Exhaust gas purification device for internal combustion engine |
| abstract |
An exhaust gas purification apparatus for an internal combustion engine includes an exhaust gas purification catalyst that purifies NO X and an aftertreatment device. Exhaust purification catalyst, to vibrate in cycles of the amplitude and a predetermined range within a determined range the concentration of hydrocarbons in advance, have a property for reducing the NO X, further, to oxidize hydrocarbons It has a function. The exhaust purification device supplies hydrocarbons to the exhaust purification catalyst and performs temperature rise control for raising the temperature of the aftertreatment device. The exhaust purification catalyst has a high purification rate range that is higher than a predetermined NO X purification rate. In the temperature rise control, the total supply amount of hydrocarbons is set, and the hydrocarbon supply cycle is set in the region of the end portion on the side where the hydrocarbon supply cycle is short in the high purification rate range. |
