Considerations of Air Flow in Combustion Chambers of High-Speed Compression-Ignition Engines
This is a 1932 NACA technical note, published by the National Advisory Committee for Aeronautics in the United States, that reports research on air motion inside combustion chambers of high-speed compression-ignition engines for engineers and researchers. The four pictures are engineering drawings, a photograph of a copper gasket, performance curves and a cylinder-head sketch with a photographed carbon deposit. For designers they offer clean, technical line diagrams with fine hatching, labelled leader lines and plain graph axes that suggest a restrained, schematic visual vocabulary.
