Does Cummins have a comment on the EPA letter regarding their concerns with copper in catalysts?
We are confident that Copper Zeolite based catalyst is the best technology available for meeting the 2010 EPA standards and providing the best possible fuel efficiency for our customers. Copper Zeolite provides a much higher NOx conversion efficiency than Iron Zeolite – therefore providing better fuel economy benefits. Extensive testing by Cummins clearly demonstrates there is no reason for concern. We have shared our data with the EPA and further testing is continuing. Based on what we have reviewed to date and the additional test results, both EPA and Cummins believe we will be in a position to move ahead on the certification process later this year.
