Tenneco acquires mobile emissions business of Combustion Components Associates, Inc.

Tenneco, Inc. recently announced that it has signed an agreement to acquire the mobile emissions business of Combustion Components Associates, Inc. (CCA), a manufacturer of air pollution control technologies. The acquisition enhances Tenneco's complete system integration capabilities for selective catalyst reduction (SCR) emissions control technologies designed to meet future more stringent diesel emissions regulations for passenger cars and trucks.

CCA develops emissions control solutions for customers in the transportation and power generation industries. The company has designed and manufactured a Nitrogen Oxides (NOx) emission reduction system called ELIM-NOx(TM), which is designed to reduce NOx emissions by 70 to 90 percent using SCR technology. SCR is the process of removing NOx through a chemical reaction and is considered the leading technology for helping diesel engines meet the NOx emissions standards. Customer demands for this new technology, driven by regulations, will increase in the United States, Europe and China starting in 2010 - 2012.

"This acquisition strengthens our advanced technology offering. ELIM-NOx(TM) is one of the few proven high performance systems for urea and hydrocarbon injection. Combined with the SCR technology we produce today, Tenneco can offer our customers a fully integrated emission control system to meet stringent diesel emissions regulations for NOx reduction," says Gregg Sherrill, Tenneco chairman and CEO. "This technology allows us to optimize both the performance and cost of a total aftertreatment system, providing greater value for our customers globally."

The ELIM-NOx(TM) injector system and "self-learn" monitoring device are unique. The injector system is capable of providing rapid, uniform dispersion of urea without the use of steam or compressed air, reducing overall system lifecycle cost. Tenneco believes that, with this technology, it will be the only complete emissions control system manufacturer with the capability to manufacture and integrate its own injector systems into a diesel emissions control system.

The "self-learn" monitoring device — which uses sensors to measure NOx, exhaust temperature, and other engine parameters — significantly reduces vehicle development time and cost. It is temporarily mounted on a development vehicle as it operates in normal driving conditions. This helps minimize off-line vehicle testing and calibration.

"The CCA self-learning capability is truly unique, allowing for very quick prototyping of development vehicles. We believe it will offer an extremely attractive system integration alternative for our customers, saving both time and money compared to traditional dynamometer calibration techniques," adds Tim Jackson, Tenneco's chief technology officer.

In addition to providing this innovative solution to original equipment manufacturers, Tenneco will also sell retrofit versions of the ELIM-NOx(TM) system for commercial vehicles. Later this year, the company expects to complete final validation testing for the system to be added to the EPA list of verified retrofit technologies.

Tenneco will purchase CCA's mobile emission business for approximately $16 million. The transaction is subject to customary closing conditions, including receipt of various third party approvals. Tenneco expects the transaction to close in September.
