In a V-type engine provided with a variable valve timing mechanism and variable valve lift mechanism for an intake valve, a torque difference between respective banks is obtained. In a region in which an opening area of the intake valve is larger than a threshold, valve timing of the intake valve by the variable valve timing mechanism is corrected so as to reduce the torque difference, whereas in a region in which the opening area of the intake valve is smaller than the threshold, lift characteristics of the intake valve by the variable valve lift mechanism is corrected so as to reduce the torque difference.
