PURPOSE:To ensure a prescribed feed quantity of fuel at a high load and the like, by injecting the fuel from a main fuel injection valve and starting fuel injection valve when a flow of fuel injection after starting exceeds a maximum flow of fuel injection of the main fuel injection valve. CONSTITUTION:A pump 42 feeds fuel from a fuel tank 43 to a main fuel injection valve 41 througi a fuel passage 44. A starting fuel injection valve 46, injecting excess fuel at a cold temperature start, is provided to a surge tank 4 and connected to the fuel passage 44. An electronic control unit 40 controls the main fuel injection valve 41, starting fuel injection valve 46, bypass flow control valve 22, exhaust gas recirculation (EGR) control valve 24, ignition coil 45, etc. When a flow of fuel injection after starting exceeds a maximum flow of fuel injection of the main fuel injection valve 41, fuel is injected from the both fuel injection valves 41, 46. |
