    Abstract: 本篇論文主要探討史特靈引擎的發展與熱力循環的實驗,史特靈引擎有許多優點,例如史特靈引擎可以使用不同種類的熱源,如太陽能、地熱,生質能、核能和工業廢熱,而內燃機只能使用單一熱源。史特靈引擎使用單相工作流體,使其內部壓力變化接近設計壓力,與內燃機比較其機械結構亦相對簡單,危險度也較低。目前世界相關國家正積極發展史特靈引擎的應用,如聚焦型太陽能史特靈發電系統、家庭式與工業用的史特靈引擎。
    實驗主要針對本研究室先前製作的 Gamma 型態史特靈引擎進行熱力循環測試,輸入功率為 250W、350W 與 500W,利用伺服馬達測量引擎穩態時之轉速與汽缸體積變化,汽缸壓力則由壓力感測器量測,並配合理論模式分析不同輸入功率下之壓力體積變化圖。
    In this study, focuses on the introduction of Stirling engine development and thermal cycle test. Stirling engine has many advantages, such as Stirling engines can run directly on any available heat source, not just one produced by combustion, so they can run on heat from solar, geothermal, biological, nuclear sources or waste heat from industrial processes. The engine mechanisms are in some ways simpler than other reciprocating engine types. A Stirling engine uses a single-phase working fluid which maintains an internal pressure close to the design pressure, and thus for a properly designed system the risk of explosion is low. Stirling engine has been developed rapidly worldwide toward its applications, like solar dish Stirling system, combined heat and power tirling engine.
    Thermal cycle test was conducted by the Gamma type Stirling engine fabricated previously in the group. Using servo motor apparatus, Engine speed and volume change of the cylinder were measured under the input power of 250W, 350W and 500W. The pressure variations of the cylinder were determined by a pressure transducer. The experimental P-V diagram was compared with the theoretical model to evaluate the performance of the engine.
    Experimental results showed that pressure of the cylinder increased insignificantly when the input power was increased. Comparing to the theorem, the test engine showed alow pressure distribution and a low thermal efficiency. In addition to the leakage of the system, the friction between crank shafts and connecting rods may be the key issues leads to a poor engine performance.
