2 stroke Water injection

[Terry Sare]

Just read a surplus catalog last night, cannot remember the name (Surplus 
Center??), that had high pressure hydraulic, air, and water valves in it. Since 
the ones for the high pressure washers were made for water, that might also be a
source to consider.

  Just a thought, but there are electrically controlled hydraulic valves
good to 3000+ psi.  Many of them are made out of stainless I believe so 
they should stand up to water.  If the pumps are of similar construction, 
you might be able to purchase one and get a small motor to run it up to the 
desired pressure (or use a pressurized tank).  If you get the pressure high 
enough, you might be able to machine an aluminum nozzle that gives a good 
'spray' due to the pressure involved (sort of like a windshield sprayer).
I THINK the K-jetronic mechanical fuel injectors have moving parts 
(probably steel) and wouldn't like water.  Anyway,  Pumps and valves run 
around ~50 each.  Go check out the hydraforce web page as they make lots of 
cool electronically controlled hydraulic stuff.  Check out what the valves 
are made of though or obviously they will rust.  If this helps helps any 
(or sparks any other creative thoughts) I'd be interested in hearing them.
  Another thought:  Is Nitrous an oxidant?  You might be able to use an NOS
fogger as the nozzle and the the NO2 solenoid if they are made of 
stainless/aluminum.  NO2 is at a relatively high pressure (700-1100psi?) so 
I doubt the fogger has moving parts (could easilly be wrong here though).
