An engine (1) includes first nozzles (Di1 to Di4), second nozzles (Pi1 to Pi4) and a control unit (2). The first nozzles (Di1 to Di4) are arranged in cylinders (#1 to #4), and inject fuel directly into the cylinders (A1 to A4) respectively. The second nozzles (Pi1 to Pi4) are arranged in intake ports (B1 to B4) of the cylinders (#1 to #4), and inject fuel into the intake ports respectively. The control unit (2) controls fuel injection of the first nozzles (Di1 to Di4) and the second nozzles (Pi1 to Pi4). When the engine (1) is started, the control unit (2) performs initial fuel injection by one of the first and second nozzles into the cylinders having odd-number of initial ignition order, and performs initial fuel injection by the other one of the first and second nozzles into the cylinders having even-number of initial ignition order.
