SCR uses a reductant (ammonia or urea), which is injected into the exhaust gas to help reduce oxides of nitrogen (NOx) over a catalyst. Some systems also use a particulate trap to further reduce emissions. Unlike some other emissions control equipment, fitting SCR should not result in any increase in fuel consumption and by allowing the engine to be tuned for maximum economy can actually decrease fuel consumption.
Ongoing maintenance costs will involve regular replacement of the reductant, either ammonia or urea. Replacement of the ammonia gas cylinder or replenishment of the liquid ammonia/urea tank will only be required around every 9 -10,000 miles for a taxi, but will be much more frequent for a heavy vehicle. As to the choice of using urea or ammonia, it is likely that urea will be more commonly used by manufacturers as it has much lower health risks.
Clean Diesel Technologies' patented ARIS™ 2000 NOx reduction system is a low-cost urea injection system, which reduces NOx to elemental nitrogen and water vapour. At typical exhaust temperatures of 320-500°C NOx reduction is between 70% and 90%.

2010...The next SuperDuty!

Ford is currently/has been working on project "Scorpion". "Scorpion" is a in-house replacement 6.7L V8 CGI diesel slated for the 2010 SD's. Early dyno reports were showing 400 HP @ 3500 RPM and 700 FT LBS @ 1600 RPM.
This engine is also planned to get the new 6R140 6-speed auto trans.
If Ford can not make 2010 with this engine and continues to use the 6.4L it is expected that the diesel SD's will have a urea tank that needs filling for the 6.4L to meet 2010 emissions. Ford wanted to explore other options to meet 2010 emissions with the 6.4L early on and Navistar has been set on using a urea system.

Plus, rumor has it that the SuperDuty line will also receive a face-lift from the current '08.
Great NEWS PowerStrokeHD!

I read an article (magazine, not Internet
) that stated the EPA would not allow the urea injection to meet the emission standards because it requires maintenance. I guess they don't think people will maintain their vehicles.

This is good news for Ford's Sharonville Transmisson Plant who builds the 5R110 and was officially awarded the 6R140 contract. They were expected to shut down by 2010 with the end of the 5R110's production life.
