摘要： With an electronically controlled throttle type internal combustion engine, where a target opening of a throttle valve is set according to a required output of the engine, and the throttle valve is opened and closed with an actuator so as to obtain a target opening; air quantity learning for learning and correcting the target opening of the throttle valve so as to obtain a target intake air quantity is performed by comparing an intake air quantity estimated based on a detection value of the throttle valve opening and an actually detected intake air quantity, at the time of idling the engine. After completion of the air quantity learning, friction learning for learning and correcting the target opening of the throttle valve so as to obtain a target engine output is performed while feedback controlling the throttle valve opening so that the engine rotation speed approaches a target idle rotation speed, at the time of idling the engine. In this way, it is possible to effect control which makes the throttle valve opening correspond very accurately to the required engine output, over a long period of time.

摘要： A three-way catalyst (10) is provided in the exhaust passage (9) of an engine (1) which stores and releases oxygen according to the oxygen concentration in the exhaust gas. A controller (2) calculates an oxygen storage amount of the catalyst (10) by accumulating a variation rate of the oxygen storage amount of the catalyst (10) based on the oxygen amount in the exhaust gas (S3-S5). A target oxygen amount in the exhaust gas is calculated which reduces the difference of the oxygen storage amount from a target oxygen storage amount (S6). A target air/fuel ratio is calculated based on a catalyst deterioration coefficient, an exhaust gas flowrate and the target oxygen amount (S7). Due to this process, it is possible to increase the speed and accuracy of control of the oxygen storage amount of the catalyst (10) towards the target oxygen storage amount.

摘要： Fuel vapor adsorbed by activated carbon 4a in a canister 4 is introduced to an engine 10 by a manifold vacuum in an intake air passage 8, and burnt. The controller 21 estimates the fuel amount desorbed from the canister 4 during purge, using a canister model (physical model) comprising an equation which computes the adsorption amount and an equation which computes the desorption amount from the adsorption amount and purge rate. An injection pulse width output to injectors 15 is corrected to reduce an air-fuel ratio fluctuation due to the supply of this desorbed fuel to the engine 10.

摘要： A controller (6) computes the oxygen storage amount of the catalyst (3) separately as a high-speed component and a low speed component in accordance with actual characteristic. A target air-fuel ratio of an engine (1) is computed so that the oxygen storage amount is a predetermined target amount, and air-fuel ratio control of the engine (1) is performed. The oxygen storage amount is computed using an storage/release rate set according to the exhaust air-fuel ratio and catalyst temperature, etc. In this way, the oxygen storage amount of the catalyst can be precisely computed regardless of the variation in the storage/release rate which accompanies a catalyst temperature variation, and the real oxygen storage amount can therefore be controlled with a higher level of precision.

摘要： A catalyst which has an oxygen storage function is provided in the exhaust gas pipe 2 of an engine 1. The oxygen storage amount is estimated based on the output of the air/fuel ratio sensor 4 upstream of the catalyst 3. The air/fuel ratio is controlled so that the oxygen storage amount coincides with the target value. When the output of the downstream air/fuel ratio sensor 5 continuously displays a rich or a lean value for more than a determination time which is varied continuously with respect to operating conditions, deterioration in the upstream air/fuel ratio sensor 4 is detected. Thus the output of the upstream air/fuel ratio sensor 4 is corrected based on the output of the downstream air/fuel ratio sensor 5. In this manner, output fluctuations are corrected based on the deterioration of the air/fuel ratio sensor 4 upstream of the catalyst.

摘要： A catalyst 3 which has oxygen storage performance is installed in an engine exhaust passage 2, an oxygen storage amount is estimated based on the output of an upstream air-fuel ratio sensor 4 installed in the upstream of the catalyst 3, and an air-fuel ratio is controlled so that this oxygen storage amount coincides with a target value. When the output of a downstream air-fuel ratio sensor 5 has become lean or rich for longer than a fixed time, the output of the upstream air-fuel ratio sensor 4 is corrected based on the output of the downstream air-fuel ratio sensor 5 placed in the downstream of the catalyst 3. In this way, the output fluctuation due to deterioration of the air-fuel ratio sensor 4 upstream of the catalyst is corrected, and the catalyst oxygen storage amount is always precisely controlled to the target value.
