Abstract
The present disclosure is directed to an emission treatment system for oxidation of hydrocarbons and carbon monoxide and for NOabatement in an exhaust stream of a lean burn engine, the emission treatment system including a low-temperature NOadsorber (LT-NA) that includes a molecular sieve impregnated with at least one PGM component positioned in fluid communication with the exhaust stream; and an oxidation catalyst that includes a refractory metal oxide support containing manganese impregnated with platinum positioned in fluid communication with the exhaust stream, each of the LT-NA and the oxidation catalyst being disposed on a substrate. The invention provides a catalyst article combining an oxidation catalyst with a LT-NA and a related method of treatment of an exhaust gas.
