COLUMBUS, Ind. — After seven months' production of its EPA 2010 certified and compliant engines, Cummins announced that it has built and shipped more than 20,000 units.

At the end of August, the number is expected to hit 26,000. The heavy-duty and mid-range engines use selective catalytic reduction (SCR) exhaust aftertreatment to meet the EPA standards.

"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," said Rich Freeland, president of Cummins’ engine business. “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 said that it 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 (OBD) with improved emissions control warnings and alerts to the vehicle operator. OBD will be required by the EPA and will be featured on all engine families beginning in 2013, Cummins said.
