Please refer to the following link for details about the latest in diesel engine emission control by Mercedes. The technology is called BLUETEC and they hope to take-on the last bastion in the petrol/gas world - USA - and make diesels acceptable there. Although it will be more because of rising oil prices and fuel efficiency of modern diesels that will make diesels more acceptable in America than really environment-friendly technology. The days of cheap gasoline are gone, and the world, esp. America, will have to accept diesel and other environment and pocket friendly technology - be it hybrids (Toyota Prius and Honda Insight being popular examples) or fuel cell or any other upcoming technology. But the most cost-effective solution to rising fuel prices today is modern diesel technology - that is till other technologies become more acceptable and cost-effective and most importantly are able to achieve economies of scale so as to have prices comparable to today's vehicles.
By the way, www.autointell.com is a good website for international automobile news.
The article is detailed below as well, in case the link doesn't work.
With the E 320 BLUETEC, Mercedes-Benz is launching a new era in diesel technology in USA
Spiraling fuel prices have also increased the demand for economical, clean cars in the USA. Mercedes-Benz is launching the new E 320 BLUETEC on October 15, timed to coincide with the introduction of low-sulphur diesel fuel in the USA. This model is also one of the most economical vehicles in its class and is regarded by experts as the pioneer of a new diesel era.
“BLUETEC power is about to win many friends in North America as soon as US customers get behind the wheel of a car like the E 320 BLUETEC”, says Dr Thomas Weber. “Our 208 hp three-litre V6 develops eight-cylinder-like torque of 400 pounds feet (540 Nm) combined with the sort of economy you get from a four-cylinder engine in everyday use.” The combined consumption of just 6.7 l/ 100 km (35 miles per US gallon) provides a range of 700 miles (around 1200 km) without having to refuel.
Ultra-modern diesel vehicles provide their owners with assured, clean and economical driving pleasure and can potentially – given a sufficiently large uptake – make national economies less dependent on oil imports. An EPA study dating back to 2004 confirmed the enormous potential savings inherent in diesel. Margo Oge, Director of the Office of Transportation and Air Quality, came up with the following calculation: if just a third of the light-duty vehicles in the USA were state-of-the-art diesel vehicles, we would be looking at saving 1.4 million barrels a day, the equivalent quantity of oil the USA imports from Saudi Arabia every day.
With no end in sight to soaring fuel prices, experts predict a greater uptake of diesel around the globe. The recent J.D. Power study “Global Outlook For Diesel” forecasts that the current global diesel market share of 18 percent is set to reach around 30 percent in 2015: diesel vehicles are expected to account for over 15 percent of new registrations in North America.
Additional BLUETEC models in the USA and Europe by 2008
Against this background, Mercedes-Benz intends to systematically broaden its BLUETEC portfolio. Dr Weber: “In addition to the E 320 BLUETEC we aim to have another three BLUETEC models in the line-up as early as 2008 that meet the 50-state BIN 5 standard in the R-Class, ML-Class and the GL Class.” Following its launch in the USA, Mercedes-Benz intends to successively roll out BLUETEC in other markets. At present the technology is being adapted to European market requirements and other Mercedes Benz models.
The company’s European customers should have the option of BLUETEC in a passenger car by 2008 at the very latest. Meanwhile the Jeep Grand Cherokee BLUETEC concept is a perfect example of how other DaimlerChrysler brands can also leverage BLUETEC.
BLUETEC is a modular emission control system that reduces nitrogen oxides. Diesel engine design means nitrogen oxide is currently the only emissions constituent that exceeds the equivalent figure for a petrol unit. Mercedes-Benz has developed BLUETEC in two versions: in the E-Class an oxidation-type catalytic converter and particulate filter are combined with an improved, extremely durable NOx trap system and an additional SCR catalytic converter. The second BLUETEC version is even more efficient. Here, AdBlue, a non-toxic aqueous solution, is injected into the exhaust-gas stream, causing ammonia to be released. In the downstream SCR catalytic converter the ammonia then converts up to 80 percent of the nitrogen oxides into the harmless natural products of nitrogen and water. The specific vehicle concept and weight as well as the deNOx requirements determine which BLUETEC system is used. In principle, BLUETEC is capable of meeting the world’s most stringent exhaust emission standards.

Yup. Thats pretty much it. Its a complicated and high tech exhuast aftertreatment system only for American market.
Euro emission standards are more relaxed (for NoX) and they dont get Bluetec.

Guys ... Bluetec is the marketing name of The SCR System.. It is bascically a lab on Wheels.. You Get some ammonia from Urea(Which is stored in a separate tank andneed to fill up as you fill Diesel).. and use that to reduce NOx... So it is not like a clean burning engine.. The Engine Burns as is it.. and the exhaust is measured through Sensors.. and adequate ammonia and other chemicals required are dispensed..
Don't Be happy that Bluetec Comes with CRdi... Because of the tighter contols you need CRdi... to Run BLUETEC
BTW.. Bosch was planning to bring The SCR system to India... And The major problem is Logistics... Believe me guys.. Euro 4 is going to be intresting...
And I wanna to know who'll compell Truckers to fill some fliuid For nothing.. which smells bad..

But M-power I think Trucks In Europe have SCR and they have pumps distensing Ad- Blue with double nozzles or something...
One secret.. the system right now can't distinguish whether it is ad- blue or water.. So idf you wanna save few bucks..fill the ad- blue tank with water.. The system should be okay..I suppose...It is designed to handle acqueous stuff..Your emissions will go for a toss but engine will be fine....

So soon you'll have to pay for Diesel and the Blue stuff???? AND pay more for the car since it has to be designed to run the blue stuff?

I Think So... Steeroid.. But Think of the nice part.. It Is renewable.. Not Like Fossil fuels.. You won't run Out Of It...
That thing has its own ECU and all.. It is going to be really costly.. THe SCR Module..
