Title:
主に化学量論的混合気で運転される内燃機関の排ガスからの粒子の除去
Document Type and Number:
Japanese Patent JP2010540217
Kind Code:
A
Abstract:
The catalytically active particle filter has a filter body and a catalytically active coating with two layers, where both layers contain active alumina. A layer is directly connected to flow against exhaust gas and another layer stands in direct contact with the flow against exhaust gas. The alumina is catalytically activated in former layer with palladium and latter layer contains rhodium as catalytically active component and additionally oxygen storing cerium-zircon mixed oxide. Independent claims are included for the following: (1) an exhaust-gas recycling plant for the cleaning exhaust gases; and (2) a method for cleaning the exhaust gases of combustion engines operated by predominantly stoichiometric air or fuel mixture.
