Tenneco Gets SCR Contract For China

Posted on October 31, 2007

Tenneco Inc. announced that it has been awarded its first development contract for a completely integrated selective catalyst reduction (SCR) diesel aftertreatment system featuring its recently acquired ELIM-NOx technology. The development contract is between Tenneco’s venture in Shanghai and a major Chinese commercial vehicle engine manufacturer.

The ELIM-NOx system is designed to reduce Nitrogen Oxides (NOx) emissions by 70 to 90% using current SCR technology. Tenneco will work with the Chinese engine manufacturer to develop a complete SCR system with the ELIM-NOx injector system for truck and bus engines currently scheduled to launch in China in 2011.

"We are proud to showcase our innovative ELIM-NOx technology in the growing Chinese commercial vehicle market, an area of significant opportunity for us," said Gregg Sherrill, Tenneco Chairman and CEO. "We are well-positioned with our advanced hot-end emission control technologies and diesel aftertreatment capabilities to help engine manufacturers and OEMs worldwide meet increasingly stringent emissions standards. We look forward to supporting our newest customer to meet the upcoming Euro 4 regulations in China."

The ELIM-NOx injector system and "self-learn" monitoring device are engineered to provide rapid, uniform dispersion of urea without the use of steam or compressed air, reducing overall system lifecycle cost, Tenneco said. The "self-learn" monitoring device can significantly reduce vehicle development time and costs with the use of sensors to measure NOx, exhaust temperature and other engine parameters, the company said.

Tenneco currently operates five majority-owned joint ventures in China including emission control operations in Shanghai, Dalian (two joint ventures with JIT facilities in Changchun) and Chongqing. Volkswagen (SVW), General Motors (SGM), Chery, Brilliance, PSA (DPCA), Daimler Chrysler (Beijing Jeep), Suzuki, Nissan, Audi (FAW-VW) and Ford are among the company’s OE customers in China.
