Abstract

An exemplary emission treatment system for reducing gases from the exhaust of an engine includes an exhaust passage for transporting the exhaust from the engine. A selective catalytic reduction (SCR) catalyst is disposed within the passage, and an oxidation catalyst is disposed in the passage upstream of the SCR catalyst. The oxidation catalyst has noble metal, with at least 90 wt. % of the metal comprising palladium (Pd).
