A couple quick questions...
WTF is urea?
How much does it cost?
How much urea is used per oil change?
What happens when the the little urea low light comes on?
What if my daughter ignores that warning light(like every other dash warning)
Couldn't Ford call this stuff something other than Urea?
Why does Ford have to use this stuff ? Does any body else?
Will the local gas n go stock it when I need a quart?
What is Ford Thinking anyway?
The guys at Toyota are already laughing (they are probably the ones that named this crap that sounds like pus from some sort of STD infliction.)

I'm new here because I would really like a 20MPG E-350 as an RV that I can afford to drive.
Urea is exactly that, Urea - (NH2)2CO
Its used to break down the NOX emissions that diesels emit, it actually eliminates up to 99% of them...
As for how often you need to fill up the tank, those that are already on sale in europe dont need filling up until the vehicle needs its oil changed.
Its a much better system than the DPF, as you don't need to "regenerate" it, as such fuel economy is much better.

09 VW TDI's are equiped with this set -up. Ford should have went this direction with the 6.4. Hindsight is always 20/20. It looks to be the best way to go. I cant wait for Ford to bebut this truck with some common sense engineering. I am subscribed.
I remember reading a few years ago when the "Bluetec" systems from Mercedes were being review that Fed regulations had issues with the SCR system because it required user intervention, meaning if the tank went empty it wouldn't meet the requirements anymore. I think there was debate as to whether it counted as a maintenance item as plugs/wires/filters would be considered, or a user responsibility.

So will the reduction in NOX have any effect on particulates? Maybe less work for the DPF resulting in fewer regens, or am I just dreaming again?
I'm on the Heavy Duty Diesel side of things, but the technology is the same. We are going to use urea based SCR for NOx reduction, but the huge advantage is this... The amount of EGR into the engine can be reduced thereby increasing fuel economy. The resulting higher engine-out NOx is taken care of by the SCR. Also, since the engine-out exhaust gas is NOx rich, the dpf will be able to regen in the passive mode more effectively since soot oxidizes at a lower temperature in a NO2 rich environment than an O2 rich environment.
From 2010 on, all diesel powered vehicles will be required to use OBDII. When your urea tank runs out, it will derate your engine. This is a strategy being forced upon us by the EPA. If you think filling the tank with water will override this, think again. NOx sensors on the outlet of the SCR will monitor NOx levels. If the levels are higher than normal, the system will try to inject more urea to counter this. If this doesn't work, the engine will be forced into derate.
Not all OEMs will use urea. There are other technologies such as the NOx absorber catalyst that Dodge uses with the CTD. However, this system needs to be regenerated the same as a dpf which means more fuel consumption. Others may choose to use massive EGR. Again, the side effect of this is reduced fuel economy. The more you cool the combustion chamber, the more fuel you will need to make power.
