Verwendung eines Wabenkonstruktionskörpers in einem Abgaskonvertersystem

摘要

A honeycomb structure in which a plurality of through-holes 3 extending in the axial direction are formed by a plurality of partition walls 1 and 2, wherein the plurality of partition walls 1 and 2 are constituted by a plurality of partition walls having different thicknesses and, of the plurality of partition walls having different thicknesses, those partition walls 2 having a thickness larger than the average thickness of all partition walls are provided at a higher proportion in a particular portion of the honeycomb structure whole portion having partition walls than in other portion. This honeycomb structure, and a honeycomb filter and a converter system both using the honeycomb structure satisfy recent years' requirements of improvement in warm-up property connected with purification ability and reduction in harmful substance emitted right after engine start, and yet have a sufficient mechanical strength to external pressure, a high erosion resistance and a high thermal shock resistance.
