Exhaust gas purification system for internal combustion engine |
| abstract |
In an exhaust gas purification system for an internal combustion engine having a filter and an oxidation catalyst, it is possible to suitably realize fuel oxidation with an oxidation catalyst during temperature rise processing of the filter, and to supply fuel at as low a temperature condition as possible. To do. In an exhaust purification system, an exhaust temperature flowing into an oxidation catalyst exceeds a predetermined threshold temperature determined on the basis of the cetane number of the fuel so that the temperature is lower when the cetane number of the fuel is lower than when the fuel is high. When the fuel is supplied to the exhaust gas by the fuel supply means, the temperature rise process of the filter is executed by the oxidation reaction heat of the fuel in the oxidation catalyst. If the heat generation amount per unit time in the oxidation catalyst when the temperature raising process is being executed is smaller than a predetermined value, the temperature raising process being executed is stopped, and the exhaust gas that subsequently flows into the oxidation catalyst When the temperature exceeds a new threshold temperature higher than the predetermined threshold temperature, the temperature raising process is resumed.
