Exhaust gas purification system for internal combustion engine |
摘要 |
<p>In a regeneration process for an exhaust gas purifier such as an NOx catalyst (101,102) or a filter (102), the activity of an oxidation catalyst (100) provided on the upstream side of the exhaust gas purifier in an exhaust passage (5) is sequentially adjusted, so that regeneration of the portions of the exhaust gas purifier is initiated sequentially (steps S103, S105, and S107). Accordingly, in a regeneration process for an exhaust gas purifier such as an NOx catalyst (101,102) or a filter (102), the regeneration process is initiated in a predetermined portion where the regeneration process is required, thereby selectively regenerating the predetermined portion of the exhaust gas purifier and improving the efficiency of the regeneration process with respect to the exhaust gas purifier.</p> |
