Title: Exhaust gas cleaning filter
Inventor: MATSUDAIRA YASUSHI
IPC: B01J35/04
Filed: 2007-06-22
Abstract: <P>PROBLEM TO BE SOLVED: To provide an exhaust gas cleaning filter compatible with both high PM (particulate matter) collection efficiency and low pressure loss.  <P>SOLUTION: The exhaust gas cleaning filter has partition walls 11, 12 demarcating a lot of cells axially penetrating, and a sealing material having one end sealing material 13 filled in one end of given cells among the cells. Employment of a form of penetrating through some of the lot of cells suppresses increase of pressure loss due to clogging of the partition walls. Most of the exhaust gas flows as it is without passing through the partition walls by penetrating through the cells, and the exhaust gas forms turbulent flow as the form of the cell is long and slender, and repeatedly collides against the partition walls demarcating the cells. As a result, PM included in the exhaust gas is mostly collected in the partition walls of the cells while flowing through the cells. In a case of a lot of PM, PM accumulates in the cells to reduce the diameter of that part. When a suspended state is formed, collection of PM is considered to become active at that part.  <P>COPYRIGHT: (C)2009,JPO&INPIT
