摘要： A control device acquires various requests concerning the performance of an internal combustion engine and sets a request-specific constraint on a control amount value. The constraint is expressed as a set of constraint index values assigned to individual control amount values, and the distribution of the constraint index values is varied in accordance with the type of a request. The control device integrates the constraint index values for each control amount value and then, in accordance with the distribution of the integrated constraint index value for a control amount, determines a limitation of the control amount. The control device determines a target control amount value within the limitation and controls the internal combustion engine in accordance with the target control amount.

摘要： A control apparatus of an internal combustion engine capable of appropriately reflecting various requests relating to the performance of the internal combustion engine. Specifically, the control device of the internal combustion engine acquires various requests relating to the performance of the internal combustion engine, and sets restricted ranges of the value of the control variable in accordance with the details of the requests. At this moment, the control device temporally changes the set restricted ranges for specific requests associated with the time integral value of the control variable rather than the instantaneous value of the control variable. Subsequently, the control device determines a final restricted range on the basis of the overlap between the restricted ranges set for each request, and determines the target value of the control variable in the final restricted range.

摘要： Disclosed is a control device that is used for an internal combustion engine and capable of making various requests concerning the performance of the internal combustion engine be reflected in a target control amount value while the requests need not be expressed in the form of a requested control amount value. The control device acquires various requests concerning the performance of the internal combustion engine and sets a request-specific constraint on a control amount value. More specifically, the control device expresses constraints to be set for control amount values as a set of constraint index values assigned to individual control amount values, and varies the distribution of the constraint index values assigned to the control amount values in accordance with the type of a request. Next, the control device integrates, for each control amount value, the constraint index values assigned to individual requests with respect to each control amount value. Then, in accordance with the distribution of the integrated constraint index value for a control amount, the control device determines a limitation of the control amount, which is defined by an upper-limit value and a lower-limit value. The control device determines a target control amount value within the determined limitation.

摘要： A catalyst degradation determining method includes the steps of: controlling an upstream-of-catalyst air-fuel ratio occurring upstream of a first catalyst to an air-fuel ratio that is rich of a stoichiometric air-fuel ratio so that first and second catalysts store oxygen up to a maximum storage amount of oxygen. The method then includes the steps of controlling the upstream-of-catalyst air-fuel ratio to a first lean air-fuel ratio until an output of a downstream-of-first-catalyst sensor indicates a lean air-fuel ratio, and then to a second lean air-fuel ratio and that has a value that is determined in accordance with an oxidizing-reducing capability index value, until a time point when an output of a downstream-of-second-catalyst air-fuel ratio sensor indicates an air-fuel ratio that is lean.

摘要： An exhaust purification apparatus for an internal combustion engine includes a catalyst unit disposed in an exhaust passage of the engine, upstream and downstream air-fuel-ratio sensors disposed upstream and downstream, respectively, of the catalyst unit, a main-feedback controller, and a sub-feedback controller. The main-feedback controller calculates a main-feedback control quantity on the basis of an output value of the upstream air-fuel-ratio sensor and a predetermined upstream-side target value, and corrects, on the basis of the main-feedback control quantity, the quantity of fuel injected by an fuel injector. The sub-feedback controller calculates a sub-feedback control quantity on the basis of an output value of the downstream air-fuel-ratio sensor and a predetermined downstream-side target value, and corrects, on the basis of the sub-feedback control quantity, the quantity of fuel injected by the fuel injector, independently of the correction of the fuel injection quantity by the main-feedback control means.
