| titleOfInvention | Control systems for internal combustion engines |
| abstract | The internal combustion engine includes an exhaust purification catalyst (20). The control system includes temperature detection means (46) for detecting or estimating the temperature of the exhaust purification catalyst, executes feedback control so that the air-fuel ratio of the exhaust gas flowing into the exhaust purification catalyst becomes the target air-fuel ratio, and executes the A target air-fuel ratio setting control in which the target air-fuel ratio is alternately set as a rich set air-fuel ratio and a lean set air-fuel ratio. In addition, when the temperature of the exhaust purification catalyst detected or estimated by the temperature detection means is below a predetermined upper limit temperature, the control system increases the pass A fluctuation difference obtained by subtracting the rich degree of the rich set air-fuel ratio from the lean degree of the lean set air-fuel ratio. As a result, the storage amount of the sulfur component of the exhaust purification catalyst is kept low. |
