An experimental Stirling engine driven by combustion heat of biomass was tested. It was a single acting displacer type model and had a power bellows and a displacer piston with two separate cylinders connected by a crank mechanism. The tested engine had a stainless steel bellows element as its power actuator to prevent gas leakage and to decrease friction loss at sealing. The displacer with a builtin regenerator was constructed in the form of a double cylindrical piston into which the regenerative matrix element was packed.Output performance using four types of materials were greatly influenced by the gas pressure drop caused by aerodynamic friction as the working gas passed through the pore space in the matrix element. The output power, i.e. the indicated power and net power, increased as the density of packed element rose, though the power loss also increased. This was due to the reason why the effectiveness of thermal improvement by the regenerative effect of higher density overcame the drawback of greater aerodynamic friction loss.

对生物质燃烧热驱动的斯特林发动机进行了实验研究。这是一个单作用置换型模型，有一个动力波纹管和一个置换活塞，两个单独的气缸由曲柄机构连接。试验发动机采用不锈钢波纹管作为动力执行机构，以防止气体泄漏和减少密封处的摩擦损失。内置回热器的置换器采用双圆柱活塞的形式，回热器基体单元填充在其中，工作气体通过基体单元孔隙时，气动摩擦引起的气体压降对4种材料的置换器输出性能有很大影响。输出功率（即指示功率和净功率）随封装元件密度的增加而增加，但功率损耗也随之增加。这是因为通过较高密度的再生效应的热改善的有效性克服了较大的气动摩擦损失的缺点。
