Cummins has sold 114,000 SCR-equipped engines

Sarah Jin - 26 July 2011

Cummins had sold and delivered 114,000 Selective Catalytic Reduction (SCR) equipped engines to customers across the US by May 2011, according to its comments on the Environmental Protection Agency's draft guidance on SCR technology.

Robert Jorgensen, Executive Director of Product Environmental Management at Cummins, said:

"The Cummins 15-liter ISX engine with SCR has up to 6% better fuel economy than the 2007 ISX without SCR. Consider the typical example of a truck that runs 120,000 miles per year and gets six miles per gallon. With a 6% improvement in fuel economy, the customer will save 1,132 gallons of fuel per year. For diesel fuel at $3.50 per gallon, Diesel Exhaust Fluid (DEF) at $2.50 per gallon, and DEF consumption at 2.5% of diesel fuel, the cost savings per year is $2,873. The amount of carbon dioxide (CO2) saved by the more efficient SCR engine is 11.45 metric tons per year," he added.

Cummins had also sold 300,000 SCR systems and 50,000 SCR-equipped engines to the European markets prior to 2010.
