Abstract: An exhaust gas purifying apparatus for an internal combustion engine having a lean NOx catalyst in an exhaust system is provided. The lean NOx catalyst traps NOx in exhaust gases when the exhaust gases are in an oxidizing state, and discharges the trapped NOx when the exhaust gases are in an reducing state. In this apparatus, an estimated trapped NOx amount which is an estimated value of an amount of NOx trapped in the lean NOx catalyst, is calculated using a neural network. Engine operating parameters indicative of an operating condition of the engine are input, and the neural network outputs at least one control parameter which is relevant to the lean NOx catalyst. A reducing process of the NOx trapped in the lean NOx catalyst is performed according to the estimated trapped NOx amount.

Abstract: A control system for an internal combustion engine, which is capable of properly controlling both the temperature of an exhaust system and the air-fuel ratio of exhaust gases even when the control range of the air-fuel ratio of a combustion air-fuel mixture is limited, thereby improving the reduction of exhaust emissions. In the control system, a demanded torque-calculating section calculates a demanded torque. A first controller calculates a target equivalent ratio such that a DeNOx catalyst temperature converges to a predetermined target temperature. A second controller calculates three feedback correction values such that an output value from an oxygen concentration sensor converges to a target output value. A third controller calculates a torque fuel injection amount for generating the combustion air-fuel mixture, a post fuel injection amount for supplying unburned fuel to a DeNOx catalyst, etc. based on five values.

Abstract: An exhaust emission control device for an internal combustion engine, capable of supplying a just enough amount of reducing agent to a selective reduction catalyst even when a NOx purification ratio of the catalyst is changed by various causes, thereby enabling a high NOx purification ratio and very low exhaust emissions to be maintained. An ECU calculates a filtered value based on a signal from an exhaust gas concentration sensor, calculates a moving average value of a product of the filtered value and a reference input, calculates a control input such that the moving average value becomes equal to 0, and adds a reference input to the control input to calculate an FB injection amount. The ECU calculates an FF injection amount with a predetermined feedforward control algorithm, and adds the FF injection amount to the FB injection amount, to thereby calculate a urea injection amount.
