| titleOfInvention | Exhaust gas purification device for internal combustion engine |
| abstract | (57) Abstract: improving the NO X purification rate of the NO X occluding and reducing catalyst. An exhaust passage 3 of the engine 1 by placing the NO X storage reduction catalyst 7 absorbs NO X contained in the exhaust of a lean air-fuel ratio operation in the engine, the NO X storage amount of the catalyst 7 is determined in advance when it reaches the determination value, the reducing agent from the reducing agent feed nozzle 91 into the exhaust passage of the catalyst 7 upstream (diesel oil) releasing NO X from the catalyst 7 by jetting, to reduce and purify. The determination value becomes a low value of unpurified NO X emissions by exudation in unpurified NO X emissions, or NO X absorption by discharging from the NO X storage reduction catalyst immediately after the start of the reducing agent supply is predetermined It is set as follows. Thereby, the storage NO Since the emission of unpurified NO X due to discharge or bleeding due to an increase in the amount of X is suppressed to a low value, the overall NO X purification rate of the NO X storage reduction catalyst is greatly improved. |
