Plugged honeycomb structure and method for manufacturing the same |
摘要 |
<p>In a plugged honeycomb structure 1A of the present invention, the PM-trapping layers 14 disposed on the surfaces of the partition walls 4 are extended up to inflow side end faces of the plugging portions 13 plugging outflow cells 3b so that adjacent PM-trapping layers 14 with the partition walls 4 and the plugging portion 13 therebetween are disposed so as to continue on the inflow side end faces of the plugging portions 13 and that the PM-trapping layers 14 extended up to the inflow side end faces of the plugging portions 13 form protruding portions 15 having a protrusion height corresponding with 0.1 to 2 times the length L of a side of the outflow cells 3b from the inflow side end faces of the plugging portions 13 toward the outside of the cell extension direction.</p> |
