摘要： PROBLEM TO BE SOLVED: To optimally maintain the amount of exhaust emission circulating in a NOX catalyst when a reducing agent is supplied from a reducing agent supplying valve. SOLUTION: A NO x catalyst 81 is arranged in an exhaust passage of an internal combustion engine where combustion is carried out continuously under a lean air-fuel ratio. The reducing agent supplying valve 77 is arranged in the exhaust passage at the upstream of the NO x catalyst 81. When the amount of accumulated NOX in the NOX catalyst 81 should be reduced, the amount of the exhaust emission circulating in the NOX catalyst 81 is reduced positionally by changing a change-over valve from a down-flow position to an up-flow position or vice versa. The reducing agent is supplied only after the predetermined elapsed time from the time when a signal for changing the change-over valve 61 is generated. When the reducing agent is supplied, oxygen concentration in the exhaust emission exhausted from the NO X catalyst 81 is detected with an oxygen concentration sensor 48, and the elapsed time is corrected so as to conform a peak value generated in the oxygen concentration to a target value.

摘要翻译：要解决的问题：为了最佳地维持当从还原剂供给阀供给还原剂时在NO x催化剂中循环的废气排放量。解决方案：在空燃比连续进行燃烧的内燃机的排气通道中设置有NO SB SB催化剂81。还原剂供给阀77配置在NO SB SB催化剂81的上游侧的排气通路中。当NO x催化剂81中累积的NO x的量减少时，废气排放量通过将换向阀从下流位置改变到上流位置或反之亦然，在NOX催化剂81中循环的位置减小。仅在产生用于改变转换阀61的信号的时间之后的预定经过时间之后才提供还原剂。当供给还原剂时，用氧浓度传感器48检测从NO SB SB催化剂81排出的废气排放中的氧浓度，并校正经过时间，使其符合产生的峰值氧浓度达到目标值。版权所有（C）2004，JPO

摘要： PROBLEM TO BE SOLVED: To provide an exhaust emission control device capable of purifying various components included in the exhaust gas exhausted from a combustion chamber of an internal combustion engine as many as possible at a high purifying rate. SOLUTION: This device is provided with an exhaust passage joining with a common exhaust passage 20 at a downstream side after branching to two exhaust branch passages 19a and 19b, NO x catalysts 21a and 21b arranged in the respective exhaust branch passages, a particulate filter 27 arranged in the common exhaust passage on the downstream of a joining part of the exhaust branch passages, and flow rate adjusting valves 25a and 25b for adjusting an amount of the exhaust gas flowing in the respective exhaust branch passages. When an air-fuel ratio of the exhaust gas flowing in the NO x catalyst is lean, NO x in the exhaust gas is maintained. When the air-fuel ratio of the exhaust gas flowing into is rich, NO x maintained is reduced and purified by a reducing agent. Fine particles in the exhaust gas are gathered by a particulate filter and the gathered fine particles are oxidized and removed. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To reliably raise a temperature of a particulate filter, a NOx catalyst, or the whole particulate filter carrying the NOx catalyst. SOLUTION: A reducing agent feed valve 77 and an auxiliary catalyst 79 are successively disposed in an annular exhaust pipe 67 between an inflow/outflow port 65 of a control valve 61 and a particulate filter 69. When the temperature of the particulate filter 69 is raised, a reducing agent is temporarily fed from the reducing agent feed valve 77 while keeping the control valve 61 at a weak normal flow position. When the control valve 61 is kept at the weak normal flow, most of exhaust emission bypasses the particulate filter 69, and flows into the particulate filter 69 after the remaining exhaust emission of small amount passes through the auxiliary catalyst 79.

摘要： PROBLEM TO BE SOLVED: To reduce deformation of a bulkhead to close an opening of an exhaust flow passage of a particulate filter as much as possible, and to increase the strength of the particulate filter as much as possible. SOLUTION: A plurality of exhaust flow passages 3a and 3b of triangular section are formed of three porous bulkheads 2 extending substantially parallel to each other. In one exhaust flow passage 3a out of the adjacent exhaust flow passages, one end part of the bulkhead to demarcate the exhaust flow passage is deformed so as to be brought close to each other toward a tip part of these end parts, and the tip parts of the deformed bulkheads are connected to each other to at least partly close the opening of the exhaust flow passage. In the other exhaust flow passage 3b, the other end parts of the bulkhead to demarcate the exhaust flow passage are deformed so as to be brought close to each other toward tip parts of these end parts, and the tip parts of the deformed bulkheads are connected to each other to at least partly close the opening of the exhaust flow passage.
