Abstract:
An emissions control device for a compression ignition engine is described. The emissions control device comprises: (a) a first catalyst comprising an electrically heatable substrate and a first composition disposed on the electrically heatable substrate, wherein the first composition comprises alumina and a first platinum group metal (PGM); and (b) a second catalyst comprising a substrate and a second composition disposed on the substrate, wherein the second composition comprises alumina and a second platinum group metal (PGM); wherein the loading of the first composition is less than the loading of the second composition.
