Development of a Stirling Engine for Farm-use with Biomass Resources.

研究了一种具有多种燃料选择、排气清洁、噪音小、振动小等优点的斯特林发动机。这项研究的目的是开发农场可用的斯特林发动机，这种发动机简单且免维护。如何防止工作气体泄漏，减少机械摩擦损失是斯特林发动机研制过程中的根本技术问题。试制的斯特林发动机为单作用置换式，配有牌号为“波纹管”的翻领式波纹管动力活塞和内置回热器的排量活塞。考察了翻盖式波纹管在常温和加热条件下的密封性能和机械摩擦特性。试验结果表明，采用翻领式“波纹膜片”，防止了气体泄漏，降低了机械摩擦损失。在400℃(ﾟC)的燃气温度下，发动机的循环功达到19(J/周期)。与以前试制的发动机相比，输出功率性能得到了改善。

A Stirling engine which has a number of merits such as a wide choice of various fuels, clean exhaust, small noise, low vibration, etc.has been studied. The aim of this study is the development of farm usable Stirling engines which are simple and free from maintenance. The fundamental technical problems in the development of a Stirling engine are how to provent the working gas leakage and to reduce the mechanical friction loss.The trial-made Stirling engine was a single acting displacer type and had a lapel type bellows power piston which is named "bellowsphragm" as a brand name and a displacement piston built-in regenerator. The lapel type bellows seal performances and the characteristics of mechanical friction were examined under the normal temperature and heating conditions. The testing results show that the gas leakage was prevented and the mechanical friction loss was reduced by using the lapel type "bellowsphragm". The cycle work was gained of 19 (J/Cycle) at the gas temperature of 400 (ﾟC) on the engine operation. The output power performances were improved in comparison with the previous trial-made engine.
