摘要

在這篇論文?堙A設計製造出一具小型分置式史特靈引擎。使用空氣作為工作流體，填充壓力為一個大氣壓力，利用瓦斯燃燒爐為其熱源來測試這具引擎的性能。這具史特靈引擎的性能以不同的瓦斯流量作為熱輸入，以測量各種轉速下引擎的轉矩、軸功。

結果顯示小型分置式引擎在最高瓦斯流量0.214g/sec的實際熱輸入下，引擎在每分鐘100.75轉時可產生的最高扭矩為0.825N.m，在208轉時產生的最高軸功為15.74W。減少機械摩擦損失、加強密封設計是提升引擎性能的重要關鍵。

In this paper, a small gamma type Stirling engine is designed and constructed. The engine performance is tested with air at atmospheric pressure by using a fuel gas burner as a heat source. The engine is tested with various fuel gas flows to be heat inputs. Variations of engine torque, shaft power at various fuel gas flows with engine speed are presented.

The results indicate that, for a small gamma type Stirling engine, at a maximum fuel gas flow of 0.214g/sec, the engine produces a maximum torque of 0.825N.m at 100.75rpm, a maximum shaft power of 15.74W at 208rpm. The important key to promote the engine performance is to reduce the mechanical friction loss and strengthen the seal design.
