There are 3 differential valves: One for ionized air, one for EGR, and the other is for filtered air from the filter housing.
A fitting below the throttle body provides engine vacuum, this is what pulls the different gasses into the engine through the differential solenoids (needle type valves).
It think the butterfly valve was also modified since water disassociation releases enough oxygen to provide a stoichiometric ratio. Stan states in the TB that the 2:1 stoichiometric ratio is maintained throughout the engines operating range.
Im referring to the 125 psi pump required to send the air, exhaust and water to the injector... the final embodiment of his design
apparently he mixed ionized air and exhaust gases with water mist in some sort of mixing chamber , then sent the entire mixture at 125 PSI to the injector to finalize the charging and firing of the mix.
at first he had a canadian patent where the three elments were sent to the injector via 3 different hoses and mixed in the injector...later he developed a better version where the mixing manifold was used before the fuel was sent to each injector
i can see how a 125 psi pump was required to get good flow based on injector solenoid pulse width.... there were 4 solenoids, one for each cylinder, and they obviously were controlled by the 4 LED s in the distributor... but how do you get the ambient (gas processor) ionized air into the mixing chamber

any ideas on the kind of pump used? or the configuration?
