摘要： A honeycomb structure comprising a plurality of columnar honeycomb segments in which two kinds of plural through-holes different in end face area are formed side by side by being surrounded by partition walls, each honeycomb segment having, at one end face, an inlet side of high opening ratio, wherein through-holes of smaller end face area are plugged and, at other end face, an outlet side of low opening ratio, and wherein through-holes of larger end face area are plugged, the plurality of honeycomb segments being bonded to each other via a bonding material in the longitudinal direction of each honeycomb segment. The Young's modulus of the bonding material when sintered is smaller than that of each honeycomb segment when sintered, and the bonded width of the bonding material is larger at the outlet side of honeycomb structure than at the inlet side is presented.

摘要： 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).
摘要翻译：由于附加填充（13），中心部分的填充百分比大于构成陶瓷过滤器的蜂窝段（2）的废气的入口端面处的周边部分的填充百分比。因此，在每个蜂窝段（2）的中心部分中的通风口（5）中累积的烟尘量相对于周边部分中的少量。这减少了中心部分的烟灰燃烧产生的热量，并且在再循环期间降低了温度上升，从而限制了陶瓷过滤器（1）的最高温度。

摘要： A ceramic filter having a honeycomb structure 10 having a large number of cells which are extending in the longitudinal direction and which are alternatively plugged on an exhaust gas G inlet side end face 10a and an exhaust gas G outlet side end face 10b to form plugged portions. The depth of the inlet side plugged portions (filler 16) is formed deeper than that of the outlet side plugged portions (filler 16). Since the exhaust gas G tends to have a decreased turbulent flow and an increased laminar flow on the inlet side, a partial accumulation of Oil-Ash on portions near an outlet side end face can be inhibited.
