After seven months' production of its EPA 2010-certified and compliant engines, Cummins has built and shipped more than 20,000 heavy-duty and MidRange engines with Selective Catalytic Reduction (SCR) exhaust aftertreatment, and at the end of August, this number will crest at 26,000.
Cummins says it was first to certify to the EPA 2002 on-highway standards using cooled Exhaust Gas Recirculation (EGR) and added Diesel Particulate Filters (DPFs) for 2007. The company also claims it was the first to meet 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 (CARB) regulations to serve more than 60 OEM customers in 180 vehicle installations. The ISX15 Family 1 engines offer 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.
