本論文探討雙動式四氣缸史特靈引擎之原型機設計與實驗結果分析，透過實驗結果結合理論模式結果來觀察理論模式與實驗是否吻合。因此，以設計雙動式四氣缸史特靈引擎之原型機以進行性能量測及驗證擺軛式傳動機構為目標。本論文使用之理論模式為針對單腔室所做的分析，單腔室又分為膨脹室、加熱室、再生室、冷卻室與壓縮室，探討子腔室內壓力、體積、溫度與質量變化之結果，考慮工作流體所造成之壓力損失並計算引擎單腔室之功率與熱效率。而原型機的設計主要目標為設計複雜度較低的機構來避免過多的摩擦力及引擎漏氣的可能，以提高原型機的可行性，進而得到實驗結果。最後以實驗結果為準來修正理論模型，並透過理論模式提供原型機設計性能增進可能之建議。根據實驗結果，以四氣缸等起始壓力填充10bar之氦氣、加熱溫度1000 K、冷卻溫度300 K之條件下於轉速750 rpm時軸功率可達25.9 W，同時熱效率最大可達7.06%。

This thesis discusses the prototype design and experimental results of a double-action four-cylinder Stirling engine, and observes whether the theoretical model and experiment results fit together or not. The objective is to design a prototype of a double-action four-cylinder Stirling engine for performance measurement and verification of the Wobble yoke mechanism. The theoretical model of this paper is used to analyze single chamber, which is divided into expansion chamber, heating chamber, regeneration chamber, cooling chamber and compression chamber. The main objective of prototyping is to design mechanisms with low complexity to avoid excessive friction loss and the possibility of gas leakage from engine, so as to improve the feasibility of prototyping and obtain experimental results. Finally, the theoretical model is revised based on the experimental results, and the theoretical model will provide suggestions for improving the design for better performance. According to the results of the experiment, the shaft power can reach 25.9 W at 750 rpm under the initial pressure of 10 bar of helium gas, heating temperature 1000 K and cooling temperature 300 K. In this case, the thermal efficiency reaches 7.06%.
