摘要： An internal combustion engine is equipped with an exhaust purification catalyst (20), an upstream air-fuel ratio sensor (40), a downstream air-fuel ratio sensor (41), and sensor heaters (56) of the upstream air-fuel ratio sensor (40) and the downstream air-fuel ratio sensor (41). A control device comprises an air-fuel ratio control part configured to control the air-fuel ratio of the exhaust gas and a heating control part configured to control the heating of the air-fuel ratio sensors. The heating control part controls the sensor heaters so that the temperature of the upstream air-fuel ratio sensor (40) becomes less than the activation temperature and so that the temperature of the downstream air-fuel ratio sensor (41) becomes the activation temperature or more while the internal combustion engine is stopped by the automatic stop function. The air-fuel ratio control part controls the exhaust air-fuel ratio based on the outputs of the two air-fuel ratio sensors during engine operation and control the air-fuel ratio temporarily based on only the output of the downstream air-fuel ratio sensor (41) after the internal combustion engine has been restarted after automatic stop.

摘要： In a limited-current type gas sensor which detects oxygen-containing gas contained in an exhaust gas of an internal combustion engine, the decomposition current value of water (H 2 O) is detected, and the existence of an abnormality of output characteristics of the limited-current type gas sensor is diagnosed based on its deviation from a reference decomposition current value of water corresponding to the concentration of water contained in the exhaust gas. Thereby, not only an oxygen sensor (air-fuel-ratio sensor), but also a NOx sensor and a SOx sensor can accurately and easily diagnose not only a remarkable abnormality of output characteristics, but also a minute abnormality thereof. In addition, the reference decomposition current value of water may be acquired based on the concentration of water detected by a separate humidity sensor or the decomposition current value of oxygen detected by the limited-current type gas sensor. In the latter case, the reference decomposition current value of water may be corrected based on a decomposition current value of oxygen detected during a fuel cut.
摘要翻译：在检测内燃机的废气中含有的含氧气体的有限电流型气体传感器中，检测出水分（H 2 O）的分解电流值，并且存在输出特性的异常有限电流型气体传感器基于其与对应于废气中所含的水的浓度的水的参考分解电流值的偏差进行诊断。因此，不仅氧传感器（空燃比传感器）以及NOx传感器和SOx传感器不仅可以准确且容易地诊断输出特性的显着异常，而且能够精确地诊断其微小异常。此外，可以基于由单独的湿度传感器检测的水的浓度或由限流型气体传感器检测的氧的分解电流值来获取水的参考分解电流值。在后一种情况下，可以基于在燃料切断期间检测到的氧的分解电流值来校正水的参考分解电流值。

摘要： A fuel injection amount is controlled so that the air-fiiel ratio of exhaust gas flowing into a catalyst (6) oscillates around a stoichiometric air-fuel ratio. When it is estimated that the level of oxygen storage capacity of the catalyst (6) is lower than a predetermined reference capacity, the amplitude of the air-fuel ratio of the exhaust gas which oscillates around the stoichiometric air-fuel ratio is reduced by controlling the fuel injection amount. The level of the oxygen storage capacity of the catalyst (6) is estimated based on the amplitude of the output signal from an oxygen sensor (14) disposed downstream of the catalyst (6).

摘要： Downstream side air-fuel ratio sensor signal based adaptive air-fuel ratio control. When the air-fuel ratio detected by the downstream side air-fuel ratio sensor is maintained lean unduly, a stuck learning control is performed to decrease a learning value to lower the air-fuel ratio. Adaptive learning value update control is performed based on the downstream side air-fuel ratio sensor signal to increase the learning value when an upstream air-fuel ratio deviates to the rich side and to decrease the learning value when the upstream air-fuel ratio deviates to the lean side. It is judged that the downstream side air-fuel ratio sensor is abnormal when a certain value or more of decrease of the learning value and a certain value or more of increase of the learning value are repeated.

摘要： An abnormality diagnosis system which can reliably detect a crack of element of an air-fuel ratio sensor. An abnormality diagnosis system of limit current type air-fuel ratio sensors (40, 41) provided in the exhaust passage of the internal combustion engine comprises a current detecting part (61) detecting an output current of an air-fuel ratio sensor and a sensor temperature control device controlling the temperature of the air-fuel ratio sensor. The abnormality diagnosis system uses the current detecting part (61) to detect the output current of the air-fuel ratio sensor when the air-fuel ratio is made the rich air-fuel ratio in the state where temperature of the air-fuel ratio is made the first temperature and when the air-fuel ratio is made the rich air-fuel ratio in the state where the temperature of the air-fuel ratio is made a second temperature higher than the first temperature. It is judged that the air-fuel ratio sensor is abnormal if the output current when the temperature of the air-fuel ratio sensor is the first temperature is larger than the output current when it is the second temperature by a predetermined value or more.
