Tenneco Inc. announced at the North American Commercial Vehicle (NACV) truck show in Atlanta that it will supply full aftertreatment systems for new Detroit DD5 and DD8 medium-duty engines. The four and six cylinder engines were developed to meet and exceed the rigorous demands of 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 company’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 product portfolio, 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 Brian Kesseler, CEO, Tenneco. “This platform demonstrates Tenneco’s 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 Tenneco’s technical center 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 on many light vehicle platforms globally in addition to commercial truck solutions.
