Perovskite-type compounds for use in lean NOx traps |
| 摘要 |
An exhaust aftertreatment system for a lean-burn engine may include a lean NOX trap that comprises a catalyst material. The catalyst material may remove NOX gases from the engine-out exhaust emitted from the lean-burn engine. The catalyst material may include a NOX oxidation catalyst that comprises a perovskite compound.
