Running an internal combustion engine?

[Super God]

For now I'm gonna buy those tubes turn off the fuel pump and turn it over.  If it runs, yay, if it doesn't I'll just add one in parallel or series.  Whatever works.  Apparently you just run the gas into the intake manifold or whatever and the engine vacuum does the rest.

ZFF, Archie Blue in New Zealand came up with the idea of bubbling exhaust gas (EG) up thru the bottm of the cell.  I think he used perf plates, though.  I recall a series of three cells, with differing volumes of EG added.   Might be worth the search."archie blue gas"

IronHead speaks of using EG to temper the octane of HHO.   My approach (ain't done it yet) would be to mix EG in the flashback chamber, then feed it to engine intake. 

Adjust ratio till no apparent timing issues arise, then slowly pinch off gasoline flow whilst adding ever-increasing HHO/EG flow to carry load.

It matter not wherever y'all get yer HHO from at this stage; what is important is grasping the dynamics of fuel substitution.

Or at least that's my view from the pond...

@Turtle - The only thing I believe I need to do with EGR is to ensure the spent exhaust gas is cooled through a heat exchanger before feeding it to the electrolyzer.

@All - Somewhere in the HV HHO thread IH put up a schematic of the plumbing for HHO into the intake manifold and air duct in front of the butterfly at the plenum. Pretty much the same as shown at Magdrive. I put a hose through the intake pipe, positioned the hose opening facing the butterfly, brought it through the firewall and put a vacuum gauge on it. I figured at wide open throttle and higher RPM there might be enough velocity to see measurable vacuum signal. Nope. If I put my finger over the tube I can barely feel any suction. What this means is, unless you can create a venturi in the intake air stream to create a strong vacuum signal proportional to velocity, just send your HHO to the intake manifold vacuum and be done with it.

If anyone has an idea how to build a simple venturi to create the vacuum I just described, please share.

There is something wrong. Do you have an air filter in the car? Did you put the HHO line between the air filter and the throttle body ? Is you air filter well sealed ? Does you airfilter have any holes in it that might cause 0 vaccum  ? You should have very high vacuum at high acceleration. Diagnostics is very important here . Don't just give up  on something we have already proven without looking for the problem.

Also are the any other vacuum lines in that area , between filter and throttle . if so check out
any check valves that may be failing.

No dont just send your Cell vacuum line to the manifold and be done with it.
When your engine is at high acceleration your manifold vacuum will drop way down.
So you will be producing more HHO at idle then you will in acceleration . Then you drop out of acceleration .Guess what happens if you do this. You back feed HHO through the entire vacuum system and can migrate to the  break booster. This can fail your brakes completely . This is only true if you engine is running correctly . If you have vacuum problems to start with I suggest you solve those problems first !

I had to modify the tube end so that there was an angle facing the throttle body (facing away from the air filter)  like:   /l  .   It worked well so that now there is no foam on top of the solution, it all gets sucked up.  Kinda like a rock in a river creating an eddy.
