摘要： An exhaust gas purifying apparatus for an internal combustion engine, including a particulate filter provided in an exhaust passage of the engine; a pressure difference sensor for detecting a pressure difference between upstream and downstream side pressures of the particulate filter; an upstream side passage, which connects the pressure difference sensor and an upstream side with respect to the particulate filter of the exhaust passage; and a downstream side passage, which connects the pressure difference sensor and a downstream side with respect to the particulate filter of the exhaust passage. An exhaust gas flow rate is calculated according to an operating condition of the engine. A characteristic of change in the pressure difference, which is detected by the pressure difference detector and corresponds to a change in the exhaust gas flow rate, is detected. An abnormality of the downstream side passage is determined based on the characteristic of change in the pressure difference.

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： A deterioration determining device for an exhaust emission reduction device which is capable of improving the accuracy of determination of deterioration of a catalyst as a target, when another catalyst is disposed upstream of the target. The deterioration determining device for determining deterioration of a downstream one of two catalysts includes an ECU. After switching the air-fuel ratio from a learn value to a rich value, the ECU calculates an upstream oxygen storage capability using respective equivalent ratios detected by two LAF sensors, calculates a correction coefficient according to the value of the capability, calculates a basic value of a downstream oxygen storage capability using equivalent ratios detected by two LAF sensors, and multiples the basic value by the correction coefficient to calculate the downstream oxygen storage capability. When this is smaller than a predetermined value, the downstream catalyst is determined to be deteriorated.

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.
