SCR is the Future

The EPA 2010 emissions regulations requires 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.

Proven for EPA 2010

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: BlueTec SCR is the best option out there for 2010 EPA standards.

How SCR Works

BlueTec Selective Catalytic Reduction (SCR) treats the downstream exhaust with Diesel Exhaust Fluid (DEF), which breaks down harmlessly into nitrogen and water in a catalytic chamber.

  1. Hydrocarbon Doser adds diesel mist to help burn off particulates.

  2. The Diesel Oxidation Catalyst burns off any hydrocarbons in the exhaust gases.

  3. Burned off soot is trapped in the Diesel Particulate Filter.

  4. High levels of NOx are treated by Diesel Exhaust Fluid.

  5. Catalyst Chamber creates a chemical reaction between NOx and Diesel Exhaust Fluid.

DD15™ is Ready for SCR

We engineered the new Detroit Diesel engine platform 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.

SCR: Proven in Europe, Accepted in U.S.

SCR has been a proven technology for the past three years in Europe. In North America, SCR is the chosen technology for EPA 2010 by Detroit Diesel, Daimler Trucks North America, Volvo and Mack.

Save $480 Per Engine, Per Year

Compare to yet-to-be built high-EGR engines: BlueTec SCR allows engine to be tweaked and calibrated to improve fuel efficiency: about $480 per truck per year, according to Overdrive Magazine.

More Than Emissions: Fuel Efficiency

SCR works AFTER combustion, meaning it won't degrade performance. In fact, because the catalytic reaction happens after combustion, you can improve fuel efficiency. With SCR, you don't have to waste engine energy burning out the NOx, your Detroit Diesel engine gets improved fuel efficiency and reliability.

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 Price Stability

Diesel Exhaust Fluid (DEF), a solution with 32.5% 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.

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 the U.S. starting in 2008: Mercedes-Benz, BMW, Audi, Volkswagen, Mini, Hyundai, Kia, Jeep.
