Influence of fuel-oil temperature on the combustion in a prechamber compression-ignition engine
This is a 1936 NACA technical note from the NASA Technical Reports Server, written for aeronautical engineers and published in the United States, on how fuel-oil temperature affects combustion in a prechamber compression-ignition engine. The pictures are plain black-and-white engineering drawings and photographs: a sectioned fuel-injection valve with its scale, a schematic fuel system, a graph of effective fuel burned against crank angle, and a photo of a single-cylinder test engine with its gauges and equipment. A designer might take from them the spare, labelled diagram style of mid-century technical reports, with clear hatching for cut solids and simple line graphs.
