摘要： A characteristic change of a humidity sensor 19 is detected based on the transitional characteristics of output data of the humidity sensor 19 with respect to integrated moisture quantity data representative of an integrated amount of moisture that is supplied to an HG adsorbent 7 by an exhaust gas after an engine 1 has started to operate. A parameter for grasping a state of the HC adsorbent 7 is corrected. The state, such as a deteriorated state or the like, of a hydrocarbon adsorbent (HC adsorbent) is properly monitored while compensating for the effect of the characteristic change of the humidity sensor and the effect of variations of the characteristics of individual units of the humidity sensor.

摘要： A temperature sensor is disposed near an HC adsorbent in an exhaust system of an internal combustion engine. After the internal combustion engine is shut off, a deteriorated state of the HC adsorbent is evaluated based on a value of the humidity detected by a humidity sensor. The deteriorated state of the HC adsorbent is evaluated by comparing the detected value of the humidity with a threshold established depending on the temperature state near the HC adsorbent. In evaluating deteriorated state of the HC adsorbent, a change in the output characteristics of the humidity sensor depending on its temperature state is compensated for.

摘要： A humidity sensor 4 is disposed downstream of an exhaust gas purifier comprising a hydrocarbon adsorbing catalyst 2, and an air-fuel ratio sensor 5 is disposed at least downstream of the exhaust gas purifier. The hydrocarbon adsorbing ability of a hydrocarbon adsorbent of a hydrocarbon adsorbing catalyst 2 (the exhaust gas purifier) is evaluated using output data of the humidity sensor 4. The unburned gas purifying ability based on a catalytic action of the hydrocarbon adsorbing catalyst 2 is evaluated using output data of the air-fuel ratio sensor 5. Based on the evaluated results, the overall deteriorated state of the exhaust gas purifier is evaluated. The overall deteriorated state of the exhaust gas purifier which has the hydrocarbon adsorbing catalyst 2 can thus adequately be evaluated.
