PURPOSE:To expedite the response speed in the detection of the air intake pressure, at the time of engine transition, by reducing the function of a smoothing function which smoothes the output of a pressure sensor. CONSTITUTION:The air, which is taken through an air cleaner 2, is supplied to the engine 1 through an intake pipe 3 and exhausted through an exhaust pipe 5. The output of the pressure sensor 8 which is provided at the down stream of a throttle valve 4 is supplied to a control circuit 7 of a fuel injection valve 6 through an intake pressure detecting circuit 9. A transition state sensor 10 detects the fact that the variation in the opening degree of the throttle valve 4 becomes large, reduces the smoothing function of the circuit 9, thereby expediting the response speed of the valve 6. |
