    摘要： There is provided an exhaust purifying system for an internal combustion engine which can achieve a function of a catalyst without deteriorating a function of ozone at the time of oxidizing and removing PM by using the ozone. The exhaust purifying system for the internal combustion engine comprises a wall-flow type particulate filter (30) for collecting particulate matter in an exhaust gas inside an exhaust passage, wherein the catalyst (38) is supported only in a part of a partition wall (37) of the particulate filter defining a passage (36) on the downstream side of the partition wall (37). In consequence, when ozone is supplied, since the ozone is introduced on the upstream side of the partition wall (37) in which the PM is collected, the ozone does not contact the catalyst supported only in the part of the partition wall defining the passage (36) on the downstream side of the partition wall. Therefore, it is prevented that the ozone is decomposed, and a PM oxidation function is achieved.

    摘要： An exhaust gas purification system provided with a trapping device (6) arranged on an engine exhaust passage and trapping particulate matter in the exhaust gas, an ozone generator (21) for generating ozone, and an ozone adsorbent (22) able to adsorb ozone, wherein at least part of the ozone generated by said ozone generator is adsorbed by said ozone adsorbent and, when particulate matter trapped on said trapping device should be removed, ozone adsorbed on the ozone adsorbent is desorbed from the ozone adsorbent and supplied to the trapping device. Due to this, it is possible to use an ozone generator with a relatively low ozone generating ability to burn off PM trapped on a filter etc. efficiently.
