ADblue SCR: adding urea against Nox?

Hello
for the urine, by letting it "ferment", then by passing it by electrolise, what molléculle will we choose?

Hi everybody.
Do not waste your time here because, as the webmaster told you, it is a pollution control device to reduce NOX.
A mixture of water / urea + other chemical components is injected into the exhaust.
Rather see on the site of Renault trucks.
All their trucks will be equipped with the 2006 device.
The additive (to fill the auxiliary tanks) called blue ... I do not know what is going to be sold in gas station anymore.

Hello
Finally the test is done on mountain 245km, difference in performance or conso not detectable driving.But slowed 50 to 100 tower higher and VERY strong reduction of the engine brake! : Cry:
Who would have an explanation; I have doubts but no proof :P

it is very interesting on the contrary.

A symptom of an explosion at the wrong time without loss of conso : Shock: (guess) case to follow ...

Yes very strange I will inquire in more detail ...

But what exactly are you doing?

Pure urine? Diluted? Concentrated? And what conso of urine / conso water?

Hello
Here then :!: It's funny
Why are manufacturers such as Renault adopting this principle for the depollution with the urine of sheep and not the Pantone?
Yet it's an easy thing to do (even more than the Pantone reactor).
There are mysteries that I can not explain. : roll:

Hello
I did not do anything bubbly I do not use bubbler for a long time I think it's too boring to manage and store in a vehicle. :(
I work in water doping with a carburetor of mob or model (in this case 707 gurtner 10 without bushel).
When my water tank was empty I (following the post I had seen on the site talking about urea depollution) simply pissed (urinated) in : Lol:
here it is all con.N't not made my usual trips and on 340km I can not give a measure of conso reliable nor perf (that of the mountain so no measurable peak speed and always a caffrine in front of each out of pin in second).

In the scientific genre ...
Have you eaten a lot of red meat lately?
Have you abused beer?
It's important for the quality of the additive ...
Go, good Christmas everyone!
And think of urinating tonight in different containers to store, to test later, the effects of different compositions from hearty meals ... : Lol:

Hi everyone and congratulations for the humor .......

otherwise, the product used by renault trucks, is called AdBlue:
32,5% urea + demineralised water.

the principle is a principle already used in industry (thermal power plants, incineration of waste, etc ...).

it is to clean up using ammonia gas (with a C and not QUE).

in fact, as the manufacturers did not see too much opportunity to ship a cylinder under pressure of ammonia.

a trick has been found, use urea (by-product of ammonia), which in the presence of some heat, (the exhaust), turns into ammonia gas.

and then the ammonia transforms the nox into nitrogen and water vapor.

at the level of the consumption gain it comes solely from the adjustment of the engine, at the level of the injection system.

the engine is better tuned, but it produces more nox, which is then transformed into the exhaust.
