Some Factors Affecting the Reproducibility of Penetration and the Cut-Off of Oil Sprays for Fuel-injection Engines
This 1928 NASA technical report, issued by the National Advisory Committee for Aeronautics, studies how oil sprays from fuel-injection valves penetrate into the combustion chamber of an engine. The plates include penetration-versus-time curves plotted against injection timing, and high-speed photographs of spray plumes under different injection pressures and chamber conditions. A designer could draw on the sweeping curves and the dense, feathered spray shapes for abstract motion or fluid graphics.
