FILTER FOR TREATING EXHAUST GAS AND MANUFACTURING METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a filter for treating exhaust gas with which soot is captured when an engine is started and the differential pressure rise of which after the engine is started is prevented, and to provide a method for manufacturing the filter.

SOLUTION: The filter for treating exhaust gas is used for introducing the exhaust gas flowing from an exhaust gas inlet-side gas flow passage into an adjacent outlet-side gas flow passage through an oxidation catalyst-deposited porous partition wall of the exhaust gas inlet-side gas flow passage and discharging the treated exhaust gas from the outlet-side flow passage. Inorganic particles 2 having 2-20 μm average particle size are stuck to the catalyst-deposited porous partition wall 1 of a DPF (diesel particulate filter) by 0.2-2 wt.% of the filter.
