Exhaust gas purification device and exhaust gas purification method for internal combustion engine |
| abstract |
To suppress deterioration of exhaust emission when HC and NOx flow out of an adsorbent disposed in an exhaust passage of an internal combustion engine. An exhaust gas purifying apparatus for an internal combustion engine is disposed in an exhaust passage of an internal combustion engine and adsorbs HC and NOx in exhaust gas. , A catalyst 24 that purifies HC and NOx, an air-fuel ratio controller 31 that controls the air-fuel ratio of exhaust gas discharged from the engine body of the internal combustion engine to the exhaust passage, and a temperature that calculates the temperature of the adsorbent. And a calculation unit 32. The desorption temperature of HC in the adsorbent is higher than the desorption temperature of NOx, and the air-fuel ratio controller sets the air-fuel ratio to the stoichiometric air-fuel ratio when the temperature of the adsorbent is near the desorption temperature of NOx. The air-fuel ratio is made leaner than the stoichiometric air-fuel ratio when the temperature of the material reaches the vicinity of the HC desorption temperature. [Selection diagram] FIG. |
