The present invention relates to a fuel injection control apparatus for controlling fuel injection and a method therefor in an engine having first and second intake passages provided with first and second fuel injection valves, respectively. Fuel injection modes using the two injection valves include an alternative injection mode in which the first and second fuel injection valves are alternately operated every predetermined number of cycles and a combined injection mode in which both the first and second fuel injection valves are used for each cycle. Then, the combined injection mode is selected in a full load range. In a partial load range, the alternative injection mode is selected in a cold state and the combined injection mode is selected after warm-up. Accordingly, it is possible to reduce an equilibrium amount of adhering fuel to an inner wall of an intake passage.
