Tenneco said at the North American Commercial Vehicle (NACV) truck show in Atlanta it would supply full aftertreatment systems for new Detroit DD5 and DD8 medium-duty engines used in the Daimler Trucks range.

The four and six cylinder engines were developed to meet and exceed rigorous demands in different global markets while complying with current and future emissions regulations.

Tenneco will supply the full aftertreatment system, which includes the complete selective catalytic reduction system featuring the supplier's proprietary mixing technology, as well as muffler and pipes. The system will be available in multiple understep, side by side and horizontal variations designed to accommodate the Daimler Trucks range which includes Mercedes-Benz trucks and buses, Setra, Freightliner, Freightliner Custom Chassis, BharatBenz, Fuso and Thomas Built Buses.

"We are pleased to partner with Daimler Trucks to support the important launch of their global engine platform for medium-duty trucks," said Tenenco CEO Brian Kesseler.

"This platform demonstrates [our] commitment to provide commercial truck customers with our most advanced aftertreatment solutions that meet the needs of the evolving global regulatory landscape, while enabling greater fuel economy and reduced CO2 emissions."

The aftertreatment system was designed and engineered at the supplier's technical centre in Edenkoben, Germany, and will be manufactured and assembled at the company's Clean Air facility in Seward, Nebraska.

Tenneco is a global supplier to Daimler, providing both Ride Performance and Clean Air technologies for many light vehicle platforms worldwide in addition to commercial truck products.
