To provide an internal combustion engine, control device of internal combustion engine, and control method of internal combustion engine for preventing a trouble resulted from the reduction in engine speed according to secondary air supply.
An ECU 50 detects whether secondary air supply is performed or not (S100), and ends a routine processing, when it recognizes that the secondary air supply is not performed, without performing the correction of intake air quantity (S500). When it recognizes that the secondary air supply is performed in S100, the ECU detects whether the vehicle speed is 0 or not (S200). When the vehicle speed is 0, the routine processing is ended after performing the processing of intake air quantity correction A (S300). When the vehicle speed is not 0, the routine processing is ended after performing the processing of intake air quantity correction B (S400).
