A METHOD OF DESULFATION OF NOX-ADSORBERS

摘要

The present invention relates to a kind of desulfurization NOx-adsorbers (11) in diesel engine exhaust system, include the following steps: the increase of periodically temperature, the S-comprising the compounds more than decomposition temperature of the conductive matrices NOx-adsorber (11) of (18) adsorbed are by providing current to the electrically-conductive backing plate (18).
