TAMPA, Fla. — Cummins has confirmed it will rely on its proven Exhaust Gas Recirculation (EGR) technology to meet the 2007 emissions standards for its heavy-duty on-highway engine lineup.

The company will pair its EGR technology with a diesel particulate filter and a crankcase ventilation system.

“For 2007, we’ll continue to deliver certified and compliant engines with the proven technology that so many successful fleets are already using to their advantage for optimal reliability, durability, fuel efficiency and low cost of ownership,” said Ed Pence, Cummins vice-president and general manager of Cummins’ Heavy-Duty Engine Business.

“At the heart of our engine system is our proven VG Turbo. And at the heart of our aftertreatment system is a DOC (Diesel Oxidation Catalyst) and diesel particulate filter,” added Steve Charlton, Cummins 2007 heavy-duty program leader. “The engine and aftertreatment perform as a system to meet the 2007 emissions standards and maintain fuel consumption comparable to current levels. System integration is a key to success in 2007, and Cummins is the only manufacturer with the key disciplines to design and manufacture it all in-house. Incremental improvements for the ISX and ISM for 2007 include an electric actuator for the VG Turbo which provides faster response and improved precision in adjusting airflow to the engine, improved EGR subsystem with a high-performance cooler, and a faster ECM (Electronic Control Module).”
