摘要： PROBLEM TO BE SOLVED: To properly release NOX from a NOX absorbent. SOLUTION: The NOX absorbent for absorbing NOX in the case of a lean air/fuel ratio is arranged in an engine exhaust passage and a NOX ammonia sensor 29 is arranged it the engine exhaust passage in the downstream of the NOX absorbent 23. An extra amount of reducing agent for the release of NOX is found from a change in concentration of ammonia detected by the NOX ammonia sensor 29 when a rich air/fuel ratio is established for the release of NOX from the NOX absorbent 23.

摘要： PROBLEM TO BE SOLVED: To correctly determine degree of deterioration of NOxocclusion reduction catalyst. SOLUTION: In an exhaust passage in an internal combustion engine in which an air-fuel ratio in a combustion chamber 3 is set to be lean, NOx occlusion reduction catalyst 19 for accumulating NOx in inflow exhaust gas when the air-fuel ratio in the inflow exhaust gas is lean, and emitting the accumulated NOx for reduction when oxygen concentration in the inflow exhaust gas is lowered is disposed. When NOx is to be emitted from the NOx occlusion reduction catalyst 19, the air-fuel ratio of mixed gas to be burnt in a combustion chamber 3 is temporarily set rich. Time from when the air-fuel ratio of the exhaust gas flowing into the NOx occlusion reduction catalyst 19 turns not to be lean till when the air-fuel ratio of the exhaust gas die chased from the NOx occlusion catalyst 19 becomes rich is detected. The time is corrected based on NOx occlusion reduction catalyst temperature, intake air quantity, NOx storage quantity, etc., when the air-fuel ratio of the inflow exhaust becomes rich, and the corrected time is compared with a reference value, thereby degree of deterioration of the NOx occlusion reduction catalyst 19 is determined.

摘要： PROBLEM TO BE SOLVED: To easily judge the catalyzing ability of an exhaust emission control device. SOLUTION: Three-way catalyst 5a, 5b, a NOX storage and reduction catalyzer 7, a first air-fuel ratio sensor 31 between the three-way catalyst and the NOX storage and reduction catalyzer and a second air-fuel ratio sensor 33 on the downstream side of the NOX storage and reduction catalyzer are arranged in an exhaust passage 2 for an internal combustion engine 1. An electronic control unit(ECU) 30 changes an air-fuel ratio for the engine from lean to rich and resets it to be lean again. The ECU 30 judges the catalyzing ability of the three-way catalyst in accordance with the output of the first air-fuel ratio sensor during the change of the air-fuel ratio and the catalyzing ability of the NOX storage and reduction catalyzer in accordance with the output of the first and second air-fuel ration sensors. During once changing operation of an air-fuel ratio, the catalyzing ability of the three-way catalyst and the NOX storage and reduction catalyzer can be easily judged in accordance with only the output of the first and second air-fuel ratio sensors.

摘要： PROBLEM TO BE SOLVED: To accurately judge the degree of deterioration of a NOX storage and reduction catalyzer. SOLUTION: A NOX storage and reduction catalyzer 7 which absorbs NOX in exhaust gas when an air-fuel ratio for inflow exhaust gas exceeds a theoretical air-fuel ratio and releases absorbed NOX when an air-fuel ratio for inflow exhaust gas does not exceed the theoretical air-fuel ratio is arranged in an exhaust gas passage 2 for an internal combustion engine 1 and an air-fuel ratio sensor 33 is arranged on the downstream side thereof. An electronic control unit(ECU) 30 performs such rich spike operation as lean air-fuel ratio operation of the engine for a specified time and then rich air-fuel ratio operation of the engine for a short time to be reset to the lean air-fuel ratio operation. The ECU judges the degree of deterioration of the NOX storage and reduction catalyzer in accordance with a time for an air-fuel ratio for exhaust gas detected by the air/fuel ratio sensor 33, after the rich spike operation started, to stay near the theoretical air-fuel ratio and a reference time required for NOX newly absorbed by the NOX storage and reduction catalyzer to be released.
