| titleOfInvention | Control device for internal combustion engine |
| abstract | PROBLEM TO BE SOLVED: To provide a control device of an internal combustion engine capable of suppressing a decrease in accuracy of detection of an air-fuel ratio by an air-fuel ratio sensor arranged in an exhaust passage of the internal combustion engine. A control device for an internal combustion engine is arranged in an exhaust passage of the internal combustion engine, and air-fuel ratio sensors 40, 41 for detecting an air-fuel ratio of exhaust gas, and a current detection device 61 for detecting an output current of the air-fuel ratio sensor. A voltage applying device 60 for applying a voltage to the air-fuel ratio sensor, and a voltage control unit 81 for controlling the voltage applied to the air-fuel ratio sensor via the voltage applying device. The voltage control unit sets the applied voltage to a reference voltage that is set so that the output current becomes zero when the air-fuel ratio of the inflowing exhaust gas flowing into the air-fuel ratio sensor is the stoichiometric air-fuel ratio, and the inflowing exhaust gas exhaust The reference voltage is corrected so that the output current detected by the current detection device becomes zero when the fuel ratio is determined to be the stoichiometric air-fuel ratio.
