摘要： A control device for an internal combustion engine provided by the present invention is a control device which can satisfy both a requirement relating to exhaust gas performance of the internal combustion engine and a requirement relating to operation performance by properly regulating a change speed of a required air-fuel ratio, in the internal combustion engine which uses torque and an air-fuel ratio as control variables. The control device receives the requirement relating to the exhaust gas performance of the internal combustion engine, and calculates an air-fuel ratio which satisfies the requirement as a required air-fuel ratio. When a predetermined reduction condition is not satisfied, an original required air-fuel ratio is directly determined as a final required air-fuel ratio. However, when the reduction condition is satisfied, the change speed is reduced by processing the signal of the original required air-fuel ratio, and determines the required air-fuel ratio with the change speed reduced as the final required air-fuel ration. The reduction condition includes a condition that the change amount of the original required air-fuel ratio, in more detail, a change amount per calculation period is larger than a predetermined air-fuel ratio change determination value.

摘要： A control device for an internal combustion engine provided by the present invention is a control device which can enhance precision of realization of required torque while enhancing emission performance by positively changing an air-fuel ratio. The present control device generates a target air-fuel ratio by lessening a change speed of a required air-fuel ratio of an internal combustion engine. However, in a situation in which the required air-fuel ratio is made rich with return from fuel cut, lessening of the change speed of the required air-fuel ratio is stopped, and the required air-fuel ratio is directly outputted as a target air-fuel ratio. The control device calculates a target air quantity for realizing the required torque under the target air-fuel ratio. For calculation of the target air quantity, data in which relationship of torque generated by the internal combustion engine and an air quantity taken into a cylinder is fixed by being related to an air-fuel ratio can be used. The present control device manipulates an actuator for air quantity control in accordance with the target air quantity, and manipulates an actuator for fuel injection quantity control in accordance with the target air-fuel ratio.

摘要： A control device for an internal combustion engine provided by the present invention is a control device which can satisfy a requirement concerning exhaust gas performance of the internal combustion engine, a requirement concerning fuel economy performance, and a requirement concerning operation performance with an excellent balance by properly regulating a change speed of a required air-fuel ratio and an ignition timing. The present control device keeps the ignition timing at an optimal ignition timing if a predetermined permission condition is not satisfied. However, when the permission condition is satisfied, the present control device controls the ignition timing so as to compensate for a difference which occurs between torque which is estimated from an operation of an actuator for air quantity control and required torque by the ignition timing. Further, if a predetermined lessening condition is not satisfied, the present control device determines an original required air-fuel ratio directly as a final required air-fuel ratio. However, if the lessening condition is satisfied, the present control device processes a signal of the original required air-fuel ratio to lessen a change speed thereof, and determines a required air-fuel ratio the change speed of which is lessened as a final required air-fuel ratio. The permission condition includes the required air-fuel ratio changing in a rich direction, and a change amount thereof being larger than a predetermined determination reference value, and the lessening condition includes the change amount of the required air-fuel ratio being larger than a determination reference value, and the permission condition being unsatisfied.
