Pantone for 4L Trophy 2008

[satpavan]

Hello everybody
I am happy to read that we have already modified a 4L with the Pantone. I have one and I inquired for some time and I heard different versions "not too much for essences", "injection pb" and so I was wondering if it was working well? In the long term too, it is not "fair" to go to Morocco, but I use it all the time (I'm a little nomadic ...) in France, Germany, see further.
I inherited a last generation version (of mamy), built in 92 in Latin America ...
Can we see models already installed? and one last question, there is no problem to pass the technical control (engine modification ...) ???

Thank you in advance and see you soon,

pavan

Hello,

Well, you have pictures on the first page of this subject ...


I tried to scale my system. I will use the G + system for steam production.

Motor characteristic:
Cylinder capacity: 845 cm3
Type: essence of course

So I tried to size the GV, and here's what I got:

Having made a product cross, to calculate the exchange surface (made from the surface of the GV of the mercedes found on the site of G +): 40,49 cm2
Which gives me a length of 3,39 cm with 16 / 18 inner tube and ext 20 / 22. I find it really small.
I do not get much more with int tube 12 / 14 and ext 16 / 18 (4,3 cm)

I thought to take a length of 10 cm with int tube 12 / 14 and ext 16 / 18, what do you think?
Does this length really play a lot? the volume of water to be evaporated is very small ...

For the reactor:
Length 20 cm
Diameter steel shaft: 12 mm
Inner tube diameter reactor steel tube: 14 mm

Here is.
I had found a spreadsheet for the reactor length based on the power of the engine a while ago (when the forum PMC evolution existed) Would anyone know where to find her?

Goods.

Hello

in the length of the core, whatever its capacity does not fall below 120 / 130mm, keep an air gap from 0.75 to 1mm after the diameter and the length of the tube is less important.

What counts is a good depression and the closest to the collector for sufficient temperature.

Do not trust these calculations, as Zac says above there is a minimum in general around 200mm long you're not mistaken
These calculations are not proven
If there is length to respect I think that are more in relation to the diameter of the stem
a rod of 8mm and a rod of 30mm there is a differrence on the lengths but one has little return of experience .. (everybody keeps in the 12mm has 14mm ..)
whether it is 240mm or 190mm it will not change much on the progress of the reactor.

Okay thank you.

My intention is to connect the reactor outlet directly to the intake manifold as here:

http://reaction.directe1.free.fr/Merco220D/adm.htm (except that it will be a collector of 4L of course)

What do you think ? and I asked myself the question, namely, put a butterfly valve between the reactor outlet and this opening which would open like the throttle, to keep the engine brake. Because I read some testimonials like what pantone continuiat to take turns after a big load for example. (and my titine does not brake masses

One last question, may be stupid but I prefer to be on, if I place the reactor first on the exhaust line (the gas first warms it) and then the GV, there will be no problem to evaporate water? I mean, the gases will not be too much cooled by the reactor?

It is not the engine brake that is the concern
an entry as generous as the diesel in the rear of the throttle, it is the idle that will become a problem and the richness of the carburetion, on a big engine 3,8 l V6 this entry must be reduced to a conduit of 3,2 mm and still the slowed is accelerating, at low speeds, a strong suction in the reactor that decreases with the opening of the pappillon (the opposite of what would be desirable, but I made an adjustment for that good around 80 has 100kmh, he simply gauge the diameter of the duct entering the manifold ..

The reactor must be favored to have the highest possible temperature, at the exit of the reactor there is enough heat to boil water ..

Here is the first piece we made, the steam generator:

And the inner tube sight came out:

https://www.econologie.com/fichiers/partager/GVeclate.jpg

It is 20 cm long. Calculated length with the formula available on the G + system site (rounds to 20 cm)

The other pieces will be coming in a few weeks

That's good, here he is the GV he is beautiful!

On the other hand, how did you foresee its installation in the exhaust tube, because in the state, considering the length of the tubes input / output, I see only the solution that I had used for the 205, it that is to say, cut a hatch in the right place (it takes the slope) then set up and brazing the GV on a cover that will fit on this light, then weld the lid on the exhaust tube ...

On the merco, it was much simpler, but the configuration was perfect for it ...

Good luck, guys!

See you soon !

Thank you!

I think that we will cut one end of the exhaust tube of the length of the GV (see a little longer), cross this end of tube in two in the direction of the length, make the necessary holes, braze and then tie up with the bow.

On the exhaust of the 4L, there is a part that is completely vertical under the wing so it's impeccable!

[jeyjey44]

After a little trick to recover a line of exhaust, we could start some parts of the system:

the exhaust outlet with the holes to pass the reactor tube:


the file uses it ... the biceps!


the same but with the tube in:



(yes there is play on this side it's not me it's the lime!)

the GV with the end of the tube inside which it will be, and that we will put in place of an exhaust end:



All these pieces are waiting to be welded at a friend plumber

And the tube with its reactor rod:



Voili want, we advance!
