Discharge characteristics of a double injection-valve single-pump injection system
This is a 1937 NASA technical report on fuel discharge characteristics of a double injection-valve, single-pump injection system, prepared for engineers studying diesel fuel injection. The pictures are dense rows of fuel discharge curves plotted against pump rotation in degrees, with pressure and injection-weight values annotated on each graph. A designer might take from them the rhythmic stacking of small line graphs with dashed timing markers and labelled numeric values, a clean technical chart layout.
