摘要： An exhaust cleaning filter for collecting particulate matter contained in exhaust gas and suitable for being disposed in an exhaust passage of an internal combustion engine is provided with: an exhaust gas inflow passage and an exhaust gas outflow passage disposed in alternating fashion; and a porous partition wall for setting the exhaust gas inflow passage and the exhaust gas outflow passage at a distance from each other. A small pore region is sectioned off on the upstream side of the partition wall and a large pore region is sectioned off on the downstream side of the partition wall. The average pore diameter of the partition wall in the large pore region is set to be greater than the average pore diameter of the partition wall in the small pore region, and is set so that ash contained in the exhaust gas is able to pass through the partition wall. The exhaust purification filter is provided with a promoting member for promoting the passing of exhaust gas that has flowed into the exhaust gas inflow passage, through the partition wall in the small pore region, and promoting inflow into the exhaust gas outflow passage.

摘要： An exhaust gas purification filter that is suitable for arrangement in an exhaust passage of an internal combustion engine and for collecting particulate matter contained in exhaust gas, comprises: exhaust gas inflow passages and exhaust gas outflow passages that are arranged alternately; and porous partitions that separate the exhaust gas inflow passages and the exhaust gas outflow passages from each other. Each of the partitions is divided into a coated zone in which a surface of a partition base is coated with a coating layer having a smaller average pore diameter than an average pore diameter of the partition base and a non-coated zone that is located on a downstream side of the coated zone and in which a surface of the partition base is not coated with the coating layer. A pore diameter of the partitions is set such that ash contained in the exhaust gas is able to pass through the partitions in the non-coated zone. A passage resistance of a partition portion located in the coated zone, the passage resistance being in a thickness direction of the partition portion located in the coated zone, is lower than a passage resistance of a partition portion located in the non-coated zone, the passage resistance being in a thickness direction of the partition portion located in the non-coated zone.
