Increasing the Power of Internal Combustion Engines
A 1925 NASA Technical Reports Server compilation of technical memoranda on raising the output of internal combustion engines, drawn from wartime and early aviation engineering sources. Its pages are mechanical drawings of Bosch-style compressor and fuel delivery systems, mixed with a photograph of an engine bay. A designer could take from them the crisp, labelled line-drawing style of early engineering diagrams, with numbered part callouts and cutaway views of machinery.
