Water Injection (Was: Re: Wide Ratio O2)

[Espen Hilde]

I think water injection must be as accurate as the fuel injection.Its no
use ,if you
have a precise measured quantity of fuel and spark and then just dump in
some 
water.
Maybe its possible to use a efi system with staggered injectors, and use
the 
second injector set, to deliwer water?
Will the injectors stand the water?Is it possible to use a standard high
pressure 
fuelpump? Maybe ad some anti corrosion stuff?
By adding water ,the carbon deposits in the combustion camber is cleaned
away.
A "dump" system is good for cleaning up the carbon hot spots,that can
create 
pre-ignition.
By adding water Its possible to have higher top cyl.pressure without
detonation, than with just 
adding  fuel.
Just some brain storming:Dual fuel set up! Staggered injectors with high
octan
fuel coming in as second set.Slow running on low octan fuel.
