Daimler Goes Green with BlueTec® SCR Emissions Technology
|
|
When the EPA decided that 2010 truck emissions levels needed to be cut to near-zero, Daimler Trucks North America faced a technological choice. It could take the inexpensive route with In-Cylinder Exhaust Gas Recirculation (EGR): meeting 2010 rules but pinching fleets and their fuel economy. Alternatively, it could revolutionize the truck engine market, investing in its BlueTec® Emissions Technology for better fuel economy, longer engine life, and exceeding the 2010 emission rules.
Daimler developed the BlueTec brand of Selective Catalytic Reduction (SCR) technology to meet the challenge. This fulfilled on the promise of leveraging investments by Daimler, Detroit Diesel, Freightliner Trucks, Thomas Built Buses and Western Star.
What is BlueTec SCR?
BlueTec Emissions Technology was developed to meet the specific needs of the North American market. It relies on a proven Daimler technology, where the similar Daimler BlueTEC® emissions technology has been in use for over four years. More than 600,000 trucks worldwide currently use SCR.
At its most basic, BlueTec emissions technology:
- Is a Selective Catalytic Reduction system that cuts down on nitrogen oxides (NOx)
- Uses DEF (a substance composed of 32.5 percent urea and 67.5 percent water) to eliminate NOx
- Utilizes a simple EGR engine, Diesel Oxidation Catalyst and a Diesel Particulate Filter to meet the 2010 EPA emissions standards
DEF is currently used in both the agricultural and industrial fields, and is already available at many service chains throughout the U.S. Because it’s so widely used already, the price of DEF will continue to be stable. On-highway uses are projected to be about 2% of DEF production capacity.

BlueTec SCR vs. EGR?
| BlueTec SCR |
In-Cylinder Exhaust Gas Recirculation (EGR) |
|
Engine runs hotter, less efficiency lost to heat rejection.
|
Large loss of fuel efficiency due to additional recirculation of exhaust gasses.
|
|
Technology that has proven itself in real world testing in Europe over the past four years.
|
Unproven technology that is just a band-aid on 1970’s technology.
|
|
Up to 5% better fuel economy than EGR, and 3% more than today’s engines.
|
Loss of fuel efficiency when compared to today’s engines.
|
|
Reduces stress on many parts of the engine, thus lengthening engine life.
|
Can cause excessive wear on some engine parts thus shortening the life of your engine.
|
|
Needs only one DEF fill per 5,000-7,000 miles.
|
Necessitates regular active regenerations, which means more time spent on the side of the road, not earning.
|
|
In a recent survey, 53% of professional drivers chose SCR.
|
In the same survey, only 29% chose EGR.

Leveraging the Existing Infrastructure
Daimler Trucks North America has built a thorough network of technology and manufacturing operations that have allowed it to take the lead in producing a post-2010 emissions technology, BlueTec SCR. This infrastructure means that everything you need for an SCR-equipped engine will be there when you need it.
Existing Detroit Diesel Engines are “Wrench-Ready”
The Detroit Diesel family of engines – DD13™, DD15™ and the forthcoming DD16™ – are all “wrench-ready” for BlueTec SCR. The engines were designed to seamlessly integrate with BlueTec Emissions Technology. Technicians who’ve had two years experience on these advanced engines will not need to be retrained on a whole new engine system.
DEF Available at National and Regional Fueling Stations
In order to aid in the distribution of DEF, Daimler has teamed up with a nationwide system of petroleum distributors to leverage the existing diesel distribution network, and expand it to also carry DEF.
The first stations began to carry DEF in the fall of 2008, and by the end of 2009, all Petro, TA Travel Centers and Pilot Stopping Centers, among other regional partners, have confirmed that diesel exhaust fluid will be available at all of their branded retail locations, totaling nearly 2,500 outlets nationwide. Not to mention Freightliner and Western Star Dealers and Detroit Diesel distributors.
DEF:
- Has an established infrastructure
- Is already used for industrial and agricultural purposes
- Is supported by most major heavy-duty diesel engine manufacturers
- Requires one fill-up per 5,000-7,000 miles on the road
Furthermore, Freightliner, the leading heavy-duty truck manufacturer in North America, and Detroit Diesel, a leading manufacturer of on-highway diesel engines for the commercial truck market, are among the many transportation-related manufacturers that have endorsed SCR as their exhaust treatment system of choice.
From fuel efficiency to ease of installation, BlueTec emissions technology excels over EGR every step of the way. This proven technology is the choice of both truckers and manufacturers alike.
