BRIDGEPORT, Conn. — Clean Diesel Technologies and Eaton have signed a licensing agreement that will allow them to further develop Eaton’s urea-free emissions-reducing aftertreatment system.

The companies announced Eaton will have access to Clean Diesel Technologies’ patented Advanced Reagent Injector System (ARIS) technology as part of the deal. Eaton is aiming to launch its aftertreatment system in 2011, which the company claims will reduce NOx and particulate matter without requiring diesel exhaust fluid (urea).

The company says its solution “is an integrated system that effectively meets the EPA and international regulation requirements without the on-vehicle storage, replenishment and infrastructure a urea-based system requires.”

“We are excited to enter this licensing agreement with Clean Diesel. It provides access to a key technology, which helps us provide system based solutions to reduce NOx and PM, hence making significant contributions toward emissions reduction and sustainability,” said Dimitri Kazarinoff, general manager of emerging technologies and business development with Eaton. “We are working with numerous global OEMs to provide them with NOx and PM emission reduction solutions.”
