Ignition and Flame Development in the Case of Diesel Fuel Injection
A 1936 technical report on diesel fuel ignition and flame development, published through the NASA Technical Reports Server and aimed at engine researchers. Its pictures are grainy high-speed photographs of fuel spray and flame frames in a prechamber engine, with numbered sequence strips and graphs of pressure and temperature traces. A designer might borrow the rhythm of sequential frames, the dark-to-bright tonal range of the flame glow, and the dense ruled chart lines.
