Citroen AX diesel 1.4

To replace an air filter on my mob I used my mother's old tights with holes But as a rule I did not put anything. To use a cloth just blow through to realize its resistance. Not all fabrics are as resistant to air.
On my cars I used mobs air filters and lately even better, air filters for breather tunning way. It's like a filter for mob but smaller.

Hello,
according to your schematic diagram, to limit upwelling try to flare your 12-14 tube until it touches the 15-21 tube so there may be only steam that could pass.
And your air intake will necessarily be bigger.
Otherwise, I look with interest your manips because I too have a motor that does not consume much (106 1,5D with 4,3l / 100 on average without pantone) and if we could save -30% it would be nice.
So I can only say "COURAGE" to you.

Hello,

according to your schematic diagram, to limit upwelling try to flare your 12-14 tube until it touches the 15-21 tube so there may be only steam that could pass.

It reminds me of a test with my hollow stem: I placed 3 concentric tubes between the GV and the stem, with a very limited space (1 / 10è mm?) In the hope of letting only steam pass. It did not stop the water level from rising ...

On the contrary, I believe that by reducing the space for the water too much, capillary rise is encouraged.

On the other hand if one leaves a large surface of exchange with the water, it represents a larger volume to be heated. I'm amazed that Camel1's GVI (TM) does not have (or has) a lot of upwellings, while it also uses an annulus of 1 mm only ...

Hi Crispus!

I am your adventures, and see that you do not chime to make manipulations!

On the other hand if one leaves a large surface of exchange with the water, it represents a larger volume to be heated.

There, there is a little subtlety, because the exchange surface and the volume of water to heat its two independent things. The exchange surface is fixed by the dimensions, the volume of water by the level line, at the bottom of the GV.

I'm amazed that Camel1's GVI (TM) does not have (or has) a lot of upwellings, while it also uses an annulus of 1 mm only ...

I like the (TM) but hey, we share everything under Copyleft ...

For upwellings, two things:

1 °) your reactor / compact gv does not offer the same geometry as our separate in-line reactor / gv assemblies. Consequently, fluid flows, pressure losses, local pressures and depressions are necessarily different, leading to behaviors that can diverge ...

2 °) The upwellings are due to the suction conditions on the outlet of the GV.
In my experiments on forcing the suction towards the reactor, I pushed the restriction far, to the point of "turning off" the mainsail.
Basically, the more it sucks, the higher the water column goes into the GV (like a U-shaped depressometer).

As long as we are in a low depression, it's fine, but as soon as we want to push on this side, we unbalance the level tank / GV.

And with the last mod with the balancing tube, we cancel the problem. But for this to work, it is necessary to pique towards the exit of the GV, which is hardly feasible in your case ...

Your integrated system raises the problem of the independence of the air and steam settings, making the dosage difficult, and therefore the optimization ... so that you risk, during your tests, having a GV that provides, and an inactive reactor, where the opposite ...

You may have to consider returning to a more classic configuration, finally, it's you who sees ...

Good luck !

Hi Camel1,

Thank you for your follow-up and your comments, always welcome.
On the other hand I see that I explained myself badly by saying:

On the other hand if one leaves a large surface of exchange with the water, it represents a larger volume to be heated.

I was talking about the water / air exchange at the base of the reactor, not the heat exchange exhaust / water.

In fact, to avoid capillarity, it is necessary to avoid "trapping" the water between 2 close reinforcements. By removing these reinforcements the water level will be flush with a higher HORIZONTAL surface.

And on a depth of 3 cm it automatically translates into an increase in volume, hence a lack of responsiveness. And of course, the more the water rises under the effect of the depression, and the less it reacts!

I could see at my expense that it takes calories to boil ... Your (your) GV where all the walls is warmed up is a great idea. Thanks again for distributing it gratis

This is also why the GV works well with a minimum water level, if there is too much water it does not work anymore and it spits like a geyser.

