Running an internal combustion engine?
« on: July 22, 2007, 11:01:06 PM »
Ok, I have a 1995 Oldsmobile Cutlass I picked up for 150$.  It's my first car and it runs fine and stuff.  I wanted to know if it would be possible to hook up a hydrogen on demand cell and run it straight off hydrogen and oxygen (NO AIR) from the cell.  Assuming the cell outputs enough hydrogen and oxygen, would it be possible to just hook it up and hope for the best?  I don't care about power or anything, it's not a powerful car anyway.  It's a 3.1 liter V6 if that helps.  I hope that 49 1 inch stainless steel tubes will be enough! :D

Anyone with auto experience have advice?

Sweet, once I get a job and earn some money, I'm ordering me some stainless steel tubes and running my car on hydrogen and oxygen. Woohoo!

I'm glad to see the creation of this thread. If it didn't exist I was going to create it.

The one concern I had is with regard to adequate HHO to run the engine. After a lengthy discussion with a highly competent auto mechanic, he explained to me that temps within the combustion chamber are controlled on a normal ICE using EGR. My thought is to reroute some or all of the recirculated exhaust gas through the electrolyzer(s) from the bottom up through the plates to A) provide the volume, B) regulate combustion chamber temps, maybe mitigating the need for special engine mods, and C) agitate the cells along with engine vacuum to produce HHO more efficiently.

Not too sure about throttle response though. It may still be best suited for steady state running conditions such as is needed for electric generation. No problem. Just keep batteries charged enough to run electric cars. My dream car? See the Tesla Roadster.

I'll keep everyone posted on my progress. And please join me in sharing your thoughts with lincolninked on his thread at http://www.overunity.com/index.php/topic,2837.0.html

Cheers,
ZFF

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.

@IH - In the short time that you've known me, have I ever given you the impression that I'm a quitter? I am, however, in need of some ideas and not afraid to put it to the group.

If anything, I routed the tube too perfectly in front of the butterfly, in line with the air flow. I think maybe inserting it more at right angles to the air flow and facing an angled opening downstream as per Yikes may be better. Better still might be to leave my tube the way it is and flare the end or put a tiny funnel in the end, wide end toward the butterfly. The sudden increase in velocity around the lip of the funnel should create a dynamite vacuum signal.

Sorry man I did not mean it to come out like that . I meant more about quiting on the hook up because the outcome was not working  with out  seeing why you had no vacuum where all gasoline cars that run correctly  should have high vac under these conditions .

Again I was not calling you a quitter  . The fact is what you have done for this forum is rather fantastic and I have to thank you for that . The step by step build you are doing has my highest praise .

The  tube must point to the butterfly as shown in the design as well.

Also  the flare idea works very well to increase vacuum along with a slight angular cut .

I don't know if you saw my latest youtube video last night but it appears the S-cell generated about 1 LPM @10A. There was still quite a bit of leakage around my original gasket. I'm sealing up the removable lid tonight by gluing a frame to the top lip of the tank with a more pliable gasket, much like the drawing you presented except that the frame hangs over the interior of the tank, not over the exterior edge. Still leaves me room to remove the plate cavity, etc etc etc.

I cannibalized a check valve last night because, with it cut off the way I did, it resembled a mini funnel with an large dimension about the size of a nickel. Stuck that in the tube inside the air duct with the wide end facing the butterfly. It managed to pull about 1" Hg. I would be VERY interested to see reports from others of their measurements taken from just this location, no other plumbing, and exactly how they did it if they can get more than I just did.

To experiment I will be enlarging the size of the funnel to raise velocity even more at the mouth of the funnel (ie drop pressure). I will also be testing various forms of tubes inserted at right angles to the air duct as I have seen elsewhere with the wedge cut facing downstream and see how well THAT works too.

I realize the S-cell is a teaching aid. 1/4" spacing really is too far for lower voltage applications. But is does make it easy to get a good look at what's going on and provides a common platform to compare notes with. Soon I'll be ready for a PWM supply. I'm sure you can point me in the right direction to get me off to a good start.

And just wait until you see the design I'm cooking up for a finished electrolyzer. 3 times the plate surface area, 3 times the circulation velocity (maybe more), 1/6 the leakage current per square inch of plate surface area. Closed circuit cooling. I can't wait to see the numbers when I flip the switch.

Two questions here: Where's a good place to find SS wool? and what size works best?

SS  wool , grocery store . Just pack the bubbler with it, loose but evenly .
Keep up the good work and looking forward to the next builds.

AKA pot scrubbers.  Also a trip to a machine shop scrap hopper when they're cuttin' stainless.
