CERAMIC CATALYTIC CONVERTER

摘要

PURPOSE: To satisfactorily hold a ceramic honeycomb carrier even at a high temp. over a long time. CONSTITUTION: This ceramic catalytic converter disposed in the exhaust passage of an engine consists of a ceramic honeycomb carrier 2, a jacket 4 housing the carrier 2 and a holding member 5 made of a combination of metals different from each other in the coefft. of linear expansion and interposed between the carrier 2 and the jacket 4. At the time of temp. rise by exhaust gas, the holding member 5 absorbs the clearance between the carrier 2 and the jacket 4.
