PURPOSE:To completely prevent respectively a misfire from being generated and an NOX generating amount from increasing even when not realized-a desired recirculation rate due to an adjusting delay by actuating together two kinds of fuel injection valves when detected the adjusting delay of recirculated exhaust gas amount. CONSTITUTION:An internal combustion engine is provided with the first fuel injection valve 7 for attaining stratified combustion by directly injecting fuel into a combustion chamber 1 and the second fuel injection valve 10 for attaining uniform combustion by injecting fuel to an intake passage 3 in the downstream of a throttle valve 9. On the other hand, the intake passage 3 in the downstream of the throttle valve 9 communicates with an exhaust passage 5 in an exhaust gas recirculating passage 11, to arrange therein a control valve 12 for controlling a recirculating exhaust gas amount. Here in a control device 20, based on each detection signal from each sensor 21 to 23 for detecting an operating condition of the internal combustion engine, both the fuel injection valves 7, 10 are switched to be actuated. When an adjusting delay of the recirculating exhaust gas amount is detected at switching time, both the fuel injection valves 7, 10 are actuated together. |
