NACA study 531

I guess the NACA paper is focused on oxidantion of CO in a environment with steam.

Putting this study in practice in an ICE, CO percentage will be less but HC emissions is higher.

All the air in the cylinder is at the same temperature on the tests they do.
Only the water vapor level is different. So water displaces 02 in test cylinder. But flame moves faster. Something too ponder?

One thing I've found with steam injection with carbed engine is that the HC's go down. I tested it with 4gas analyzer. Steam helps vaporize fuel on its way too combustion chamber. I don't have the 4gas analyzer now too show you that.
