Doping an internal combustion engine with water vapor

[Flytox]

Mmmmhhh, I see that it cogites ..... Not well understood your mounting ... Your 2 pipes at the bottom, they go together, it looks like a GVI !? While the fire extinguisher is bubbling !?

[xaveco]

No I do not have a GVI, in the photo, the bubbler is the fire extinguisher, maybe by turning the photo in the operating direction it will be easier to understand:



explanations:

-The big tube is connected between the exhaust manifold and the muffler, all the exhaust gases pass through., (The gases arrive from below)

-The small tube (reactor) goes into the big one and comes out through the two holes in the big tube.

-The hole from above (entered from the reactor) comes out in the fire extinguisher at the top of it. This is where the steam is sucked.

-The bottom hole (outlet of the reactor) comes out of the large tube below the fire extinguisher, just above the exhaust manifold. It will be connected to the tractor intake by a copper tube.

-The fire extinguisher which is welded to it around the large tube in order to heat the water will be filled with water at almost half.

-The bent pipe welded to the extinguisher is just the water filler cap (I put it this way so that I could not fill the extinguisher completely so that the water could not flow into the reactor)

-There is a tube that goes above the fire extinguisher plunges to the bottom for bubbling. (we do not see it well on the photo.)
I will put more explicit photos as and when mounting.

So what you call "reactor" is a rodless reactor ..... ie ... like a GVI.

Just a few remarks, for a 4 liter engine, it seems to me that the diameter of the large tube (48 mm), through which all the exhaust gases pass, is a bit small, especially with your reactor inside (22mm). It seems to me that you are going to throttle your exhaust too much (risk of engine heating and poor performance).

Chai not if you planned, but it would be necessary that you fit a "deflector" near the suction of the vapor inside the extinguisher. With the chaos of the roads, the water ripples in the bubbler and you risk swallowing a big sip of water at once (dangerous for the engine).

If I have a rod in the reactor tube, when I took the photo it was already in the tube. For the risk of strangulation, no risk, it's almost the same diameter as the original tube and the tractor is old so the engine runs slowly (which is excellent for doing pollution tests)

Good idea for the deflector, the risk is minimal but real so if I can reduce it

For those who have not understood too much here is a small simple diagram:

Hello xaveco,

Clever idea extinguisher .

Some fixtures have an external air supply (~ 30 °) entered
reactor, I say this to memo.

[Flytox]

If you have not already planned, you can easily add a transparent hose to be able to monitor the level of fleet in the fire extinguisher.

[xaveco]

Thank you for the advice of the transparent pipes, I had already thought about it, it's true that I forgot to put it on the diagram but if you look well on the photo, on the left of the extinguisher I already make holes 2 for that

[xaveco]

Uh sorry on the right rather I'm a bit out of phase right now

Hello everybody

I can't help publishing my rag tests so much
vapor with a depolluting effect (at sight) on exhaust gases.

Attached is a test assembly of a water doping without reactor on Renault 4.
The bottle was half filled with hot tap water, then kept at temperature by the contact of the exhaust pipe.
Steam is pushed towards the intake (upstream of the carburetor) thanks to the electric inflator, so there is no restriction on the intake.
(without the inflator the vapor is too little sucked, it would have been necessary a larger diameter pipe with restriction)





My 1st cloth test attached to the end of the exhaust was carried out on a 4 km journey without steam, left cloth, then the same journey with right cloth vapor.





Very very satisfactory result !!!



but failed tests the following days
