With the development of social economy, facing the challenge of depletion of fossil fuel energy, countries in the world have paid close attention to the development of new energy sources in recent years attention is being focused on power engines that use new renewable energy. The Stirling engine is such a power engine. Compared with traditional combustion engines, Stirling engine has the advantages of wide fuel sources, no knocking, high thermal efficiency, low noise, low operating costs, low gas pollution, and high economy. Then, the waste heat can be used to power the Stirling engine. This waste heat will be used in aviation, aerospace, land, ocean, and other fields. The study studied the changes in power and efficiency by changing the ratio according to the dynamic configuration of the Stirling engine and by changing the thermodynamic ratio of the engine. In addition, when installing the regenerator in the Stirling engine system, the changes in output and efficiency were also studied. The results show that the dynamic parameter α is increased, the engine efficiency decreases. When the temperature ratio β increased, the engine efficiency decreased. Then, the efficiency of the Stirling engine with a regenerator was found to be higher than that of the Stirling engine without the regenerator. The results focused on dynamic configuration of the Stirling engine to utilize new renewable energy. This work provides a reliable model and theoretical guidance for improving the FPSE’s performance.
