EXHAUST PURIFICATION SYSTEM FOR INTERNAL COMBUSTION ENGINE |
摘要 |
In an exhaust gas purification system for an internal combustion engine provided with a filter supporting an SCR catalyst, the present invention is intended to suppress HC and CO from being discharged to the outside at the time of the execution of filter regeneration processing, and to carry out the filter regeneration processing in an efficient manner. In the present invention, a post-catalyst having an oxidation function is arranged in an exhaust passage at the downstream side of the filter. Then, when the temperature of the post-catalyst is lower than a predetermined activation temperature at the time the execution of the filter regeneration processing is requested, the temperature of the post-catalyst is raised by carrying out control of raising the temperature of the exhaust gas discharged from the internal combustion engine, and control of increasing the flow rate of the exhaust gas, before the execution of the filter regeneration processing. |
