摘要

本研究為設計一Gamma型態史特靈引擎，製造並測試。在一大氣壓下，工作流體為空氣下使用交流電源供應器加熱測試。分別輸入200 W、250 W以及300 W，實際輸入熱源分別為156.3 W、187.6 W以及223.2 W。測試不同的輸入熱源，引擎在不同轉速下的負載扭矩、輸出軸功和制動熱效率。並比較單動力汽缸與雙動力汽缸之性能。
在輸入熱源為223.2 W下，單動力汽缸在轉速為405 rpm時有最大扭矩為0.13 Nm。在轉速為456 rpm時有最大輸出軸功5.73 W，最大制動熱效率2.57 %。雙動力汽缸在轉速為412 rpm時有最大扭矩為0.15 Nm。在轉速412 rpm時有最大輸出軸功6.47 W，最大制動熱效率2.9 %。

In this investigation, a gamma-configuration Stirling engine are designed and constructed. The single and twin power cylinder engines are tested with air at atmospheric pressure by using a electric heater as a heat source. The engine is tested with heater input of 156.3W, 187.6W, and 223.2W. Variations of engine torque, shaft power and brake thermal efficiency with engine speed and engine performance at various heat inputs are presented.
The results indicate that at the maximum heater input of 223.2 W, the heater temperature for single power cylinder and twin power cylinder are 612℃ and 574℃. The two engines produce a maximum torque of 0.13 Nm at 405 rpm and 0.15 Nm at 412 rpm; a maximum shaft power of 5.73 W at 456 rpm and 6.47 W at 412 rpm; a maximum brake thermal efficiency of 2.57 % at 456 rpm and 2.9 % at 412 rpm, respectively.
