Performance of a High-Speed Compression-Ignition Engine Using Multiple Orifice Fuel Injection Nozzles
This is a 1930 NACA Technical Note, issued by the National Advisory Committee for Aeronautics in the United States, reporting engine tests for aircraft and engineering specialists. The pictures are plain black-and-white engineering drawings: sectioned fuel injection nozzles and valves with hatched cut faces, a cutaway engine cylinder head, and a grid chart of brake and indicated power curves. A designer could draw on their clean technical line work, hatching patterns, and labelled callout diagrams.
