低温度差スターリングエンジン高出力化の検討

抄録

Since the Industrial Revolution, the mankind has achieved astonishing technological innovation and economic development. Recently, the environmental pollution and global warming caused by a large amount of consumption of fossil fuels have become apparent. From such a background the Sustainable Development Goals (SDGs), which include climate change measures, were adopted at the UN Summit in 2015. On the other hand, Japan's energy self-sufficiency rate is 11.8%, which is low among developed countries, and Japan is dependent on imports of most fossil fuels from other countries. Besides the Stirling engines is not necessarily require the combustion of fossil fuels and is therefore low polluting. From this point, the Stirling engines attracts, attention in recent years. But one of the problems preventing the practical use of the Stirling engine is that it is more difficult to miniaturize than a conventional internal combustion engine. Another disadvantage is that the output response is poor. In this study, we focused on the Stirling engine as an engine that uses renewable energy and designed and manufactured a Stirling engine that can be operated even when snow or ice is used as the low-temperature heat source. And, we use a room temperature as the high-temperature heat source. The aim of this research is to make effective use of low-temperature heat sources that have not been used until now.
