摘要： An exhaust gas purifying apparatus for an internal combustion engine having a particulate filter provided in an exhaust system of the engine. Regeneration control is performed of burning particulates accumulated in the particulate filter. An oxygen concentration in exhaust gases flowing into the particulate filter is detected, and a flow rate of oxygen flowing into the particulate filter is calculated according to the detected oxygen concentration. An inflowing oxygen amount is calculated by integrating the oxygen flow rate when performing regeneration control. It is determined that an abnormality has occurred if the inflowing oxygen amount at a time when regeneration control ends is equal to or less than a predetermined amount.

摘要： A catalyst deterioration-determining device capable of properly performing deterioration determination, while compensating for differences in output characteristics of oxygen concentration parameter sensors disposed upstream and downstream of the catalyst, respectively. After exhaust gases flowing into the catalyst having an oxygen storage capability are switched from oxidation atmosphere to reduction atmosphere, first and second equivalent ratios indicative of oxygen concentrations, detected by first and second LAF sensors disposed upstream and downstream of the catalyst, are integrated to calculate respective first and second reducing agent amount integrated values. The integrated values are corrected by dividing them by respective average values of the first and second equivalent ratios calculated after the lapse of a predetermined time period, such that differences in gains of the first and second LAF sensors are compensated for. Then, the corrected first and second integrated values are compared for catalyst deterioration determination.

摘要： A catalyst deterioration determination device capable of determining whether or not fuel is high-sulfur fuel containing much sulfur content, and properly determining whether a catalyst is deteriorated while suppressing the frequency of execution of control for recovering the catalyst from the poisoned state to the minimum. The device determines whether or not a catalyst which purifies exhaust gases exhausted from an internal combustion engine is deteriorated based on the capacity of the catalyst for purifying exhaust gases. If it is determined that the catalyst is deteriorated, first sulfur elimination control is executed for eliminating sulfur content accumulated in the catalyst. Further, when the first sulfur elimination control is terminated, the deterioration determination of the catalyst is executed. Then, when it is determined by the deterioration determination that the catalyst is not deteriorated, it is determined that the fuel is high-sulfur fuel containing lots of sulfur content.

摘要： An air-fuel ratio control system for an internal combustion engine having a catalyst provided in an exhaust system of the engine for purifying exhaust gases and a first oxygen concentration sensor disposed upstream of the catalyst is disclosed. The air-fuel ratio control system controls an air-fuel ratio of an air-fuel mixture supplied to the engine. A degree of response deterioration of the first oxygen concentration sensor is detected. A response delay of the first oxygen concentration sensor is compensated according to the detected degree of deterioration to calculate a compensated sensor output. The air-fuel ratio is controlled so that a detected air-fuel ratio calculated from the compensated sensor output coincides with a target air-fuel ratio. A frequency characteristic of the compensation is adjusted according to the detected degree of deterioration.

摘要： Air-fuel ratio control system for an engine having a catalyst purifying exhaust gases, first oxygen sensor disposed upstream of the catalyst, and second oxygen sensor disposed downstream. Intake air flow rate is detected. An amount of oxygen flowing into the catalyst is calculated using oxygen concentration detected by the first sensor and the detected intake air flow rate. The air-fuel ratio is alternately controlled to lean and rich by comparison between the calculated oxygen amount and target values. A rich oxygen amount and a lean oxygen amount are calculated. A correction amount for correcting the first sensor output is calculated based on the rich oxygen amount, the lean oxygen amount, and an accumulated value of the detected intake air flow rate. The oxygen concentration corrected with the correction amount is used for calculating the inflowing oxygen amount, the rich operation oxygen amount, and the lean operation oxygen amount.

摘要： A deterioration detecting apparatus for a purifying catalyst in an exhaust system of an engine. A first oxygen concentration sensor is disposed upstream of the catalyst. A second oxygen concentration sensor is disposed downstream. An amount of oxygen flowing into the catalyst is calculated from the oxygen concentration detected by the first sensor and the detected intake air flow rate. A control command value of an air-fuel ratio is alternately switched between a first value corresponding to a lean air-fuel ratio and a second value corresponding to a rich air-fuel ratio according to a result of comparison between the calculated inflowing oxygen amount and target values. Excessive inflowing oxygen amounts are calculated. The target values are corrected with the excessive inflowing oxygen amount. A deterioration degree of the catalyst is detected based on an output of the second sensor when performing the switching of the control command value using the corrected target values.
