Effect of air-entry angle on performance of a 2-stroke-cycle compression-ignition engine
A 1937 NACA technical note reporting tests of a two-stroke compression-ignition engine, published by NASA's Technical Reports Server from the NACA series, written for engineers studying how intake air-entry angle affects power and fuel use. Its four pictures are dense engineering graphs of brake mean effective pressure, fuel consumption and supercharging pressure, plus a line plot and a schematic of the surge tank, exhaust valve, guide vanes and blower, which a designer might borrow for technical chart layouts and vintage schematic linework.
