Effect of oxygen on the ignition of liquid fuels
A 1929 technical report from the NASA Technical Reports Server, a digitised archive record, presenting experimental findings on how oxygen concentration affects the ignition of liquid fuels such as gas oil and benzine. The pictures are line graphs of flame height and ignition lag against combustion chamber temperature, plus a schematic of the laboratory apparatus. A designer might take from them the dense family of curved, labelled lines and the clean engineering diagram style with lettered parts.
