Description
Summary:As regulations on exhaust gas become stricter, it is desirable that catalytic converters be mounted directly under the engine. Accordingly, in order to improve the reliability of the alumina mat specifications under dynamic load conditions, the compatibility between the vibration conditions and the alumina mat specifications was examined. Through this examination, it was found out that the compatibility could be adjusted by vibration load applied per alumina mat regardless of the shape of the catalytic carrier. Further, it was found that the fatigue life of the alumina mat complies with that of the ceramic materials.
