EXHAUST PURIFICATION SYSTEM FOR INTERNAL COMBUSTION ENGINE
摘要
<p>An object of the present invention is to suppress a reduction in a NO X purification ratio accompanying filter regeneration processing in an exhaust gas purification system for an internal combustion engine that includes a filter carrying an SCR catalyst. In the present invention, the temperature of the filter is increased following completion of the filter regeneration processing by increasing the temperature of exhaust gas discharged from the internal combustion engine, and in so doing, HC adhered to the filter is removed.</p>
