concluding in the sense that it starts ^^ after mixing gasoline with water, I know not on xd but it would be to deepen ^^

a doubt for me, the bubbler, it is used to replace the fact of piercing the exhaust? is it an alternative or a plus?

because it would be easier to install on the car that I use every day ^^ otherwise I would buy a line of rab, but I can't wait to start something: p

I don't understand what you mean .... : Cry:

If you want to quickly build something, you can copy an existing montage if your car is suitable for it or make it your own. The best would still be to start with a schematic diagram, we can comment on the pitfalls to avoid. : Mrgreen:

I may have misunderstood the principle of the bubbler xd but is it not the reactor which passes in its middle?
that's why I ask if with the bubbler it is necessary to pierce the exhaust ^^ I have to revise everything I had found because even I have trouble expressing myself xd c 'is like everything, in theory I have a hard time, then I will do a hard editing that will enlighten me ^^ more "practical" than "theoretical" me lol

In the Gillier Pantone version, the bubbler is a closed container containing water (total volume of 0.5 to 5 liters?) To be located near the exhaust and the reactor. (In the Pantone version, the bubbler can contain water plus any fuel or pure fuel.)

This water is heated in different possible ways to make "steam" by:

- direct passage of exhaust gas into the water. (Bubbling)
- Passage of the exhaust pipe (or a bypass of the exhaust pipe) which passes right through the bubbler.
- Passage of a bypass of the engine coolant circuit by a heat exchanger coil in the bottom of the bubbler.

These different heating solutions can be unique or can be combined with each other. : Mrgreen:

In the bubbler, the space above the water is used to mix as desired:
- cold or hot air.
- exhaust gases.
- water vapor.
- Of indispensable tiny water droplets suspended in the ambient gas mixture.

The "preparation" of the "steam" is very important and is largely done there. Anyway, what comes out goes to the reactor.

Depending on the temperature, the pressure, the flow of different fluids, the design of the bubbler, what comes out can vary a lot and make the difference between a system that works or does not work.
Disadvantage, this assembly has a lot of inertia and produces steam "independently" of the engine demand. :frown:

The Instant Steam Generator (assembly of concentric pipes functioning as an exchanger) slips into the exhaust a little after the reactor and performs roughly the same functions of steam production as the bubbler except that the steam flow reacts "more or less" in proportion to the throttle control.

ok, i still have some for theoretical moment ^^

there is a section on the forum where are the different assemblies exposed?
to compile, this seems to me the most practical xd.
I'm going to invest another exhaust elbow to do all of this, thank you, on the Audi it starts from the turbo and stops under the apron ^^

business to follow;)
thank you for the helping hand: p I would probably still need it ^^

There is also the search engine ...

Good reading.

Hello,
I am working on a bubbler, and I have several questions on it, I can not find on the net.

is it essential that it be housed against the exhaust?

Then, I saw the pipe which is immersed in water, but I cannot find any precise rib, does it affect the section of the tube? ribs have been found more effective than others?
I do not really find a diagram explaining the entry of free air, if I understood correctly, we can do it on top and through a system that heats the air, right?

and finally, are there sizes or any size that works? because if I understood correctly, it has to be hot, so the smaller it is the better it is, right?

thank you ^^

well, i started a bubbler, i'm going to mount it on the exhaust side, the space is limited but i was able to do something that accommodates, i hope not to go wrong ...

I would post tofs of the site in question, and the proto bubbler.
I made the body in tube of 150 * 50 * 3 mm of 200mm in height,
I welded 2 round tubes of 21mm to 15 and 130mm from the bottom for liquid cooling.
for the housing of the bubbler tube, I cut a piece of tube 60 * 30 * 3mm 160mm high, I will weld it inside.
evolution soon.

The problem is when the size of the bubbler dictates that you go and house it "permanently" from the exhaust. The pipes get longer, this can create problems with condensation, low points which fill with water and can send you all at once etc ... The best is "against" the exhaust like 10/15 cm of pipes. : Mrgreen:

The ideal would be to make a removable pipe, the choice of the number of holes, their diameter and their depth plunging into the bubbler must be greater than the diameter of the pipe itself. If it's removable, you can vary it all easily. If the pipe travels through the float before opening into the bottom of the bubbler, it will allow the air to arrive at a more constant temperature. Suppression of a variable temperature for a "constant" temperature. If the temperature is right, it's all good.

and finally, are there sizes or any size that works? because if I understood correctly, it has to be hot, so the smaller it is the better it is, right?

With a ladle: : Mrgreen:
Large bubbler (> 4 liters total?) = Large inertia, long heating time, but greater operating stability.
Small bubbler (<2 liters total?) = Less inertia, shorter heating time, more unstable operation. Without using the main heating or in addition to the water of the coolant to regulate, is it not sure that the operation is very stable / usable? : Cry:
