Abstract
A method of using a hybrid oxidation catalyst system for remediating a lean emission from a vehicle includes the step of oxidizing the hydrocarbons and carbon monoxide in an engine emission comprising hydrocarbons, carbon monoxide, NOincluding NO and NO, and oxygen with a first catalyst. The first catalyst includes noble metal particles supported in a first ceramic layer. The method further includes oxidizing the NO with a second catalyst having base metal oxide particles supported in a second ceramic layer to form NO. The first catalyst is disposed upstream of the second catalyst and the system is capable of converting at least 10% of the amount of NO to NOat a temperature ranging from 75° C. to 225° C.
