摘要： A particulate filter (22) for collecting particulates in the exhaust gas is comprised. The particulate filter (22) includes partitioning walls (54) for forming passages (50, 51). The partitioning walls (54) are made of a porous material. The end portions of adjacentpartitioningwalls (54) are brought close each other so as to narrow the respective passage formed by the partitioning walls (54), and the cross-sectional area of the flow path at the end region of the passage is made to be smaller than the cross- sectional area of the flow path in the remaining regions of the passage. The particulate filter (22) has an extended portion (55) which extends beyond the top ends of the partitioning walls (54) from the end surface of the particulate filter (22).

摘要： An object of the present invention is to provide a technology that enables better reduction of NOx stored in an NOx catalyst in an exhaust gas purification system for an internal combustion engine. According to the present invention, when NOx stored in an NOx catalyst is to be reduced, the air-fuel ratio of the ambient atmosphere around the NOx catalyst is decreased to a target air-fuel ratio by decreasing the air-fuel ratio of the exhaust gas discharged from the internal combustion engine. In doing so, if the temperature of the NOx catalyst is not lower than a specific temperature, the air-fuel ratio of the ambient atmosphere around the NOx catalyst is decreased to the target air-fuel ratio while bringing the combustion state into low temperature combustion (S104, S105). On the other hand, if the temperature of the NOx catalyst is lower than the specific temperature, the air-fuel ratio of the ambient atmosphere around the NOx catalyst is decreased to the target air-fuel ratio while decreasing the quantity of EGR gas in a cylinder so that the amount of generated smoke is kept within an allowable range (S107, S105).
