Doping an internal combustion engine with water vapor

[Flytox]

Test with venturi assembly on the inlet to suck the vapor from the reactor. Historically I had already carried out this assembly and had abandoned it because of very large condensation of float in the intake manifold. This collector forms a big low point which lends itself too well to the accumulation of fleet ..... Dangerous! . .

Since I have an exchanger to heat the intake air (about 66 ° when cruising) the condensation problem should disappear.



Note: The installation of an exchanger to stabilize the temperature of the exhaust gases entering the GVI has not been carried out (still under study: mrgreen :).

Hello

instant consumption of 3.56 liters / hour at 122 km / h (very good!)

I won't qualify it as very good, ... but rather excellent, reduced to the distance of 100 KM, it would or should make 2.91 l / 100 ...

or it is the consumption of your scooter (with 4 wheels)

the temperature drops to 70 °, but if the economy is still there, why change?

Hello

There is a strange point in my readings, an instantaneous consumption of 3.56 liters / hour at 122 km / h (very good!), But at the same time the vapor temperature is breaking down at 70 °.

Can someone confirm if we can drink well at this steam outlet temperature?

Not bizard but normal until you drown the reactor or exceed the capacity of the mainsail

As I do not have an instantaneous consumption reading I cannot confirm this, but if I am based on the exhaust temperature which is indirectly related to the consumption it does the same thing, although I never descend to 70c at the reactor outlet.
What I noticed this condition happens when your reactor is hot and it receives a slight excess of water, the reactor outlet temperature decreases that of the exhaust drops (the efficiency is better) but it is short. duration, if I continue to operate with this water consumption then it becomes unfavorable.

The performance is less good without a venturie (do not put a venturia with a neck that is too small slightly higher than the inlet of the turbo.

3.56 liters / hour, that's what the instantaneous flowmeter says, this corresponds to a stabilized speed, on the flat, without wind, unloaded car etc ... Over 850 to 950 km from a full tank of fuel, with the many cold starts, a little town, etc ... each time it is in the 4.7 liters / 100 from 18 ° to 37 °.

the temperature drops to 70 °, but if the economy is still there, why change?

At this temperature we condense, accumulate the fleet somewhere in the circuit ... until the engine takes a sip. There where everything can break, the water is not very compressible ... From time to time, he warns by making a few "hiccups" of his discontent ....

My venturi is not working as expected (just -10millibar at 95 km / h).





I suppose that the reason for the non-functioning comes from the fact that the section of the 12mm diameter copper tube is much too big compared to the 36mm diameter of the venturi neck. By cutting the pipe flush on the conical part, it should improve !? Or flatten the tube 12 so that its front surface decreases significantly in the axial direction. Any idea, anyone ???

good evening Flytox

I wonder if at the orifice of the small tube, there must be big turbulence due to the size of the pipe and its configuration.

why not insert a copper elbow too and have the opening at the current location, but perpendicular to the pipe. elbow to be placed in the part where there is not yet the tightening of the venturi.

currently the constriction is 14mm and the orifice is 12mm. I would therefore say an elbow and a piece of pipe of at least 26 mm if the vertical part of the incoming pipe is placed just before the venturi.

it should eliminate turbulence and have a more regular suction.

I think it shouldn't be necessary to work the incoming pipe despite its 12mm diameter, as it would be in the larger part of the pipe. unless it's possible to make it oblique to the rest of the pipe, but I don't know if that would improve anything. the best remaining an elbow and a straight part penetrating the venturi as I described above.

I don't really know what you mean, won't you make us a little crobar ???

I was thinking about it, but I'm not a crobar artist, I'm working on it dart-dard



Voila, I am really not an artist, I used paint which is not great for drawing but it illustrates what I wanted to say. the proportions were not respected, I am sorry. but if the vertical part is furthest from the venturi part, it will have much less adverse effect on its operation

Hello

simply retract the tube behind the venturia neck, even in the middle of the neck it works, not necessary that it penetrates into it.
Certain venturie for aircraft giroscopes, it is a simple narrow slit at the neck of the venturie that syphone in the slit.

Finally, that's what I understood He is your crobar! I put this good idea aside. It has one drawback, the pipes form a real viper knot at this point, I do not really see how to connect without significantly lengthening the steam supply hose.
