Already done intro to euro 6 and yep it will be a nightmare ,luckily for those with Iveco,(I can already hear people laughing) but they have managed to achieve euro 6 with SCR only
But not looking forward to euro 6, we have went from like 6 sensors to 20 sensors ,and they will all derate the engine when they fail
I remember when we took on some new 08 plate Renault Premiums,
everyone was asking WTF is AdBlue ■■?
It must have cost the firm an unexpected fortune - they use to guzzle the
■■■■ stuff. Fully automatic. But I loved those motors and we hardly had
a problem with them.
Then we moved on to Scanias. No AdBlue needed but the so called
automatics have a clutch. What a pain. Wish I had a quid for every
time I forgot to dip the clutch when I stopped.
I prefer the Scania three-over-three manuals. I never bother with the
half gears, we never have the weight.
Pats right by the way!,over this side o the pond they decieded to f us all over wae the Ad blue,no adblue and you end up on the side o the road pi…ng in the tank not great when its -30c …thank god im on old trucks.

Don’t forget to try some very cheap motorcycle parts… Haha
I have a Ph.D in a physics related subject, my thesis was the study of the IC engine & how it could be made more efficient.
I championed carburetors (in many respects I still do) & most of my research was channelled into the best way to charge the cylinder before the power cycle.
I was taught to believe & discovered for myself that 10 000 miles to the gallon of fossil fuel is economically possible for an IC powered vehicle, it is mathematically possible, engineeringly possibly yet totally impossible in the modern world.
That was 30yrs ago.
Emissions regulations were introduced to maintain the status quo. The world would be thrown into economic turmoil if a 40ton truck existed that did 3000mls to the gallon of diesel.
This is the only reason why we have emissions targets that get ever more difficult to achieve.
So can someone clarify what ad blue is and it’s uses please?Thanks.
Bking:
Thought I would try a few experiments with add blue.Got a few litres and have put some into jars.Stuck steel,aluminium,copper,brass,rubber and plastic in them to see if there is any reaction with the liquid.
Also made up some 3X strength and put the same materials in it.
So far after 48 hours nothing even the “O” ring has not shown any ill effects.
Will leave it in for a couple of weeks.
But if you boil off the water the Urea crystals are like bloody concrete and even boiling water takes a while to dissolve it.
Hi Bking,
I’ve had a look at several MSDS’s for ad-blue.
Ad-blu is a slightly corrosive substance and has a pH of 10 (which makes it an alkali.)

In the form presented for carriage, ad-blu is not classified as a dangerous substance for transport by the UN, ADR, IMDG, ADN, RID or IATA, but there are some hazards and precautions noted on the MSDS’s.

Suzuki screws and bolts are made from cheese, not sure if Adblu attacks mature Caerphilly
The two viable alternatives at the moment are SCR and EGR. EGR cools the combustion chamber, SCR cools the catalyst, both systems reduce the emissions.
How about we use Methanol again, it is fine for speedway, grasstrack and monster truck racing. The engines run cooler and the emissions are almost zero. It is sustainable and much safer than petrol, has a slightly lower flash point to diesel and is cheap to produce.
Adblue is a chemically produced mixture of 30% urea and the rest is water, it is injected into the catalyser where it converts nitrous oxide into nitrogen and water.
Contrary to popular belief it isn’t pig or cow ■■■■ and ■■■■■■■ into the adblue tank if you run out wont work!

Pig ■■■■ is corrosive and it doesn’t have a UN number, it is also used to keep aircraft runways clear of ice 
Adblue freezes at -11°c

I work as a driver for one of the big chemical companies that make and supply AdBlue and often get asked what it is, whats it do and whats it made of??. Everyone thinks its pig ■■■■ but its urea is a man made by-product of animal urine. I mean, if it was pig pee, it would be interesting to see how they collected it. The other product mixed with AdBlue is demineralised water. AdBlue is a corrosive product and has to be transported in certain tanks, but due to its such low level of corrosiveness it falls out of scope of ADR regs and vus doesn’t fall into any category. They do warn against drinking it, for obvious reasons and it is sticky if you get it on your skin. Now I have heard untold ammount of stories of drivers peeing into the tanks when they’ve run out and its worked, but being one of the first company’s to produce and supply this stuff, I’ve heard it all and now take these stories witha pinch of salt.
who do you work for, think one of the first was Yara
Keep us updated on your experiments pal.
I have been in the situation once where i was down to reserve in adblue tank and would not have enough to complete my trip, and nowhere to get any on the card, but I did have access to a hosepipe… so put enough water in to take the tank to a reasonable level to finish the run… No problems , no warming lights, no drop in performance… filled up with adblue at end of trip… used same vehicle again several times without any problems…

There was some talk in the early days about the Adblu dosing pump seizing up if it ran dry, so given the same situation. I would probably do the same. So in that respect water or ■■■■ may turn off the warning lights, after all Adblu is 70% water.

Where are certain members on here getting their info about EGR and SCR from?
EGR,correctly said earlier does stand for Exhaust Gas Recirculation,but this certainly does not cool combustion chambers or cylinders,this system allows a small amount of exhaust gas back into the induction side of the engine,but this is to allow the engine to reach it’s normal operating temperature much more quickly,thus reducing the emissions from cold start sooner.
As for SCR,this system uses Ad Blu injected into the exhaust system to further reduce emissions,and has no cooling effect whatsoever!
Personally,i think Ad Blu is an expensive and totally un-necessary extra put on trucks in the name of so called enviromental protection.
■■■■■■■ in the ad blu tank has got to be better than all over the floor at the services/lay by/side of the road/on a bay etc.

EGR does lower the combustion chamber temperature and pressure and allows the fuel to burn more efficiently thus reducing NOx
SCR doesn’t work until the catalyst temperature is between 320°c and 340°c. If it is cooler it wont reduce the NOx, if it is higher the Urea solutions turns to Ammonia too quickly, before it hits the spot.
