On the Analysis of Indicator Diagram
Journal of the Society of Mechanical Engineers, 1949 燃焼室に窓を作つて, シリンダ内の火炎を高速度寫眞で撮影すれば, シリンダ内の燃焼状況を知ることができるが, 実用シリンダの研究を行うには, この方法はほとんど不可能である.そこで, 簡單にとれるインジケータ線図から, 幾分でもこれに代り得る方法がないものだろうかと考えて, 本報告の解析方法を考えた.本報告には, 燃焼質量割合および同容積割合と, これらを使つてサイクル各点における既燃焼ガス, 未燃焼ガスの温度分布, 圧力等を算出する方法を述べ, それらから得た二三の結果について論じた.
