Clean Air

Clean Air Overview

Tenneco's Clean Air business group is a global leader of complete emission systems. As emissions control solutions become more complex, their components must function interdependently. Integrating mechatronics and software into a range of emissions control components and systems is one way Tenneco is working to meet the challenge of delivering innovative, cost-effective and adaptable systems.

Our proprietary technologies are designed to lower harmful emissions and enable improved vehicle performance and fuel economy. We offer aftertreatment solutions that meet increasingly stringent emission regulations.

As the demand for hybridization grows, we continue to invest in technology and utilize our deep knowledge in emissions systems packaging, combustion and thermal management, materials science and thermo-electrical energy to deliver high quality solutions for our global customers.
