Electrical characteristics of spark generators for automotive ignition
This is a technical report on electrical characteristics of spark generators for automotive ignition, issued in 1927 and catalogued by NASA's Technical Reports Server, apparently written for engineers rather than a general readership. The four pictured graphs plot conductance in micromhos on the horizontal axis against a vertical quantity with three labelled curves A, B and C, each falling steeply then levelling off. A designer might take from them only the clean monochrome plotting style, the labelled curve families and the sweeping decay shape, useful as a source for scientific chart layouts.
