摘要： A control device according to the present invention includes a plurality of arithmetic units that operate in parallel. A sensor value of the control amount is input to the first arithmetic unit in a signal transmission sequence, and a correction amount for the manipulation amount is output from the last arithmetic unit in the signal transmission sequence. The first arithmetic unit has a controller that produces an output by processing the input sensor value, and the arithmetic units other than the first arithmetic unit has a delay element that delays an input by a predetermined number of steps and a controller that produces an output by processing the delayed input.

摘要： The control system of an internal combustion engine of the present invention comprises an S/V ratio changing mechanism able to change an S/V ratio of a combustion chamber and a detection device having an output value changing in accordance with a hydrogen concentration in exhaust gas, which increases along with an increase in the S/V ratio, the internal combustion engine being controlled by the output value of the detection device. Further, the output value of the detection device or a parameter relating to operation of the internal combustion engine is corrected in accordance with the S/V ratio of the above S/V ratio changing mechanism. Due to this, even if the hydrogen concentration in the exhaust gas increases along with an increase in the S/V ratio, the internal combustion engine can be suitably controlled.

摘要： An air-fuel ratio control device includes an air-fuel ratio sensor provided upstream from a three-way catalyst, and an oxygen sensor provided downstream from the three-way catalyst. The air-fuel ratio control device controls the fuel supply amount based on the output from the air-fuel ratio sensor, and compensates for errors in the air-fuel ratio sensor by correcting the fuel supply amount based on the output from the oxygen sensor. The fuel supply correction amount is calculated based on an integral term that integrates the deviation between the output from the downstream air-fuel ratio sensor and the target air-fuel ratio. When a fuel supply adjustment control is executed, the value of the integral term in the sub-feedback control is not updated for a predetermined period after the fuel supply adjustment control ends. The actual air-fuel ratio is thus brought to the target air-fuel ratio in an appropriate manner.

摘要： In an exhaust gas purification device for an internal combustion engine, a three-way catalyst and a NO.sub.X occluding and reducing catalyst (a NORC) are disposed in the exhaust gas passage of an engine in this order from the upstream side. A first air-fuel ratio sensor is disposed in the exhaust gas passage between the three-way catalyst and the NORC, and a second air-fuel ratio sensor is disposed in the exhaust gas passage downstream of the NORC. An engine electronic control unit (ECU) changes the operating air-fuel ratio of the engine from a lean air-fuel ratio to a rich air-fuel ratio and a rich air-fuel ratio to a lean air-fuel ratio in order to evaluate the abilities of the three-way catalyst and the NORC. The ECU evaluates the catalytic abilities based on the output of the first air-fuel ratio sensor when the engine air-fuel ratio is changed. Further, the ECU evaluates the catalytic ability and the NO.sub.X absorbing capacity of the NORC based on the outputs of the first and the second air-fuel ratio sensor when the engine operating air-fuel ratio is changed. The evaluation of the abilities of both the three-way catalyst and the NORC in one successive changing operation of the engine operating air-fuel ratio is based on only the outputs of the first and the second air-fuel ratio sensor.

摘要： This invention is intended to ensure that a control device for a vehicle drive unit is capable of realizing desired torque by making the main-actuator and sub-actuator collaborate adequately while holding the interposition of the sub-actuator as low as possible. For this end, a future target of torque that is going to be output from the engine and a realization timing of the future target are taken as reservation information for reserving engine torque regulation. Next, the required period, which is required to realize the future target when a main-actuator (a throttle) is operated to regulate the torque, is computed from a current engine operating condition. Then, the operation of the main-actuator is started at the timing preceding the realization timing by the required period for realizing the future target. In parallel with that, a sub-actuator (an ignition system) is operated to cancel out a torque change induced by the operation of the main-actuator during the period from the start timing of the operation of the main-actuator to the realization timing.

摘要： A NOx occluding member that occludes NOx when the air-fuel ratio is on the fuel-lean side is disposed in an engine exhaust passage. An NOx ammonia sensor is disposed in the engine exhaust passage downstream of the NOx occluding member. A surplus amount of a reducing agent that is not used to release NOx is determined from a change in the ammonia concentration detected by the NOx ammonia sensor when the air-fuel ratio is changed to the fuel-rich side so as to release the NOx from the NOx occluding member.
