Effect of Engine Operating Conditions on the Vaporization of Safety Fuels
A 1932 NASA technical report on how engine operating conditions affect the vaporization of safety fuels, compiled for engineers and fuel researchers. Its pictures are strips of sequential engine-cylinder photographs in grey tones, showing fuel droplets dispersing across crankshaft-degree timelines, alongside a temperature curve comparing gasoline, hydrogenated safety fuel and diesel fuel; a designer could draw on the strict grid of frames and the radiating spray patterns as a study in sequence and dispersal.
