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.
