内容: | A filling percentage of a central portion is larger than that of a peripheral portion at the inlet end surface of an exhaust gas of a honeycomb segment ( 2 ) constituting a ceramic filter due to additional filling ( 13 ). Thus, an amount of soot accumulated in vents ( 5 ) in the central portion of each honeycomb segment ( 2 ) is less relative to that in the peripheral portion. This decreases a quantity of heat generated by burning of soot in the central portion, and reduces temperature rise during recycling, thus limiting the maximum temperature of the ceramic filter ( 1 ). |
