In reading the latest issue of Sport Compact Car, part of the article on the Mazdaspeed three grabbed my attention. It seems the extremely high pressure of Mazda's DISI fuel system causes instant atomization of the fuel that absorbs 50-70 degrees from the combustion chamber. This allows for considerable advantages as both an anti-detonation measure and in allowing more oxygen to be stuffed in. So my question is this: would this work for water injection as well? Obviously, water injection does these things already. Would it work better at higher pressure levels?
