For fuel injection control in a cylinder direct-injection engine, fuel injection beginnings for injecting fuel successively into a plurality of cylinders are calculated; threshold voltage impression beginnings at which a threshold voltage for starting to inject the fuel from injectors is applied are calculated, corresponding to the fuel injection beginnings, and the ends of the threshold voltage impression are calculated; it is determined whether or not a first period between the beginning and end of threshold voltage impression for a preceding cylinder is coincident with a second period between the beginning and end of threshold voltage impression for a succeeding cylinder; and the second period is modified so as to be earlier or later than the first period, if the two periods are coincident with each other.