This is also why the GV works well with a minimum water level, if there is too much water it does not work anymore and it spits like a geyser.

it is still difficult to regulate:

there is the flow to be regulated and also the final T ° obtained by the mixture "steam outlet main steam / fresh air"

if there is enough heat (large "ech / HS" exchange surface) not to "spit" boiling water at the HS outlet, the flow rate can be adjusted by the height of the water level

but for a flow of water to be respected, if the GV captures too much heat to the ech, the output GV will produce steam hyper-dry that is probably not too desirable for doping even mixed with fresh air just before entering the reactor (fresh air supposed, mixed with dry steam, produce wet steam)

the ideal would be a GV largely sized to avoid any spitting of boiling water whose output would be regulated at about 100 ° C to be sure that mixing with fresh air always produces the right steam (slightly damp)

the output of the Camel1 GV comes out of the exhaust pipe, takes the fresh air inlet, to go farther into the ech where the reactor is located

it is possible that going out in this way helps with the regulation of the T °, ​​even if the template of the GV has its starting importance (not to make the steam too overheated)

if a GV reactor is simpler or less cumbersome to do: how to master and adjust the T °

it is therefore important to install T ° probes to know if this T ° is not too high or too low

in my opinion, it is easier not to create a pressure drop in the fresh air intake duct, which, arriving in tee with the steam outlet of the GV must not create suction in it at the risk of disturbing the constant level of water
it is not the pressure drop of the fresh air pipe that must regulate the flow of water

Hello

This is also why the GV works well with a minimum water level, if there is too much water it does not work anymore and it spits like a geyser.

the ideal would be a generously sized GV to prevent any spitting of boiling water whose output would be regulated to about 100 ° C to be sure that its mixing with fresh air always produces the right vapor (slightly wet

A GV must have a fairly well-proportioned heating area
Although my system is not exactly a SGS but it works in a similar principle.
It's all at once, a carburettor, a bubbler or a GV
If I drown it, it is a bubbler, if it leaves a little water in it, it is a GV and if I make it run dry it is a carburettor that spits in a preheating chamber.
It is this last solution which will have been the most effective
Dry GV, carburetor (self-regulating) that brings water according to engine demand.
What must be made automatic is what the downstream reactor according to the power of the engine, so the supply of air and water in the GV must follow this proportion.
I have long operated GV with a bottom of water, I realized by making the city so very little water at the beginning on highway there was an améloiration on the driving, I modiifé the sytéme so that l supply of water only as needed.
On a normal turbo diesel 100 110kmh the GV (or my system) is behind the reactor the exhaust heat is not high and the relatively short steam path I placed it vertical to eliminate the big drops, I did not measure the temperature at the entrance of the reactor, but I support below 100c
Although if one examines the assembly of Michel on the Mercedes the steam + air journeys in the parallel exhaust to the reactor to go to join the entrance of the reactor the entrance temperature of the reactor must be in 100c and more, according to the quantity of air that is diluted with steam.
I do not know if it measures the temperature at the outlet of GV or at the entrance of the reactor, but I think it is in the entrance of the reactor that we are interested ..
On mounting VITRY Rombas the same principle tracking steam in the exhaust in its hottest part to go to the reactor.
In my assembly I privileged the exit of the turbo the hottest part for the nose of the reactor and the rest to make steam

All the work I did was to make the reactor run at low speeds from 80kmh to 110kmh I know it works well at 140kmh, but little interest for normal use at least in America we are forced to drive at 100kmh tolerated at 110kmh
the biggest problem in a carburettor mounting you have to master the jet run with low vacuum and look for the right nozzle to have enough air, although a simple drip also does the trick. There is a way to do better on this side, in the immediate is to find the ratio steam / air which is related to the temperature and probably to the point of saturation,
This is one of the reasons that makes the thing difficult the temperature makes changing the saturation point
besides that it is a GV or a bubbler if we know the consomation of water, it is enough to feed it drip if the heating capacity is good there is no accumulatinon of water.

Hello André

in principle, the air must also pass through your "carbu" adjustable in water flow by the needle screw

in a GV the air is free to access, it is used to convey the steam produced by the strong heat

and if the ech heat is less strong (during a deceleration or less fishing on the mushroom) there is never any spitting production of water taken by "fresh air" since the water at the bottom of the mainsail can only come out by evaporation

this is what makes the great tip of the GV proposed by camel1 (steam production is regulated by available heat)

if you say that the most efficient is the dry bubbler, it is not impossible that the main advantage of this example is the brutality the evaporation of the water which gives the best result (the consequence of this brutality would produce more essential ions to the reactor, whereas with a slow evaporation, the produced ions are clearly less numerous)

knowing that once the ions produced, they must be used immediately by the reactor

Hello,
Andre said:

question:
What is your exhaust temperature at 140kmh when it works?
and when are you at 50kmh?
If you stay in first gear in the towers you have to hang the reactor?
Obviously, anyone with measurements is welcome.
suggestion on André's reactor:
If you extended more your bubbler in the exhaust (+ 10 / 20cm), can this help to run the reactor at low speeds (50kmh)?
I hope my ideas are not too naive !!
