摘要:
A packaging system for honeycomb assemblies, each including a honeycomb body and reinforcing tube held together by an interference fit or axial compression achieved by thermal expansion coefficient differences between the honeycomb body and reinforcing tube. The reinforcing tube then protects the honeycomb body, facilitating a compact and structurally-strong package.
摘要:
A composite thermal barrier and methods of applying the composite thermal barrier to a metallic surface within a combustion chamber of an engine. The composite thermal barrier includes an insulation material contained within a metallic web. The metallic web is formed on a surface within the combustion chamber of the engine.

摘要:
A composite thermal barrier and methods of applying the composite thermal barrier to a metallic surface within a combustion chamber of an engine. The composite thermal barrier includes at least one metallic support structure, a metallic skin, and an insulation material. The metallic support structure is connected to a metallic surface within the combustion chamber of the engine. The metallic skin is disposed adjacent to the metallic support structure to define a void space between the metallic skin and the metallic surface. The insulation material is contained within the volume to form the composite thermal barrier.

摘要:
An article, includes a porous ceramic honeycomb body and a housing disposed on at least one of an outer periphery of the porous ceramic honeycomb body and opposing end faces of the porous ceramic honeycomb body, wherein the housing exerts a compressive force on the porous ceramic honeycomb body in at least one of radial direction and axial direction. A method of making the article, includes heating to greater than or equal to about 200 C the housing, crimping the housing tightly around the honeycomb body while the housing is greater than or equal to about 200 C, and cooling the housing. The housing exerts a compressive force on the porous ceramic honeycomb body in at least one of radial direction and axial direction by shrinking on cooling more than the honeycomb body.
摘要:
An exhaust system includes an exhaust gas treatment article having a porous ceramic honeycomb body mounted in a housing. The exhaust gas treatment article includes a thermal barrier disposed at the outer peripheral surface of the honeycomb body, wherein the thermal barrier comprises blocked peripheral cell channels adjacent to and around the entire peripheral surface and/or a thermal barrier skin.
