LAKE FOREST, IL — Tenneco has been awarded a contract with International Truck and Engine Corp. to supply exhaust aftertreatment systems for its entire line of medium-duty diesel vehicles with International engines, launching in 2007. The contract is Tenneco’s first in North America for diesel emission control technologies for the medium-duty commercial vehicle segment.
Tenneco will provide International’s vehicles with complete exhaust aftertreatment systems, including the diesel particulate filter (DPF) and the diesel oxidation catalyst (DOC). The new exhaust system also features air gap pipe, designed to work together with other components to provide superior thermal efficiency and help improve fuel economy, and a new hanging system which utilizes the expertise from Tenneco’s Clevite(R)Elastomer division.
Tenneco’s latest generation DPF system was designed using the company’s proprietary computational fluid dynamics and particulate ash modeling CAE (Computer Aided Engineering) technologies. The DPF not only provides an effective solution, but also has an advanced modular design that allows for easy cleaning and service every 150,000 miles. This advanced design allows International’s service technicians to remove the DPF from the vehicle in less than 10 minutes, with a simple one-bolt removal system.
The development and engineering for International Truck and Engine Corp. is being done at Tenneco’s engineering center in Grass Lake, MI, and production will take place at its exhaust manufacturing facility in Seward, NE.
Tenneco engineers work collaboratively with OEM customers to develop emissions control products and systems that enable diesel powered engines to cost effectively achieve mandated emissions levels. The company offers systems that reduce emissions, airborne and structural NVH and system costs without negatively impacting engine performance.
Tenneco’s first serial production of diesel emission control technologies in the commercial vehicle segment was last year’s launch of the DaimlerChrysler Actros in Europe. The Actros represented one of the first applications of integrating SCR (selective catalytic reduction) and exhaust silencing components in one unit for commercial vehicles.
Tenneco is also providing diesel aftertreatment technology in North America for Ford Motor Company, General Motors, DaimlerChrysler and others in support of the new 2007 EPA emissions regulations.
