ATLANTA, GA – Eberspaecher, best known for its climate control systems, brought its line of exhaust aftertreatment systems to the inaugural North American Commercial Vehicle show this year.

Jack Riddle, director – advanced product engineering, said Eberspaecher supplies emissions control systems to OEMs including Mack, Volvo, and Daimler – in North America and abroad. Advances in their design have made the systems more compact, assembling everything in a single canister. Positioning components closer to engine heat also supports passive regeneration of the Diesel Particulate Filter, he said.

“We are one of the largest suppliers of diesel aftertreatment systems to OEMs,” Riddle explained.

The one-box system houses the diesel oxidation converter, a diesel particulate filter, and the selective catalytic reduction (SCR) system. The systems remove harmful particulate matter and NOx from the exhaust before it’s released into the air and is how truck manufacturers comply with stringent emissions requirements.

To properly maintain the system, Riddle suggested following the OEM guidelines for scheduled maintenance. A trend he seems emerging in the future is for fabricated manifolds in commercial vehicles, which can improve the performance of the catalyst.
