In this case, when the variation of intake air pressure is little, the annealing value of intake air pressure is made to be great while being extended beyond the range of the variation of actual load, its transition time air-fuel ratio correction factor being changed corresponding so that regulating time for fuel is thereby extended. On the other hand, when the variation of intake air pressure is great, the annealing value is made to be little so as to be approximated to change in actual pressure so that the follow-up performance of the quantity of fuel injection can thereby be enhanced. Thus, the emission of exhaust gas and drivability at the transition time can positively be improved.
