Method and device for cleaning exhaust gases of a combustion motor

摘要

The method involves processing exhaust gas with an oxidative effective particle filter (1) and with an oxidation catalyst (2). A selective catalytic reduction (SCR) catalyst (3c) is provided for processing the exhaust gas after causing a sufficient quantity of a reducing agent over a dosing device (3b) from a reducing agent source (3a). The particle filter or its coating has metals such as platinum, palladium or rhodium. The particle filter or the oxidation catalyst is contained as nitrogen oxide storage components of oxides of the cerium, barium or strontium. An independent claim is included for an exhaust gas cleaning device with a selective catalytic reduction layer.
