摘要： A target value of an engine load ratio is calculated. A target throttle opening required for making the actual engine load ratio equal to the target engine load ratio is calculated on the basis of an intake pipe pressure which is a pressure in the intake passage downstream of the throttle valve. It is judged whether the target throttle opening can be realized by a step motor. A final target throttle opening is set to a maximum or minimum throttle opening which can be realized by the step motor when it is judged that the calculated target throttle opening cannot be realized by the step motor. The step motor drives the throttle valve so that the actual throttle opening is made equal to the final target throttle opening, and the intake pipe pressure is estimated on the basis of the final target throttle opening.

摘要： A target value of an engine load ratio is calculated. A target throttle opening required for making the actual engine load ratio equal to the target engine load ratio is calculated on the basis of an intake pipe pressure which is a pressure in the intake passage downstream of the throttle valve. A convergent throttle opening, which is a throttle opening to which the actual throttle opening converges assuming that the target intake air amount is kept at the calculated target intake air amount, is calculated. A final target throttle opening is set to the target throttle opening when the engine transient operation is in process, and to the convergent throttle opening when the engine steady operation is in process. Then, the throttle valve is driven so that the actual throttle opening is made equal to the final target throttle valve.

摘要： An intake passage upstream of a throttle valve is divided into a plurality of intake divided-flow conduits, and air flow meters are arranged in the respective intake divided-flow conduits. The throttle opening is obtained, and a throttle valve passing-through air amount, which is an amount of air passing through the throttle valve, is calculated on the basis of the throttle opening. Each air flow meter-detecting intake air amount, which is an intake air amount to be detected by the air flow meter, assuming that air flows through each intake divided-flow conduit by a part of the throttle valve passing-through air amount, the part being determined by a divided-flow ratio of the corresponding intake divided-flow conduit, is estimated, and a total value of the estimated air flow meter-detecting intake air amounts is then estimated. The engine is controlled on the basis of the total air flow meter-detecting intake air amount.

摘要： A control device for an internal combustion engine comprises an air flow meter arranged in the intake passage. The air flow meter includes a main passage and a bypass passage and detects a flow rate of air flowing through the bypass passage to detect a flow rate of air flowing through an intake passage. A current intake air flow rate is calculated based on a current throttle opening. When the rapid acceleration of the engine is in process, an air flow meter-detecting intake air flow rate, assuming that air flows through the intake passage at the current intake air flow rate, is estimated considering the pressure loss of the bypass passage of the air flow meter. When an operation other than the rapid acceleration is in process, it is estimated ignoring the pressure loss. The fuel injection amount is calculated from the estimated air flow meter-detecting intake air flow rate.

摘要： A control apparatus of an internal combustion engine is able to effectively suppress vibration occurring upon acceleration of a motor vehicle due to an increase in the torque generated by the engine. The apparatus controls the ignition timing in accordance with variations in the acceleration of the motor vehicle, so as to variably control the torque generated by the engine. Upon the start of variable torque control, a controller controls the opening amount of the throttle valve to be larger than the opening amount originally determined depending upon the current operating conditions of the engine. As a result, the generated torque is allowed to be larger than the normally generated torque during variable torque control, and vibration upon acceleration can be effectively suppressed.

摘要： An air-fuel ratio control apparatus of an internal combustion engine is provided which enables highly accurate calibration of an air-fuel feedback correction value to be completed in a short time, thus avoiding adverse influences on the emissions. The engine load is fixed when the air-fuel ratio or purge concentration is calibrated from the behavior of the air-fuel ratio feedback correction value. Thus, no change is observed in the engine load even if the driver operates the accelerator pedal to adjust the accelerator pedal position so as to change the required torque, and the air-fuel ratio of the air-fuel mixture is stabilized. Accordingly, air-fuel ratio calibration or purge concentration calibration can be promptly accomplished with high accuracy. Furthermore, while the engine load is being adjusted, the output torque is controlled in accordance with the required torque by adjusting the ignition timing. Thus, the required torque can be sufficiently reflected by the output torque even when calibration is carried out with the engine load fixed.
摘要翻译：提供了一种内燃机的空燃比控制装置，其能够在短时间内高精度地校准要完成的空燃比反馈校正值，从而避免对排放物的不利影响。当从空燃比反馈校正值的行为校正空燃比或吹扫浓度时，发动机负荷是固定的。因此，即使驾驶员操作加速器踏板来调节加速器踏板位置以改变所需扭矩，发动机负载也不会发生变化，并且空气 - 燃料混合物的空燃比稳定。因此，可以高精度地迅速地实现空燃比校准或吹扫浓度校准。此外，在调整发动机负荷的同时，通过调整点火正时，根据所需转矩来控制输出转矩。因此，即使在发动机负载固定的情况下进行校准，也能够通过输出转矩足够地反映要求的转矩。
