Computer Control of a PWM design. work in progress.

[Lanmasterd]

  Hey Lads and Lasses

New to the site not to the work ive finally desided i cant go it alone we gotta band together to band together to beat this HHo production problem.

so starting now i will be publishing my work on here hoping i spike an interest in it.. so far i have only been refining designs currently on the market and using wat i find to come up with my own ideas and generate a new approach to this issue,,

first thing is computer control of the pulse and gate train.. then moving on from there.. see Attached a finished PCB design for a modifiable gate and pusle train based on stans d14 design with a few modern tweaks for building and proformance .. and use in a car or my case a motor cycle....

hope to see some feed back..

as this will keep on comming as i start computerizing my design..  and much much more ..

Its all about stressing the bonds in the water ...

What are you using for source clock?

Thanks

[Lanmasterd]

on the model show above the clocking is done by the circuit its self.. on the design in the works im using a atmel Atmega88 32 pin config with internal 8mhz clock .. might have to use a crystal to get desired range i need....  that and some digital pots for control of the circuit..

its still very in the design stage,,,

i have a lot of experiance with digital design and frequency modulation using atmel pic's .. they have millions of uses..

Howdy Lanmasterd,

That circuit looks like this...

Do you have a schematic for the computer controlled circuit?

Well, with a microprocessor based design you could lock in the pulse train.  With the potentiometers your pulse train will be shifting around every time the humidity changes.  I have been knocking around ideas here in overunity.com for a while.  I have seen a few designs but it seems that no one is willing to put in the engineering effort to actually design anything.  Here is a brief synopsis of what I feel a HHO controller needs to be a reliable controller of HHO production in a commuter vehicle.

1.  Solid state, automotive quality electronics.
2.  Microprocessor or microcontroller controlled pulse train.
3.  High voltage stainless steel Electrolyzer.
4.  Mass air sensor.
5.  Exhaust oxygen sensor.
6.  Engine RPM sensor.
7.  Throttle position sensor.
8.  Vehicle speed sensors.

Modern gasoline engine management computers do an excellent job of measuring airflow into an engine and metering the fuel to exactly the perfect ratio.  This is what makes modern engines so crisp and responsive.  When you romp on the gas pedal the car moves, no questions asked.  The modern consumer will expect no less from a an HHO powered vehicle.  This is a fairly difficult situation to deal with.  Not only is a modern engine management system controlling the fuel metering it is also controlling the spark timing.  In order to replace the gasoline engine management system you have to replace the gasoline with HHO but also monitor the array of sensors around the engine and produce the spark timing to run the engine.  This task in and of itself is pretty large.  Most experimenters that I have encountered want to produce HHO and pipe it into the engine and nothing else.

If you want to make HHO fueled internal combustion engines a reality there has to be one of two scenarios happen.  The first scenario is to redesign the engine management system to handle HHO instead of gasoline.  Use the same sensors around the periphery of the motor and replace the central computer to run an electrolyzer instead of the fuel injectors.  The spark timing can remain the same, but first you have to understand the spark timing before you can program it into a new engine management control computer.  Designing the computer controlled ignition spark timing is something the auto manufacturers have spent years developing.  The second scenario is use the original engine management computer which can read all the sensors around the engine, control the spark timing and  we really don't need to know much about the inner workings of the engine management computer itself.  But the tricky part about this is interfacing the fuel injector pulses to the HHO generation system.  As the engine increases in speed the fuel injectors fire more frequently.  We can use these pulses to drive the HHO Electrolyzer.  Whether this is possible directly or indirectly is yet to be seen.  It may be possible to wire the fuel injector wire directly to the coil that produces the high voltage pulses that drive the HHO electrolyzer.  But then again there may be a possibility of signal crossover, in this case we can design an interface circuit that uses the fuel injector pulses as inputs, then develops a slightly modified pulse train that runs the HHO Electrolyzer.  This is where a small processor would come in handy to monitor the fuel injector pulses and generate an arbitrary pulse train based on those pulses to drive the HHO Electrolyzer.

I'm including a schematic of a possible digitally controlled HHO driver circuit.

OK, Have fun with that...

thanks for the replay z.Monkey

the info you provided was handy.. yes the pbc above is the D14 design as i stated in my post..

im using it as a test bed and conditioner for my coils currently,,i have 3 of then each set for different pulse trains.. first is slow and long second it matched pulse to gate and 3rd is high pulse high gate,, i leave my coild attacted to each of these for 3 days to have them conditioned.. and dry then in oven ..

yes i do agree that all parts must be solid state and no moving parts.

My schematic will be available in a week of so with work latly ive been home late so the weekend ill have time off to do it rite..

IM not gonna be doing digital fuel injection first im gonna work from a simple carb and spark and timing .. then once that is working ill move to a computer based fuel injection system.. 

keep it simple.. Occam's razor
The principle states that the explanation of any phenomenon should make as few assumptions as possible, eliminating those that make no difference in the observable predictions of the explanatory hypothesis or theory.

yes and it does happen to often we have people how say but not do but i butld all the time im now finally publishing my work..

Free energy Free Ideas is my moto..

ill update with my details for my design later in the week
