EURO-V 규제 대응을 위한 TWC 성능 개선에 관한 연구

This study has been focused on minimization of the exhaust gas emissions to meet EURO-V emission standard by using CCC system configuration. The new catalysts suggested as the next generation catalysts have been Pt/Pd/Rh, Pd/Rh and Pd Only. The Characteristics of Catalyst according to the W/C and promoters have been evaluated in order to establish to the catalyst technologies for gasoline engine. The emission performances of new W/C technologies have been analyzed and evaluated with engine bench test and vehicle test. From the test results, it could be suggested the optimal data applied to catalyst design.
