NACA study 531

[Richard L]

Had time to glance through the document today. It is an interesting read indeed.

I can imagine how this can be translated into the internal combustion engine dynamics.

Experiment shown present of water vapor aided frame front propagation of CO+O2 to CO2 conversion. During a normal combustion cycle starting from the onset of spark, the production of water vapor is continuous from the product of air and fuel. I can see a distinct advantage if there are presence of excess oxygen. In a fuel rich condition in a oxygen limited closed chamber, most of the CO just exits the engine via the exhaust pipe.

This is just a brief conclusion from reading the article briefly. Please chime in if you view it differently.
