Performance of a Fuel-Injection Spark-Ignition Engine Using a Hydrogenated Safety Fuel
This is a 1934 NASA technical report on a spark-ignition engine test, using fuel injection with a hydrogenated safety fuel, written for aeronautical engineers. The pictures are engineering line charts, cutaway drawings and labelled plans of an injection valve and combustion chamber, rendered in plain black linework on cream paper, offering a designer clean technical diagrams and graph grids to borrow for schematic or infographic layouts.
