本文介绍了一台α型斯特林发动机的结构和性能试验。实验在1-4巴充气压力范围内进行，以空气和氦气作为工作流体。用电加热器在加热器温度800-1000 °C的范围内以50 °C的增量加热膨胀缸的外表面。压缩气缸的外表面通过循环水冷却。加热器温度和充气压力被假定为操作参数，并且在不同的发动机转速下测量空气和氦气的发动机扭矩。发动机在437 rpm发动机转速、1000 °C的加热器温度和3.5 bar氦气充气压力下产生30.7 W的最大功率。发动机扭矩随着增压压力的增加而增加，直到3巴，然后开始下降。通过观察发动机的发动机转速范围，1000 °C热端温度和3 bar充气压力是最佳值。
This paper presents construction and performance tests of an α-type Stirling engine. Experiments were performed within the range of 1–4 bars charge pressure with air and helium as the working fluid. The outer surface of the expansion cylinder was heated with an electrical heater within the range of heater temperature 800–1000 °C with 50 °C increments. The outer surface of the compression cylinder was cooled by circulating water. Heater temperature and charge pressure were assumed as operating parameters and the engine torque was measured for different engine speeds with air and helium. The engine produced a maximum power of 30.7 W at 437 rpm engine speed, at the heater temperature of 1000 °C and 3.5 bars charge pressure with helium. Engine torque increased with the increase of charge pressure up to 3 bar then started to decrease. By looking the point of engine speed range of the engine, 1000 °C hot end temperature and 3 bar charge pressure was the optimal values.
