THREE-WAY CATALYTIC CONVERTER

摘要

The present invention relates to a three-way catalytic converter for reducing harmful exhaust components of gasoline-powered internal combustion engines, and to a corresponding method for exhaust gas purification. The catalytic converter is characterized by a particularly inhomogeneous distribution of the oxygen-storing material present.

主权项

1. A three-way catalytic converter for the reduction of harmful exhaust components in gasoline-operated internal combustion engines having one or more adjacent supporting bodies with a catalytically active coating, wherein the catalytically active coating has an inhomogeneous distribution of oxygen storing capacity in the flow direction, and wherein, on the downstream side of the catalytic converter, no oxygen storing material is present, and this area comprises a relative volume of the entire three-way catalytic converter of 5-50%.
