The Diesel as a Vehicle Engine
This is a 1928 NACA Technical Memorandum, The Diesel as a Vehicle Engine, issued by the National Advisory Committee for Aeronautics for engineers studying diesel engine performance. The pages are engineering graphs of pressure, power, fuel consumption and temperature plotted against injection pressure, compression ratio and rotational speed. For a designer the value lies in the clean plotting conventions: dense grid lines, labelled curve families and dashed reference markers that suggest a precise technical diagram style.
