Thanks Helz_McFugly, ridelong & Philldpapill for your reply and information.
I am able to build circuits from a schematic only, so I'll check my supply box, and see if I have all the stuff to build that recommended circuit, and if so, give it a whirl, and see what happens. I'm pretty sure I already have all those parts required.
Other than this circuit, what PWM circuit would you recommend as a "basic" system to start off with?
I don't want to mess around trying to calculate electrolyes, I would rather just build a circuit as long as it's not too overly complicated to see how it works out.
Does someone have a suitible circuit for an EFIE that would work with my 1999 ford windstar minivan? I'm assuming a circuit like this simply goes between the O2 sensor on the manifold, (cut the return line and place the unit in between the computer and sensor) and the van's computer?
What about the actual electrodes? Should I use plates, or steel tubes? What are the recommended guidelines for how much current draw and hydrogen production I should go by? Is there a COMPLETE system encompassing everything that "most" people are using right now? (Schematics and electrode designs)
My engine light has been on for about a year now as it is, lol, I went as far as to have the computer hooked up to the van to read the code, and it showed the O2 sensor as bad, so maybe it needs replacing as it is, or maybe the EFIE circuit will actually repair the issue, reporting the correct voltage back to the computer as maybe the sensor is just getting old and sloppy, and not returning favorable data to the computer anymore, I heard that's a common issue with those sensors.
If I can obtain a bit of guidance, and a "proven working" set of schematics for both the EFIE and the PWM circuit, then I could build a working prototype, and improve on it from there onwards, but there's no sense in reinventing the wheel, and spending a year researching everything that others have already done if it can be helped, so I would REALLY appreciate it if someone could bring me up to speed, so I'm current with the current "working technology" at hand. Perhaps after I reach that point, and can do some serious research and experimentation, I'll be able to return some contributions to the group one day in the near future.
Also, one of my other questions was about the electrolyte.
Again, I was led to believe that a simple shot of baking soda in some water was good enough, until I started reading, and found out about all the complex electolytes people are using.
Will good old baking soda work just fine with a PWM system? Or do I have to use Lye or something else? Additionally, must the electrolyte be replenished, or dumped and refilled with fresh electrolye peroidically? If so, when and how?
Thanks again for your info and guidance, it is mush appreciated!
