I am trying to understand the relationship between the NACA study and injection of steam.

The experiment was about the oxidation of CO to CO2. The process itself does not produce H20. Steam was then added externally.

Your experiment with "patrol + air" produces steam naturally.

Are you trying to suggest the combustion process is improved by introducing steam from an external source?

OK. assuming this is the case. 2cc/min at idle or at WOT? This is important because you can compare the ratio of steam production by natural combustion and steam introduced.
