Tenneco Lands Development Contract For Complete SCR Diesel Aftertreatment System for Chinese Engine Manufacturer
30 October 2007
Tenneco Inc. 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.
Tenneco acquired the ELIM-NOx technology as part of the purchase of the mobile emissions business of Combustion Components Associates, Inc. (CCA), a manufacturer of air pollution control technologies, earlier this year. (Earlier post.)
The ELIM-NOx system is designed to reduce NOx emissions by 70 - 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.
The new vehicles will meet the upcoming implementation of Euro-4 regulations in China.
The ELIM-NOx injector system is capable of providing rapid, uniform dispersion of urea without the use of steam or compressed air, reducing overall system lifecycle cost. A “self-learn” monitoring device significantly reduces vehicle development time and costs with the use of sensors to measure NOx, exhaust temperature and other engine parameters.
Tenneco is currently the largest emissions control supplier to automotive original equipment manufacturers in China. The company 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.
