PURPOSE: A method for controlling direct fuel injection is provided to prevent the degradation of resolution of a timer by freely synchronizing a reference point to the operation reference timing and end timing of the timer according to the count of a crank angle sensor. CONSTITUTION: A method for controlling direct fuel injection includes the steps of: calculating the end angle of an injector according to an engine rpm and an intake amount; changing the end angle of the injector into a time; calculating the time for a fuel injection amount; calculating injector start timing by subtracting fuel injection time from injector end time.
