EXHAUST EMISSION CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE, ITS MANUFACTURING METHOD AND HOLDING MATERIAL OF CARRIER FOR EXHAUST EMISSION CONTROL

摘要

PROBLEM TO BE SOLVED: To compensate deterioration of bearing pressure in a burning process of organic substance included in a non-expansive holding member using alumina fiber or the like as a matrix and to prevent deviation of a carrier installation position. SOLUTION: An expanding material expandable at comparatively low temperature is included in at least a part of the holding material 31. When forming a container material 41' by spinning work, the expanding material (vermiculite, graphite or the like) expanded by heat generated by the spinning work is included in a side facing the container material 41'. It is also favorable to include the expanding material in a side facing a carrier 11.
