초록

A ceramic honeycomb filter having improved thermal shock resistance is comprised of a ceramic honeycomb filter that has a heat absorbing material that undergoes a reversible phase change that absorbs at least in part the heat energy, for example, arising from the combustion of Diesel soot entrapped in the filter.

청구항

1. A ceramic honeycomb filter comprising a porous ceramic honeycomb body having an inlet end and outlet end connected by adjacent inlet and outlet channels that extend from the inlet end to the outlet end of the ceramic body, the inlet and outlet channels being defined by a plurality of interlaced thin gas filtering porous partition walls between the inlet and outlet channels and by ceramic plugs, such that the inlet channel has an inlet ceramic plug at the outlet end of the ceramic body and the outlet channel has an outlet ceramic plug at the inlet end ...
