ABSTRACT:
A fuel control device for an internal combustion engine determines that the internal combustion engine is in a transient state, by a criterion D, and makes fuel correction, where the transient-state criterion D is set to be a more relaxed criterion (=|ΔTHaf|) when forcible modulation control is being performed, compared with a normal criterion (=|ΔTHn|) used when the forcible modulation control is not being performed.
