Abstract: A method for controlling fuel injection of a GDI(Gasoline Direct Injection) engine using a piezo injector is provided to raise volumetric efficiency by increasing density of intake air and to prevent knocking phenomenon from occurring at an engine due to cooling effect. A method for controlling fuel injection of a GDI engine using a piezo injector comprises steps of performing primary fuel injection by calculating primary target injection time in consideration of driving conditions and then calculating target amount of air and target injection time, and performing secondary fuel injection by determining if an engine operation mode is ultra lean burn mode or constant driving mode. It is determined if the target injection time is smaller than minimum reference injection time and the engine operation mode is the ultra lean burn mode. If the target injection time is smaller than minimum reference injection time and the engine operation mode is the ultra lean burn mode, the target injection time is corrected.
