Proven for EPA 2010
BlueTec® SCR Is the Future
The EPA 2010 emissions regulations require a 90% cut in NOx emissions. Detroit Diesel has been engineering for the past several years to use BlueTec Selective Catalytic Reduction (SCR) Technology to meet the challenge.
SCR: Cleaner, Economical, Convenient, Reliable
When you consider the full scope of your business — fuel efficiency, ease of operations, reliability, maintenance training — you'll likely come to the same conclusion we did: SCR is the best option out there for 2010 EPA standards.
To learn more about how we came to choose SCR, and why you should too, listen to this interview with our Marketing Director, Dave Siler on the Freightliner Run Smart Hour.
- SCR: 3–5% improvement in fuel efficiency
- SCR: As simple as filling a tank
- SCR: Emissions technology proven for the past four years in Europe

How BlueTec SCR Works
BlueTec SCR Technology treats downstream exhaust with Diesel Exhaust Fluid (DEF), which breaks down harmlessly into nitrogen and water in a catalytic chamber.
The engine is tuned for high peak combustion temperatures, which allows for a high NOx to Particulate Matter (PM) ratio
Hydrocarbon Doser periodically adds diesel mist to help burn off the leftover particulates
Less PM gets burned off during passive regeneration due to more efficient NOx/PM ratio
The diesel oxidation catalyst burns off any hydrocarbons and CO in the exhaust gases
Leftover soot is trapped in the DPF
High levels of NOx are exposed to DEF
In the catalyst chamber, DEF neutralizes NOx
Ammonia Catalysts transform the leftover DEF into nitrogen and water
Click on the numbers above to learn how BlueTec SCR Technology reduces emissions by treating the downstream exhaust.
More Than Emissions: Fuel Efficiency
Compare to High-EGR: BlueTec SCR Technology allows engine to be tweaked and calibrated to improve fuel efficiency: about $480 per truck per year, according to Overdrive Magazine.
Since the SCR works after combustion, your engine can run at higher NOx levels. This means it can run hotter, so you won't lose fuel efficiency to heat rejection, and there will be less particulate matter going into the DPF filter. When the particulate matter does start to add up though, you can run DPF regenerations at lower temperatures, so you burn even less fuel.
DEF Simplicity and Price Stability
DEF, made up of a chemical called urea, is already widely distributed for many other industrial and agricultural needs. The amount of DEF needed for the U.S. trucking market makes up about 0.1% of the current global capacity. To utilize DEF, it's as easy as filling up a small tank, just like your gas tank, about once a week.
- Estimated need of entire U.S. fleet: 750M gallons
- Estimated current capacity worldwide: 750B gallons
SCR: Proven in Europe, Accepted in U.S.
SCR has been a proven technology for the past four years in Europe. In North America, SCR is the chosen technology for EPA 2010 by:
- Detroit Diesel
- Daimler Trucks North America
- Volvo
- Mack
- Paccar
- Cummins (medium duty)
DD15™ is SCR-Ready
We engineered the new Detroit Diesel DD15™, thinking ahead to BlueTec SCR Technology. It's ready to be integrated. That means your maintenance team won't have to learn new a whole new engine to be ready for 2010.
More Than Emissions: Reliability
Because BlueTec SCR treats exhaust after combustion, you can calibrate the engine to reduce temperatures and pressures in many parts of the engine. The reduced stress will likely lead to increased engine and part reliability.
DEF Availability: 1,800 Locations and Counting
There are commitments for more than 1,800 locations in the U.S. to find DEF:
- Daimler Trucks North America support network
- Volvo Truck dealerships
- Mack dealerships
The reach of SCR is wider than just the trucking industry. SCR technology is being adopted by passenger cars in U.S. starting in 2008: Mercedes-Benz, BMW, Audi, Volkswagen, Mini, Hyundai, Kia, Jeep.
