A Study on the Improved Design for Automotive Catalytic Converter

자동차용 촉매장치구조의 설계개선에 관한 연구

This paper presents the effect of the component performance for mat supported monolithic cordierite ceramic underflow catalytic converters to meet the new stringent durability requirements of the world's. These objectives are met by a conceptional system approach of mat mounting material with stainless steel can(shall), and heatshield(cover), which are related to the mat erosion, a main failure pattern of the mat supported monolithic ceramic catalytic converters. In this paper we study the individual component behavior of mat erosion problem, After studying, we obtain the characterics of the component performance for automotive catalytic converters and the overall understanding of design considerations in catalytic converters.
