Flame Movement and Pressure Development in an Engine Cylinder
This NACA-era technical report from 1932, issued through NASA's Technical Reports Server, presents laboratory findings on how flame spreads and pressure builds inside an engine cylinder, written for engine researchers. Its pictures are plain engineering graphs of window number, inflammation time and cylinder pressure against spark timing, air-fuel ratio and crank angle, with one streaked time-exposure photograph of a flame front; a designer might borrow their restrained grid layouts, labelled curves and monochrome line-chart clarity.
