The future emission limits for gasoline fuelled passenger cars require more and more efficient exhaust gas aftertreatment devices - the catalytic converter being one essential part of the complex system design. The present paper summarizes the results of several basic research programs putting major emphasis on the application of highly sophisticated three-way catalyst technologies being taylored for the utilization on ultra thin-wall ceramic substrates.In the first part of the investigation the following effects were examined in detail: The resulting optimized washcoat system was tested in the second part of the investigation on a EU IV calibrated vehicle comparing a state-of-the-art 400 cpsi/6.5 mil ceramic substrate with different types of ultra thin-wall substrates (UTWS) up to 1200 cpsi/2.5 mil. Furthermore, in case of 900 cpsi/2.5 mil two different PGM-loadings were investigated.The data of the vehicle study confirmed that UTWS in combination with tailor-made coating technologies can offer a big potential to further optimize the converter performance.
