摘要： There is provided an exhaust gas purification device (22) comprising a substrate used for purifying components contained in an exhaust gas discharged from an engine. The substrate has partitions (54) which define passages (50, 51) and are formed of porous material having fine pores each having a predetermined average size. The end portions of the adjacent partitions (54) defining each of part of the passages (50, 51) of the substrate are partially connected to each other such that the end portions (52, 53) are tapered toward the outside of the substrate. The tapered end portions (52, 53) partially close the end opening of the corresponding passage and form a small hole (55, 56) defined by the tips thereof. The size of each small hole (55, 56) is smaller than the cross sectional area of the corresponding passage (50) and larger than the sizes of the fine pores of the partitions (54).

摘要： This invention relates to an exhaust gas purifying ap aratus having a particulate filter for collecting particulates in exhaust gas. This particulate filter (22) contains partition walls defining paths (50, 51) in wich exhaust gas flows. This partition wall is formed of porous material. This particulate filter (22) is created by gathering tips of the partition walls and then baking with the adjacent partition walls being in contact with each other. The adjacent partition walls are bonded together at a predetermined bonding strength if the partition walls are baked such that they are in contact. Alcording to this invention, the end portion of the particulate filter (22) has a higher strength than the predetermined bonding strength.

摘要： An estimated trapped amount (PM) that is an estimated value of an amount of particulate matter that is trapped in a particulate filter (15) arranged in an engine exhaust passage is calculated based on an engine operating state, and PM removal control is performed when the estimated trapped amount exceeds an upper limit amount. Reference temperature increase control is performed to remove the particulate matter from the particulate filter (15), and an actual temperature that is the temperature of the particulate filter (15) while the reference temperature increase control is being performed is detected. A reference temperature that is the temperature of the particulate filter (15) when it is assumed that the reference temperature increase control has been performed when the amount of particulate matter trapped in the particulate filter (15) is a reference initial trapped amount is stored in advance. The estimated trapped amount is corrected based on the actual temperature and the reference temperature.

摘要： Micropore zones ZMI are defined at upstream sides of partition walls 72 of a particulate filter and macropore zones ZMA are defined at downstream sides of partition walls. The pore size of the partition walls at the micropore zones is set so that the particulate matter and the ash can be trapped by the partition walls at the micropore zones, while the pore size of the partition walls at the macropore zones is set so that the ash can pass through the partition walls at the macropore zones. When a quantity of trapped particulate matter is smaller than a limit quantity, control for increasing gas which temporarily increases the flow rate of the gas which flows into the particulate filter in order to remove the ash from the particulate filter, is performed.

摘要： An exhaust gas purification filter includes an inflow/outflow passage through which exhaust gas flows in/out, and a partition. The outflow passage and the inflow passage is alternately arranged. The partition is configured to divide the inflow passage and the outflow passage from each other, and being porous. The partition includes a coated zone where a surface of a base of the partition is covered with a first coating layer having an average pore diameter smaller than an average pore diameter of the base, and a non-coated zone where the surface of the base is not covered with the first coating layer on a downstream side of the coated zone. The average pore diameter of the base is large enough for ash to pass through the partition, and the first coating layer is constituted by a plurality of particle groups with different average particle diameters from each other.

摘要： An exhaust gas purification filter (4) 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 (6) 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 (CZ) 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 (NCZ) 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.
