Company to launch oval-shaped design at 2015 Frankfurt Motor Show

Frankfurt, Germany, September 16, 2015 – Tenneco (NYSE: TEN) today introduced its oval-shaped gasoline particulate filter design at the 2015 Frankfurt Motor Show (Hall 5.1 booth A20). The filters are designed for gasoline direct injection (GDI) engines to reduce particulate emissions in compliance with the Euro 6c emissions regulations, which take effect on September 1, 2017.

GDI engines help improve fuel economy and therefore reduce CO2 emissions; however, they can have higher particulate emissions due to shorter in-cylinder fuel/air mixing times compared with multiport fuel injection engines.  Advanced fuel injection strategies are currently used to control gasoline particulate emissions in-cylinder but they are designed for a particular emission test cycle and may be less effective under real driving conditions.  Gasoline particulate filters effectively control particulate emissions under all operating conditions.

GPFs use the same type of wall-flow substrates as diesel particulate filters and can be included in the exhaust system in addition to the series three-way catalyst, or the catalyst coating can be directly applied to the filter substrate to form a four-way catalyst. Tenneco has successfully adapted its canning technology to accommodate these highly porous, fragile substrates.

 “At Tenneco, we understand the functional requirements for gasoline particulate filters based on our experience as one of the first global suppliers to offer diesel particulate filter technologies in serial production,” said Tim Jackson, executive vice president and chief technology officer, Tenneco. “With our design, engineering, systems integration and advanced manufacturing capabilities, we provide customers flexible solutions for any powertrain to meet future emissions regulations without compromising vehicle performance or durability.”

Tenneco is displaying these and other clean air technologies at its exhibit during the 2015 Frankfurt Motor Show, September 15-27, Hall 5.1, Stand A20.

Tenneco is an $8.4 billion global manufacturing company with headquarters in Lake Forest, Illinois and approximately 29,000 employees worldwide.  Tenneco is one of the world’s largest designers, manufacturers and marketers of clean air and ride performance products and systems for automotive, commercial truck, and off-highway original equipment markets, and the aftermarket.  Tenneco’s principal brand names are Monroe®, Walker®, XNOx™ and Clevite®Elastomer.
