Hello
Don't forget the small air intake hole in the top of your trap.
Otherwise the float will not float. So the reactor fills with water.
It's all stupid but it's IMPERATIVE.
GV VIDEO HERE
Try also to measure the suction that gives your admission to the reactor.
You may be sucking in drops of water too strongly.
You need an air inlet at the GV outlet to avoid this.

Thank you PITMIX, I think you have just put your finger on my problem.. Starting tomorrow morning I will drill a small hole on top of my constant level...

To michel, it is true that I forgot to specify that I had a T at the reactor inlet to mix in fresh air.
On this T I added a valve, to know how to adjust the amount of air sucked in, what do you think??
What do you think of what André wore earlier? As I have a turbo, does it not push more than the suction?? and that would prevent my intake from sucking my mixture out of the reactor?

You're welcome.
It's by doing bullshit that we move forward.
Since I made this mistake, I know how to answer you.
Very good initiative to have put an air adjustment valve.
Be careful not to roll the valve closed.
Also, don't forget to filter the air.

For your questions about suction, the best way is to check the suction of your system.
Connect a transparent tube 10mm in diameter and 2m long to the air inlet of your reactor.
Your tube must be long enough to make a U and contain water in the vertical part.
Attach this tube to a graduated board that you will place vertically on the ground.
Accelerate and control how many mm the water column moves.
Tell us what your measurement will be.
Be careful not to suck water into your engine.

Notes: on these videos my system did not have a venturi on the intake.

Another very simple way is to touch the hot engine reactor output (Zac method).
When you accelerate the temperature on the reactor outlet tube must increase violently.

hello welcome, your problem comes from the pressure of the rurbo, you need the same pressure, the steam supply, and the fresh air inlet (!!!)

is the reactor inside the exhaust pipe?

read all the montages well, and imagine, put yourself in the throttle position

Hello

You are looking for the complicated method (you know the one that doesn't work).

After the turbo when the turbo blows you pressurize your reactor in the wrong direction.

put an arrival (that's enough) BEFORE the turbo like that your reactor will always be in depression. a little venturie in addition it doesn't hurt.

Hi everybody.

I didn't dare to put the reactor outlet before the turbo because passing steam through the turbo blades, I'm afraid he doesn't like it.
This afternoon I'm getting to it and I'll tell you what tomorrow...
I'm going to drop him a direct pipe before the turbo intake, in the hose.

To denis: Yes the reactor is in the exhaust pipe

Here, after various changes made (thanks to your help everyone, THANK YOU again), I just went to try my 318, and the conclusions are:

- reduction in consumption still weak but it's Sunday, and it's going, it's slowing down, it's driving, it's slowing down... I went from 6.8L on the on-board computer to 6.5L we'll see for the rest

-on the other hand, many more times above 3000 rpm, it now pulls the little one..

- Disappearance of black smoke when I give a blow of gas.....

-And a good thing too, reduction in the smell because I also ride on HVB...

Tomorrow I will raise my float by 5mm because it still seems a little low compared to the level of my GV tube..

Thanks again to everyone

Good and well the case is in the bag. : Cheesy:
You just have to drive as usual and see how it wears out.

Hello

Do your tests with diesel, because with hvb I did not get as good results as with diesel, I have to find the right amount of water with hbv which must be different, if I rely on ZAC he consumes less water than me. Camel we arrive at the same figures with diesel..

As for entering the turbo I am 22150 km
with the panton and I didn't notice anything abnormal on the input turbine the turbine must not eat liquid water..
The real test is on the freeway or on a smooth country road.
Be careful when refueling, it makes the gasiol foam, you have to be patient to fill the cap.. (especially on trips of 200km) the filling error is more significant
At 75l the error is less.
