METHODS AND APPARATUS FOR OPERATING AN EMISSION ABATEMENT ASSEMBLY

摘要

A diesel exhaust system includes a supply of diesel fuel. The system further includes a first reduction path having a diesel fuel-fired burner operated to partially oxidize diesel fuel supplied thereto from the supply of diesel fuel and to introduce at least one of CO and H₂ into an exhaust stream. The first reduction path further includes an oxidation catalyst and a first emissions reduction component that is configured to be regenerated by CO and H₂ in the exhaust system. An associated method is disclosed.
