the results of Carnot's work been so highly regarded and so widely used for over a century? Moreover, how can people improve on Carnot's research based on the ideal state required by the Carnot cycle more efficiently? This paper will describe the basic principles of the Carnot cycle and how it has been applied to heat engines. Based on recent research, scientists have come up with ideas and methods of improvement. Based on previous experience and research, this thesis will provide a certain summary of what is known about the Carnot cycle and provide some ideas on further improving the direction of Carnot heat engine efficiency afterwards.
