Thermal Response and Emission Breakthrough of Platinum Monolithic Catalytic Converters 730569
Stringent emission standards have strongly affected the requirement for catalysts and catalytic converters. Since considerable emphasis is placed on cold-start performance, catalysts with lower density and higher oxidation activity at lower temperatures are required. Monolithic catalysts have been extensively evaluated in low-emission vehicles. This paper identifies the key phenomena associated with overtemperature and emission breakthrough problems in platinum monolithic converters.
