In total agreement!
In my point of view the GMS is simply a mean stan created to generate the gas, meter, mix and inject the gas along with exhaust and ambient air to the engine.
for that if i'm not far from understanding, Stan used a frequency that is used to resonate the cell and gated it at a frequency governed by the rpm of the engine, such to create the trigger signal for the injectors, adjust the phase relationship of the shaft position and the accelerator circuit to change the pulse width of this signal to create a situation of high rate of production of gas of changing speed and a minimum (idling) .
another way i see it doing, is the frequency of the rotation directly increase the duty cycle of the gating signal if the gate frequency cannot be as high as the frequency derived from rpm... anyway 1000rpm should make 8.333hz if we are not multiplying it...
I guess the basic gate ckt (subharmonic of the resonant freq) acts only up to the engine start rotating... Maybe?
So in basic basic we could have the signal coming from the distributor and change the phase mechanically to simplify..
with few monostable timers we can set the timing for the injectors.. .
Of course there is also the safety needs like pressure sensing to stop the thing in case it reachs it .. and some others,..
i think stan dist cards are maybe used to let two cylinders working on gasoline and switch to water in an instant.. .would help if the car could stay on with a couple of cylinders and left the others for exclusive experimenting..
but as stan said kiss or you won't make it true
