Title:
CATALYTIC CONVERTER HAVING METALLIC MONOLITH MOUNTED BY HEAT-INSULATING MAT OF REFRACTORY CERAMIC FIBER
Document Type and Number:
Japanese Patent JP3260479
Kind Code:
B2
Abstract:

PURPOSE: To prevent a metallic monolith from loosening by providing a heat- insulating mat of melt-formed refractory ceramic fibers that have been annealed to provide a Resiliency Value of at least 10 kPa.
CONSTITUTION: A catalytic converter 10 includes a metallic casing having a cylindrical canister 12 that has been welded to a pair of insulated end cones of which only an inlet end cone 14 is shown. A metallic monolith 15 is mounted in the cylindrical canister 12 by a mat 16 of annealed refractory ceramic fibers. Each of the inlet and outlet end cones has an outer metal wall 18 and an inner metal wall 19, between which is a space filled with a mat 20 of annealed, melt- formed refractory ceramic fibers. An exhaust pipe 22 has an outer metal wall 24 and an inner metal wall 25, between which is a space filled with a mat 26 of annealed, melt-formed refractory ceramic fibers. Thus, the metallic monolith can be prevented from loosening.
