摘要： A NOx amount capable of being absorbed by a criteria catalyst as a boundary between degradation and normality is supplied to a NOx storage reduction catalyst and thereafter, a reducer amount corresponding to the NOx amount is supplied by a rich spike operation. Degradation of the NOx catalyst is determined based upon the output of the NOx sensor at this time. Since the degradation of the NOx catalyst is determined only by a magnitude of the NOx sensor output, the degradation diagnosis can be performed with high precision. While the catalyst is normal, the excessive reducers are not supplied and therefore, deterioration of the fuel consumption can be prevented.

摘要： An air-fuel ratio imbalance among cylinders determining apparatus according to the present invention obtains an output Vabyfs of an air-fuel ratio sensor disposed at a portion downstream of an exhaust gas aggregated portion of an exhaust gas passage, and obtains a second-order differential value d2AF (a change rate of a change rate of a detected air-fuel ratio abyfs) of a detected air-fuel ratio abyfs represented by the air-fuel ratio sensor output Vabyfs. The imbalance determining apparatus determines that an air-fuel ratio imbalance state among cylinders is occurring when a detected air-fuel ratio second-order differential corresponding value (for example, a second-order differential value d2AF per se) obtained in accordance with the second-order differential value d2AF is larger than a first threshold value.

摘要： The fact that “with respect to a process in which the output value of a downstream air-fuel ratio sensor (sensor output value) is inverted from the minimum output value to the maximum output value during execution of an active control, the local maximum and minimum values of the secondary differential value of the sensor output value is widely affected by the size of the response delay of the downstream air-fuel ratio sensor and the size of the degree of the degradation of the three-way catalyst” is utilized. By preliminarily acquiring and memorizing, as maps, these relations obtained through an experiment, and applying the “local maximum and minimum values of the secondary differential value of the sensor output value” calculated from the transition of the sensor output value acquired during execution of the active control to the maps, the response delay (time constant) of the downstream air-fuel ratio sensor is acquired.

摘要： The determination of deterioration of a NOx storage reduction catalyst (4) is carried out more accurately. When a reducing agent is supplied from a supply device (5) to the NOx catalyst (4), a first supply of the reducing agent and a second supply of the reducing agent are carried out in a sequential manner by adjusting an amount of the reducing agent in such a manner that an air fuel ratio of the exhaust gas becomes a predetermined rich air fuel ratio, and a determination whether or not the NOx catalyst (4) has deteriorated is made based on a detected value of a detection device (8), which detects NH3 in the exhaust gas at the downstream side of the NOx catalyst (4), after a predetermined period of time has elapsed from the start of the first supply of the reducing agent, and after the start of the second supply of the reducing agent.

摘要： In a fuel injection system of an internal combustion engine in which a first fuel, which has a property to inhibit the adsorption of exhaust gas components by an exhaust gas purification catalyst, and the second fuel, which has a property not to inhibit the adsorption of the exhaust gas components by the exhaust gas purification catalyst, are able to be selectively used, the present invention has a task to decrease an amount of consumption of the second fuel in a suitable manner. In order to solve this task, the fuel injection system of an internal combustion engine according the present invention is constructed such that the second fuel is first supplied to the internal combustion engine when the exhaust gas purification catalyst is in a cold state, and a change from the second fuel to the first fuel is then made before the exhaust gas purification catalyst subsequently rises in temperature to an activation temperature thereof.

摘要： An inter-cylinder air-fuel ratio imbalance determination apparatus (determination apparatus) according to the present invention obtains, based on the output value of the air-fuel ratio sensor, an imbalance determination parameter which becomes larger as an air-fuel ratio fluctuation of an exhaust gas passing through a position at which the air-fuel ratio sensor is disposed becomes larger, during a parameter obtaining period. The determination apparatus energizes the heater of the air-fuel ratio sensor in such a manner that a temperature of the air-fuel ratio element during the parameter obtaining period is higher than a temperature of the air-fuel ratio element during a period other than the parameter obtaining period. Accordingly, the imbalance determination parameter is obtained while the responsiveness of the air-fuel ratio sensor is high, and thus, the inter-cylinder air-fuel-ratio imbalance determination having a high accuracy can be made.

摘要： An exhaust passage (15) of an internal-combustion engine (10) includes a selective reduction NOx catalyst (34) and an after-catalyst NOx sensor (50) for detecting a NOx concentration Cr at the downstream thereof. Reducing agent is selectively added from an addition valve (40) to the NOx catalyst. A NOx concentration Ce at the upstream side of the NOx catalyst is detected or estimated. NOx concentrations Cr and Ce before and after the NOx catalyst, which were detected or estimated during the stoppage of an addition of the reducing agent, are compared to each other to thereby determine an abnormality of the after-catalyst NOx sensor (50). An abnormality diagnosis is executed while the addition of reducing agent is being stopped to remove an influence by the NOx catalyst.

摘要： An air-fuel ratio imbalance among cylinders determining apparatus according to the present invention comprises an air-fuel ratio sensor having a protective cover and an air-fuel ratio detection element accommodated in the protective cover, and imbalance determining means. The imbalance determining means obtains a detected air-fuel ratio abyfs based on an output Vabyfs of the air-fuel ratio sensor every elapse of a constant sampling time ts, and obtains, as an indicating amount of air-fuel ratio change rate, a difference (detected air-fuel ratio change rate ΔAF) between a present detected air-fuel ratio abyfs which is newly detected and a previous air-fuel ratio abyfsold which was detected the sampling time ts ago, an average of the detected air-fuel ratio change rate ΔAF, and the like. The imbalance determining means determines that the air-fuel ratio imbalance among cylinders state is occurring, when a magnitude of the indicating amount of air-fuel ratio change rate is larger than an imbalance determination threshold.
