Ignition points and combustion reactions in Diesel engines. Part II
This is a 1928 NACA Technical Memorandum, No. 484, part two of a study of ignition points and combustion reactions in Diesel engines, issued by the NASA Technical Reports Server collection. Its pictures are plain engineering line charts and a section drawing: curves of ignition temperature against pressure for shale oil, coal tar oil, lignite tar and paraffin-type fuel mixtures, plus a cutaway of the ignition point test apparatus. A designer could take from them the restrained, grid-based chart style of early technical reports, with fine black lines, labelled axes and small numeric scales.
