Previous research has found that engine speed reduction improves thermal efficiency. However, it was theorized that the regenerator heat storage capacity is insufficient because there are limitations to the improvement in thermal efficiency that can be achieved by engine speed reduction. Therefore, the purpose of this study is to improve the thermal efficiency and to confirm engine speed change when the thermal efficiency is maximized through increased regenerator heat storage capacity in Stirling engines. To this end, engine performance testing was performed using an experimental Stirling engine and adding heat storage material to the regenerator. The results showed no confirmed engine speed change, but did confirm improved thermal efficiency. Furthermore, it was shown that the thermal conductivity of the heat storage material used in the regenerator significantly affects thermal efficiency.}, pages = {10--15}, title = {スターリングエンジンのディスプレーサピストン表面に担持された蓄熱材が熱効率に及ぼす影響}, year = {2020} }
