Scavenging a Piston-ported Two-stroke Cylinder
This is a 1938 NACA Technical Note, issued by the National Advisory Committee for Aeronautics, reporting experimental work on scavenging in a piston-ported two-stroke engine cylinder. The pictures are black-and-white photographs and mechanical drawings of engine parts, including cylinder heads, a complete engine assembly, and charts of scavenge pressure against exhaust and intake settings. A designer might borrow the clean technical plate layout, the precise line-drawn sections, and the grid-paper graph styling.
