TENNECO SUPPLYING KEY EMISSIONS CONTROL AND RIDE CONTROL TECHNOLOGIES FOR 2011 CHEVROLET SILVERADO AND GMC SIERRA HEAVY DUTY PICKUPS
 
Company’s technologies deliver performance and fuel economy while meeting emissions regulations
 
Lake Forest, Ill, May 5, 2010 – Tenneco Inc. (NYSE:TEN) announced that it is supplying emissions and ride control technologies for the all-new 2011 Chevrolet Silverado and GMC Sierra Heavy Duty pickup trucks, that feature clean diesel engines.
 
Tenneco is the after treatment system supplier for both the diesel and gasoline heavy-duty truck platforms. For the diesel vehicles, the company collaborated with General Motors on selective catalytic reduction technology (SCR), which will be used on these models for the first time. SCR results in significantly cleaner emissions.
 
"We’re proud to partner with GM on this new generation of clean trucks. Tenneco’s leading global position in emissions technology is helping customers like GM develop vehicles that feature emissions control systems that significantly reduce nitrogen oxide (NOx) emissions without negatively impacting fuel economy," said Gregg Sherrill, Tenneco Chairman and CEO. "Tenneco’s ride control components also help enhance the durability and ride comfort on these truck models."
 
Tenneco is supplying key components for the diesel platform’s after treatment system, including a diesel oxidation catalyst, diesel particulate filter and SCR catalyst and mixer. When combined with an 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.
 
For heavy-duty gasoline Silverados and Sierras, Tenneco is supplying components that make up the full exhaust system, everything after the manifold to the tailpipe including the y-pipe, catalytic converters and muffler assemblies.
 
Tenneco is also supplying its multi-tuned valving system on shock absorbers for GM’s heavy-duty truck platform. Multi-tuned valving enhances the vehicle ride, while reducing noise and improving durability.
 
In addition, the new Silverados and Sierras feature Tenneco’s Hydroelastic™ Body Mount technology. The Hydroelastic Body Mounts are tuned to dampen specific noise and vibration frequencies, effectively isolating the truck cab from undesirable vibrations and improving cab ride quality beyond what can be attained with conventional body mounts.
 
Tenneco will manufacture the after treatment systems at its Litchfield, Michigan; Marshall, Michigan; and South Africa facilities. The ride control components are produced at the company’s Hartwell, Georgia facility. The Hydroelastic Body Mounts are manufactured at Tenneco’s Angola, Indiana facility.
 
Tenneco is a global supplier to General Motors, providing both emissions control and ride control components and systems for light and medium-duty trucks, cross-over vehicles and passenger cars.
