摘要：A control device of an internal combustion engine includes a target air-fuel ratioset portion that sets a target air-fuel ratio according to an operating state of the internalcombustion engine, an air-fuel ratio detection portion that detects an actual air-fuel ratio,

a feedback correction value calculation portion that calculates a feedback correctionvalue to correct a fuel injection amount for the actual air-fuel ratio to coincide with thetarget air-fuel ratio, and a fuel property change determination portion that determines achange of a fuel property on the basis of a change of a correction amount including acorrection value for the fuel injection amount calculated on the basis of the feedbackcorrection value in addition to the feedback correction value. The control device candetermine a change of the fuel property accurately even when a change of the feedbackcorrection value is reflected on another correction value.
