Evaluation of scavenging in two-stroke-cycle engines
This is a 1934 NACA technical memorandum, No. 732, issued by a National Advisory Committee for Aeronautics office and concerned with scavenging in two-stroke engines. Its charts and line drawings plot scavenging pressure, pump efficiency and port geometry for engineers working on crankcase and charging pumps. A designer might take from it the clean, grid-based technical plotting style and the schematic cutaway drawings of scavenging ports.
