Cummins said this week that is has built and shipped more than 20,000 heavy-duty and mid-range engines with Selective Catalytic Reduction exhaust after-treatment in conformance with EPA 2010 standards, and that by the end of August the number will top 26,000.

“Our technology experience and our own testing of the alternatives to meet the EPA 2010 emissions levels give us great confidence in our SCR solution, and we are confident that SCR is the right technology for now and for the future,” said Rich Freeland, president – engine business. “The fact that SCR is the right technology is being proven in the marketplace every day with our industry-leading engines. To date, the reliability data show that this has been our best launch ever. Our 2010 products are delivering up to 6-percent better fuel economy and lower CO2 emissions, and they are meeting the near-zero emissions levels required by EPA 2010 standards.”

Cummins met the 2010 emissions standards three years early with both the Ram Turbo Diesel and the Cummins Westport ISL G. During this time, Cummins was already producing SCR systems for Europe.

Cummins has developed and certified 13 engine families to the EPA and California Air Resources Board regulations to serve more than 60 OEM customers in 180 vehicle installations. The ISX15 Family 1 engines feature On-Board Diagnostics with improved emissions control warnings and alerts to the vehicle operator. On-Board Diagnostics will be required by the EPA and will be featured on all engine families beginning in 2013.

Cummins is based in Columbus, Ind.
