This experiment designs and investigates the application of a γ Stirling engine in gravity energy storage. The displacer of a dual-cylinder γ Stirling engine is optimized to integrate a regenerative function, effectively improving heat exchange efficiency. By connecting a gas pressure transducer and a high-speed camera, real-time pressure and volume changes during engine operation are captured, and instantaneous p-V diagrams are plotted. Experimental results indicate that under a temperature difference of 178 K, the Stirling engine achieves a rotational speed of 126 rpm, a mechanical output power of 0.6 W, and a conversion efficiency of 0.17%. Although the efficiency is relatively low, it highlights the coupling of a Stirling engine with gravity energy storage, offering substantial educational value for demonstrating thermodynamic principles and providing a novel approach to addressing challenges in renewable energy grid integration.
