摘要： An embodiment (control apparatus) for an internal combustion engine according to the present invention determines, based on an output value Voxs of the downstream air-fuel ratio sensor 67 disposed downstream of a three-way catalyst 43, determines which air-fuel ratio request, a rich request or a lean request, is occurring. The control apparatus sets a target upstream air-fuel ratio abyfr to a target rich air-fuel ratio afRich when the rich request is occurring, and sets the target upstream air-fuel ratio abyfr to a target lean air-fuel ratio afLean when the lean request is occurring. Each of the target rich air-fuel ratio afRich and the target lean air-fuel ratio afLean is varied depending on an intake air amount Ga. Further, the control apparatus increases a purge amount of an evaporated fuel as a magnitude (air-fuel ratio change amount ΔAF, | afLean - afRich | ) of a difference between the target rich air-fuel ratio afRich and the target lean air-fuel ratio afLean becomes larger.

摘要： An air-fuel ratio control apparatus of the present invention includes a determination section and a reverse direction correction introducing section. The determination section determines whether or not an output of the downstream air-fuel ratio sensor falls within a predetermined range whose center corresponds to a target value corresponding to the stoichiometric air-fuel ratio. When the output of the downstream air-fuel ratio sensor falls within the predetermined range, the reverse direction correction introducing section temporarily introduces, to an air-fuel ratio correction in a direction requested by the output, an air-fuel ratio correction in a direction opposite to the requested direction.

摘要： A control apparatus for an internal combustion engine according to an embodiment of the present invention (present apparatus) determines, based on an output value of the downstream air-fuel ratio sensor 67, which a target air-fuel ratio being a target value of an air-fuel ratio of a gas flowing into the catalyst 43 should be set to either a "target rich air-fuel ratio smaller than the stoichiometric air-fuel ratio" or a "target lean air-fuel ratio larger than the stoichiometric air-fuel ratio", and determines a fuel injection amount based on the target air-fuel ratio. The present apparatus comprises an evaporated fuel purge section for introducing an evaporated fuel generated in a fuel tank 51 into an intake passage of the engine. The evaporated fuel purge section starts the evaporated fuel purge when the target air-fuel ratio is set to the target rich air-fuel ratio at a purge execution request condition satisfied time point at which a state has changed from a state in which the purge execution request condition is unsatisfied to a state in which the purge execution request condition is satisfied, and does not start the evaporated fuel purge when the target air-fuel ratio is set to the target lean air-fuel ratio at the purge execution request condition satisfied time point.
摘要翻译：根据本发明的一个实施例（本装置）的用于内燃机的控制装置基于下游空燃比传感器67的输出值来确定目标空燃比作为目标空燃比的目标值流入催化剂43的气体的空燃比应设定为“比理论空燃比小的目标浓空燃比”或大于理论空燃比的“目标稀空燃比” 比率“，并基于目标空燃比确定燃料喷射量。本装置包括蒸发燃料清除部分，用于将在燃料箱51中产生的蒸发燃料引入发动机的进气通道。蒸发燃料清除部分在目标空燃比被设定为目标空燃比时在清除执行请求条件满足时间点开始蒸发燃料清除，在清除执行请求条件满足时间点处状态已经从清除执行状态要求条件不满足净化执行要求条件成立的状态，在净化执行要求条件成立时间内将目标空燃比设定为目标稀空燃比时不开始蒸发燃料净化点。
