Fuel Vaporization and Its Effect on Combustion in a High-Speed Compression-Ignition Engine
A 1933 technical report on fuel vaporization and combustion in high-speed compression-ignition (diesel-type) engines, issued through the NASA Technical Reports Server and aimed at engine researchers. Its pictures are plates of photographic sequences: rows of small circular frames showing spray or flame at successive timing angles, arranged as horizontal bands on dark grey and black fields with a degree scale beneath. A designer might take the strict grid of repeating circles and the stepped, staggered rhythm of the bands as a graphic pattern.
