Default NACA study 531

Is seems that water can speed up the CO oxidation.

I have heard this before but never seen a study of it. It is a very good find.

CO is a power robber, it only produces 1/3 of heat energy compared to CO2.

The problem is they used super heated steam for testing. :wink:

Ah, I see. I will read it up again, very interesting.

Don't read it again that's normal protocol for testing. Change protocol changes results.
There are other types of "steam" other than saturated, dry, superheated.

So CO2 can burn? Or does CO interfere more than CO2 in combustion?

Better be late than never.

CO2 is fully oxidised, no more bonds to attract more oxygen.
CO is the result of lack of oxygen. You can consider it is half burnt wood, giving out half of the heat energy and gets throw out.

In the case of CO, it only gives out 1/3 of the heat energy.

Combustion process releases electrons. In my opinion the right amount and condition of water conducts the flame front at greater speeds.

Wow, a great deal of readings to night. Thanks for the findings.

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.
