That's what I'm referring to is the tach pulse...and use this to control duty cycle so that at idle, we're not making max production, while sacrificing 'some' at highway speeds... we could also use the speed signal from the transmission to the ECU if you want something more relative to speed.
Again, I have access to this info as well specifically wire color, location, and pulses per mile. This could be used to control duty cycle to ramp up production as speed increases and 'top out' at the sweet spot for your motor at a given speed.
For example some newer GM vehicles have a green/white wire behind the radio that gives you 4000 pulses per mile. The radio needs this pulse info for their speed control volume feature. If needed, I can also tell you where at the ECU this wire can be found as well, and for other cars.
No need for magnets on the driveshaft. Although, I've used that method for getting a speed signal on some older vehicles while installing cruise control.
I have some GREAT access to good information if anyone wants to try to incorporate it and see if it works. I'm just not an electrical engineer and wouldn't be able to incorporate this idea into a working circuit.
YEP.. YOU ARE ON THE SAME TRACK I"VE BEEN ON.. SEEMS LIKE THE WAY TO GO. on http://www.freewebs.com/mobilehydricty
, I wrote( a new approach to EFIE /MAPS ),and a block diagram indicating mixture burns and a servo to control hydrogen flow based upon accelleration and compartive feedback from the ecu. The point that seems to be bypassed is , that we are not dealing with a hydrogen /oxygen built engine.. still an air pump, so the mixture of owy/ h2 and petro becomes important in the gosh almighty gasoline engine... The particulars seem to always indicate that , people are trying to make a gasoline powered air pump run on as much BROWNS GAS or applicable flashpoint materials as possible , hoping to get better gas millage. In fact , the electrolizers, are designed for and should be used as a suppliment to the mix. Therefore the amount of BROWNS GAS should be controlled , The method that seems to work the best for me .. is to use electrodes , limiting the voltage and current to 3.2 vdc at 1.85 amps at the max , on the simple tanks , I,ve been building, Therefore at idle or 1100 rpms or so, the amount of H2 needed is less and therefore should be regulated by the power supply / limiter circuit and I think now with a servo controlled valve that is responsivie to the emisions in the exhaust, with inert gas feed back . AS you accelerate the burn conditions change , temp , etc ..all variables that can be compensated for by feedback. The idea is to achieve the best burn /ie combustion with the fuels at hand at varying loads .. Been working on a design pcb to control these aspects.. your info would be greatly appreciated.. I try to look at things from a dumb standpoint, then engineer or design some type of circuit to retrofit the needs. Sometimes called, my ignorance is sometimes my brilliance in asking why or how does this work etc. I haven;t used the magnet concept in some time either, except on a few old tractors, I,converted ,and needed something to use as a feed back monitor in relationship to rpms, works pretty good on a beast of such that is basically all brawn. On my website, there is a practical circuit , I designed, for cooking with hydrogen.. haven't got to build this one yet, but in theory it should work... this circuit has some adaptable x factors, that may help.. Hope to keep in touch with you more in the future, GOOD WORK OLD CHUM. and I could use some info that would help me in designing a pcb that could be used in a general mode for all purposes. A RAMPMING PULSE , I BELIEVE IS A MUST HAVE... The school is still out for me on EFIES and such... if you can control the mix at combustion for an optimum then the amount of free O molecules is minimized, hence forth let the ecu do its thing and regulate the appropiate quanities at the input with minute changes.THANKS FOR THE REPLY MIKE
