| titleOfInvention | Catalyst deterioration judgment device for internal combustion engine |
| abstract | (57) [Problem] To accurately determine the degree of deterioration of a NO X storage reduction catalyst. Air-fuel ratio in the exhaust passage of the way the engine becomes lean in A combustion chamber 3, the air-fuel ratio of the inflowing exhaust gas is stored in the NO X in the inflowing exhaust gas when the lean, the oxygen in the inflowing exhaust gas placing the NO X storage reduction catalyst 19 that reduces by releasing NO X are stored as the concentration decreases. NO X When NO X is to be released from the storage reduction catalyst 19, the air-fuel ratio of the air-fuel mixture burned in the combustion chamber 3 is temporarily made rich. After the air-fuel ratio of the exhaust gas flowing into the NO X storage reduction catalyst 19 is no longer lean, the NO X storage reduction catalyst 1 The elapsed time until the air-fuel ratio of the exhaust gas flowing out from the outlet 9 becomes rich is detected. The NO X storage reduction catalyst temperature when the air-fuel ratio of the inflowing exhaust gas becomes rich, the intake air amount, by correcting the elapsed time based on such NO X storage amount, is compared with the elapsed time after the correction and the reference value The degree of deterioration of the NO X storage reduction catalyst 19 is determined. |
