All-new Power Stroke engine utilizes Tenneco aftertreatment technology to meet stringent new emissions requirements
Lake Forest, Ill, November 30, 2009 – Tenneco Inc. (NYSE:TEN) today announced that it is contributing key components to the 2011 Ford F-Series Super Duty truck, including a diesel aftertreatment system that will deliver cleaner emissions that meet stricter NOx standards. The truck features Ford’s powerful new 6.7-liter Power Stroke® V-8 turbocharged diesel engine, slated to deliver greater torque, power and fuel economy while meeting 2010 emissions standards.
"Tenneco’s contribution to the Ford Super Duty reinforces our global strategy of helping customers meet new emissions requirements for on-road vehicles," said Gregg Sherrill, Tenneco Chairman and CEO. "Automakers are facing an intense regulatory period for diesel emissions and Tenneco has the proven global engineering capabilities and advanced technologies to help OEMs meet these new standards."
Tenneco collaborated with Ford engineering to integrate an aftertreatment system for the Super Duty that features a diesel oxidation catalyst, diesel particulate filter and selective catalytic reduction (SCR) catalyst. When combined with a SCR dosing system, these components work together to initiate a three-stage process that helps oxidize the diesel engine fuel, remove harmful NOx and burn off any remaining soot associated with the diesel exhaust gas. As a result, the 2011 Ford F-Series Super Duty truck complies with 2010 federal NOx emissions standards, which represents a reduction of more than 80 percent compared with the previous interim standard.
The system also includes an air gap pipe, designed to work together with other components to provide superior thermal efficiency and help improve fuel economy, as well as a new exhaust tailpipe isolator. The tailpipe isolator uses Tenneco patent-pending technology to isolate engine noise from the vehicle frame.
In addition, Tenneco is supplying its Multi-Tuned Valving system in all shocks for the Super Duty. Multi-Tuned Valving enhances the ride while reducing noise and improving durability. It provides Ford Vehicle Dynamics Engineers with an expanded range of tuning options to tailor the truck's performance in any situation.
Tenneco is also supplying Clevite® Elastomer suspension isolators for the Super Duty. The elastomer suspension isolators are tuned specifically for the Super Duty to minimize noise, with increased durability.
Tenneco will manufacture the diesel aftertreatment products at its Ligonier, Indiana facility. The shocks will be produced in Hartwell, Georgia, and the elastomer isolators are manufactured at the company’s Napoleon, Ohio and Reynosa, Mexico facilities.
Tenneco is a global supplier to Ford Motor Company, providing both exhaust and ride control components for the company’s light and medium-duty trucks as well as passenger cars.
