Water Cooling

["Buchholz, Steven" <Steven.Buchholz@kla-tencor.com>]

It seems like we are talking about two situations, external use of water to
help cool the intake charge and water injection into the intake charge
itself.  For the first situation I doubt that there is a real need to create
a fine mist of water as what you want to do is take advantage of the cooling
effects of the water evaporating away from the intercooler.  AAMOF, it seems
to me that if you had something that already created a vapor it would be
relatively useless as the liquid water had already absorbed the heat of
vaporization from somewhere else before it even got to the intercooler.  I
am less clear on the water injection into the intake charge, but it sure
seems to me that even there you want a fine spray of liquid water in the
intake so that it can vaporize in the cylinder ...
