The Fundamental Principles of High-speed Semi-diesel Engines. Part I: a General Discussion of the Subject of Fuel Injection in Diesel Engines and Detailed Descriptions of Many Types of Injection Nozzles
A 1926 British Aeronautical Research Committee technical memorandum on fuel injection for high-speed diesel engines, issued for engineers and designers of engine components. Its three pages of line drawings show cross-sections of many injection nozzle designs, each labelled with a maker's name and a figure number. A designer could take from them the compact, layered mechanical forms of early nozzle bodies, valves and spring housings as a clear model for technical line diagrams.
