American Freightways and Cummins work to recalibrate engines

Cummins Inc. has reached an agreement with American Freightways Inc., the less-than-truckload carrier, to initiate a low-NOx engine recalibration program using technology developed by Cummins. To meet its goal of reducing emissions without sacrificing engine performance or fuel economy, American Freightways is recalibrating the portion of its fleet of tractors containing 1,500 Cummins 1997 and 1998

Cummins Inc. has reached an agreement with American Freightways Inc., the less-than-truckload carrier, to initiate a low-NOx engine recalibration program using technology developed by Cummins.

To meet its goal of reducing emissions without sacrificing engine performance or fuel economy, American Freightways is recalibrating the portion of its fleet of tractors containing 1,500 Cummins 1997 and 1998 M11 and M11 Plus engines. Under this initiative, American Freightways expects to recalibrate these engines by spring of 2002.

"American Freightways has always enjoyed a reputation for going above and beyond what is required by its customers and by the EPA,” said Cummins executive director – marketing Tom Kieffer. “To their credit, they are among the first of our customers to take this step toward a cleaner environment."

The recalibrations take place at regular maintenance intervals, utilizing Cummins INSITE/ESDN software as a tool for initial recalibration, and later utilizing Cummins INSPEC software as a management tool to adjust and maintain engine parameters.

Cummins is providing American Freightways with recalibration software, as well as engine stickers for each recalibrated engine to indicate that it meets the optional low-NOx standard set by the EPA.
