Relation of Hydrogen and Methane to Carbon Monoxide in Exhaust Gases from Internal-Combustion Engines
A 1935 NACA technical report on exhaust gas composition from internal-combustion engines, issued by the NASA Technical Reports Server collection for engineers and fuel researchers. Its pictures are plain engineering charts and photographs: a scatter plot of exhaust carbon monoxide readings against fuel type with a fitted line, and a photograph of a laboratory gas-analysis apparatus, useful to a designer for spare, technical graph and instrument imagery.
