Cummins Announces Intent to Meet New Fuel-Efficiency and Greenhouse Gas Standards Early

The company has worked proactively on the regulation with a wide range of stakeholders over the past several years and is already developing the clean and efficient technology that will be needed to comply.


Today's on-highway diesel engines in the United States emit 99 percent less Particulate Matter (PM) and NOx than they did 30 years ago. The company's use of Selective Catalytic Reduction (SCR) technology to meet the EPA's stringent 2010 emissions standards is a building block for the new GHG and fuel-efficiency standards. SCR not only reduces NOx to near- zero levels, but it also enables reduced fuel consumption. As a result, the Cummins 2010 Heavy-Duty and MidRange engines deliver up to 6 percent improved fuel efficiency compared with the previous models.
