Loads, Design and Durability Evaluation of Mount Systems for Ceramic Monoliths

摘要

The loads on catalytic converters and how to measure them was explained and the methods to test mount materials for practical use and the general design of the system was shown. Changes in the properties of expanding papers and limits of their use in future systems require new mount materials. Due to the high price of the usable alumina-fibermats they can only be recommended for critical applications. So the special properties of the mounting materials lead to the following fields of use: Expanding paper with high fiber content for underfloor catalysts Alumina-fibermat for systems with gas temperatures above 900℃ and or in combination with Ultra-Thin-Wall substrates For diesel applications XP with high fiber content is used, only in special applications with high accelerations, low temperatures or weak monoliths alumina-fibermat is recommended.
