摘要： The apparatus of the present invention corrects a control target value of ignition timing using a multipoint learned value AGdp(n) for compensating for a change amount of the ignition timing caused by time-dependent change of the engine and a basic learned value AG(i) for compensating for a change amount of the ignition timing caused by a factor other than the aforementioned time-dependent change of the engine. In a multipoint learning range n in which the time-dependent change of the engine influences the ignition timing to a great extent, the control target is corrected using the multipoint learned value AGdp(n) and the basic learned value AG(i). In ranges other than the multipoint learning range n, the control target is corrected using only the basic learned value AG(i). Normally, only the learning of the multipoint learned value AGdp(n) is permitted in the multipoint learning range n, and only the learning of the basic learned value AG(i) is permitted in the ranges other than the multipoint learning range n. When it is determined that there is a possibility that fuel has been fed to a fuel tank, the learning of the multipoint learned value AGdp(n) is prohibited for a subsequent predetermined period (if NO in step S103 or step S104).
摘要翻译：本发明的装置使用多点学习值AGdp（n）来校正点火正时的控制目标值，用于补偿由发动机的时间变化引起的点火正时变化量和基本学习值AG（i ），用于补偿由除了上述发动机的时间变化之外的因素引起的点火正时变化量。在发动机的时间相关变化很大程度上影响点火正时的多点学习范围n中，使用多点学习值AGdp（n）和基本学习值AG（i）来校正控制对象。在多点学习范围n以外的范围内，仅使用基本学习值AG（i）来校正控制对象。通常，在多点学习范围n中仅允许多点学习值AGdp（n）的学习，并且在除了多点学习范围n以外的范围内仅允许基本学习值AG（i）的学习。当确定燃料已经被供给到燃料箱的可能性时，多个学习值AGdp（n）的学习在随后的预定时间段被禁止（如果在步骤S103或步骤S104中为否）。

摘要： Upon satisfaction of an idle learning condition, the internal combustion engine system of the invention successively performs learning of an idle control amount and learning of a most delayed angle control amount in this sequence. Upon satisfaction of a most delayed angle learning condition, on the other hand, the internal combustion engine system successively performs learning of the most delayed angle control amount and learning of the idle control amount in this sequence. This arrangement effectively reduces the total time required for completion of learning both the idle control amount and the most delayed angle control amount, compared with the conventional procedure of individually learning only one control amount corresponding to the satisfied learning condition.

A controller of the apparatus determines (a) a quantity of purge gas that passes through the purge control valve, (b) a fuel injection amount correction coefficient for reducing a deviation of an actual air-fuel ratio from a target air-fuel ratio due to the purge gas, (c) a fresh air ratio that represents a ratio of purge air contained in the purge gas to the purge gas, based on the fuel injection amount correction coefficient, and (d) a quantity of the purge air based on the quantity of the purge gas and the fresh air ratio. The controller then controls the internal combustion engine based on the quantity of the purge air.

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。
