Cummins offers field tests for EGR engines

| 1/14/2004

Engine maker Cummins Inc. said it would make 20 to 30 heavy-duty engines available by mid-2005 for fleets and truck makers to test as it prepares to meet the Environmental Protection Agency’s more stringent federal emissions standards coming in 2007, according to press reports.

The company said it would begin building engines in 2007 that emit 1.2 grams per brake-horsepower-hour of nitrogen oxides, an average level the EPA will allow between 2007 and 2010.

To reach that level, Cummins executives said its heavy-duty engines would be unchanged from the models it sells now, except for fine-tuning the cooled exhaust gas recirculation system and adding a particulate trap.
