Doping an internal combustion engine with water vapor

[Flytox]

You could repeat the test on a slightly longer course with a little city for example to see if you confirm this result with the cloth? (4 km is really very short.)

Good evening

interesting this essay from Gildas, because in its R4 (gasoline therefore) an addition of water vapor, say hot, in the intake. its result, certainly convincing, but it is true that 4 km is not much ... and as pointed out to me Xaveco during our meeting in héraultaise land, the exhaust outlet is no longer black as is normally any exhaust outlet (petrol), it is enough to be convinced to slip a finger into the orifice exhaust outlet.

more an anti-pollution test in technical control would have been a sublime proof of success, especially that the R4 should not be catalyzed and works with solex carburetor I think.

ps: of course sliding a finger into the exhaust outlet orifice and it does not turn black is a pleasure but is not worth it anyway to slip this same finger into a well lubricated orifice. remark certainly unrelated to the subject but which makes me happy to bring!

At Flytox:
Yes, I agree, but I would have to find another method for blowing steam, not sure that the electric inflator can operate for an hour straight, moreover it is powered by its small battery.A hair dryer can it do better? Maybe you need a converter ...
I would give it a longer try if I find a better match.

Ah, hello jeff, I had not seen your message!
My R4 is not catalyzed, the brand of fuel I do not know.

A+

Hello

Gildas

for your blowing, Xaveco has mounted that of a hair dryer, very efficient, and certainly not wear-free, but it takes the distance without problem.

Hello coucou789456

..., the exhaust outlet is no longer black as is normally the case with any exhaust outlet (petrol), it is enough to be convinced to slip a finger into the exhaust outlet port .

...

Blowing by a small compressor is not a bad solution in itself. It was with a compressor that strangely resembles yours that I achieved my fuel consumption record on my R19. I fed it with a "home made" power supply.

What bothers me most about your setup is that the vapor balanced at the inlet of the intake disrupts the carburetion. Indeed the place taken by the vapor is not occupied by the air and its oxygen. This indirectly causes the enrichment of the mixture, which risks over consuming, increasing the CO, unburnt and other soot .... Your handkerchief result is not necessarily logical ...

AMHA the steam injection must be done after the carburetor. Here the air / fuel ratio will not move. There will also be a restriction to limit the suction in your steam production system, in fact the depression with the accelerator flap closed (slowed down) is very large and you risk doing something stupid (sucking a big sip of water suddenly and kill your engine).

To improve your 4L engine, you would have to put an electronic ignition on it that will help you a lot to improve consumption and the ability to absorb water without making misfires.

Another point, if your engine a few kilometers, look at the wear on the axis of the throttle of the carburetor. When it is used (very frequent) the engine consumes from 1 to 4 liters per 100Km more !!!!

In fact, I plugged in like I did jcroizer... (message4)

The ignition has been redone recently so should be well adjusted (not electronic), for the axis of the butterfly I would try to look ...
I will keep you informed as soon as I have done a more conclusive test.

Hello

You must enter with a nozzle of 2 to 3, 2mm on the outlet of the bulldozer if you enter below the butterfly.
In my case with a V6 gasoline engine, the jet is made with a small 1/8 "internal copper pipe if you put bigger the slowdown will be accelerated, if you put too small it lacks steam at 100kmh
A gasoline engine is capable of swallowing small sips of water and even excess steam. To watch as liquid water rises from the bubbler, just place a thick felt on top of the bubbler
to have a good performance on a petrol engine it takes less water consumption than on a diesel.
At the test begins by having a control on the consumption of steam at the beginning poses a small vale on the inlet inlet outlet nozzle that returns the reactor. Try on different apertures (you have to readjust your slow screw screw needle with a spring (richness) if you open your steam valve too much.
adjust the steam flow for a good yield around 100kmh, at low speeds, slow you will have too much steam and above 100kmh you will have a lack of steam.
But adjust that for the usual speeds. (having a proportional control brings a low gain for the complication, you can always try it with a manual control you will understand that doing simple at its right side.
(in winter very easy to see, just look in the rear view mirror for the exhaust steam)

The ignition has been redone recently so should be properly adjusted (not electronic), ...

Let me insist. I have several co-workers who put electronic ignition at the time on 4L, and they had reduced their fuel consumption in a tangible way. At the price of the precious liquid, it is quickly amortized .... For having tried one, it accelerated more frankly and turned rounder than mine.
