Cummins Says ’07 Units Will Get Early Testing

ngine maker Cummins Inc. said it would make 20 to 30 heavy-duty engines available by mid-2005 for fleets and truck makers to field test as it prepares to meet more stringent federal emissions standards coming in 2007.

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

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.

That means customers will already have experience with Cummins’ EGR engines, while placing test engines with customers will add knowledge of how the retuned EGR and exhaust treatment systems work, said Christine Vujovich, vice president for marketing and environmental policy.
