摘要： PROBLEM TO BE SOLVED: To provide a fuel injection amount control device of an internal combustion engine, capable of avoiding the increase of an NOdischarge amount as much as possible when the nonuniformity of air/fuel ratios among cylinders occurs.SOLUTION: The control device performs main feedback control such that the air/fuel ratio represented by an output value of an upstream side air/fuel ratio sensor is conformed to the target air/fuel ratio. Further, the control device gains an air/fuel ratio imbalance index value which becomes larger as the differences among the cylinders of the air/fuel ratio of a mixed gas supplied to respective combustion chambers is large, and the target air/fuel ratio is corrected to the rich side as the gained air/fuel ratio imbalance index value is large. Then, the control device separately calculates a stoichiometric correction term (first correction amount) for conforming a real average air/fuel ratio to the reference air/fuel ratio in the range of the window of catalysts and an enriching correction term (second correction amount) for conforming the real average air/fuel ratio to an air/fuel ratio of the reference air/fuel ratio or less, based on the air/fuel ratio imbalance index value, and determines the target air/fuel ratio by using them.
摘要翻译：要解决的问题：为了提供一种内燃机的燃料喷射量控制装置，能够尽可能地避免NO X 放电量的增加气缸之间的空气/燃料比的不均匀性发生。解决方案：控制装置执行主反馈控制，使得由上游侧空气/燃料比传感器的输出值表示的空气/燃料比符合目标空燃比。此外，控制装置获得随着供给到各个燃烧室的混合气体的空气/燃料比的气缸之间的差异大而变大的空气/燃料比不平衡指数值，并且校正目标空气/燃料比由于获得的空/燃比失衡指数值较大，因此向富裕方向发展。然后，控制装置分别计算在催化剂窗口的范围内的实际平均空燃比与参考空燃比一致的化学计量校正项（第一校正量）和丰富校正项（第二校正量）基于空/燃比不平衡指数值，将实际平均空燃比与基准空燃比的空燃比一致，并通过使用它们来确定目标空燃比。版权所有（C）2012，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a technology for accurately determining abnormality in a PM discharge amount in an abnormality determination device for an internal combustion engine. SOLUTION: An abnormality determination device for an internal combustion engine includes: a first determination method estimating a PM deposition amount collected by a DPF based on an operating state of the internal combustion engine to determine that forced regeneration of a filter should be performed at the time when the estimated PM deposition amount reaches a predetermined amount; and a second determination method determining that the forced regeneration of the filter should be performed at the time when front-to-back pressure difference of the DPF reaches a predetermined pressure, and when the first determination method or the second determination method determines that it is the time when the forced regeneration of the filter should be performed, in the case where the estimated PM deposition amount used in the first determination method is less than the predetermined amount, the PM discharge amount is determined to be abnormal.
