How does the small amount of humidified air that is introduced into the
intake air stream remove carbon? If the air is at ambient air temp, how
much water vapor can it pick up in the short amount of time it passes
throught the alcohol/water mixture and to the intake manifold?
If you live in a desert, where the air is naturally dry, is carbon build-up
more of a problem? Conversely, if water vapor/humidity helps prevent/remove
carbon buildup, are the engines on Florida cars naturally low on carbon
buildup?
