PURPOSE: To improve the fuel consumption decreasing effect by providing a control means for releasing a clutch during supply of fuel in a state where the throttle opening is substantially full closed, and controlling the engine so that the engine may perform the idle operation. CONSTITUTION: An intake pipe full close means 16 is composed of a full close valve 36 arranged on an intake passage 8 upstream from a throttle valve 10, a bypass passage 38 for bypassing the full close valve 36 and the throttle valve 10, and a solenoid 40 to be controlled by a control means 14 for opening and closing the full closing valve 36. At this time, the throttle valve 10 is so provided as to be opened and closed by being interlocked with the depressing operation of an accelerator pedal 42. When the operating state is the idle operating state, the solenoid 40 is turned on, the full close valve 36 is closed, and the intake air flow rate is made into the full close state. Moreover, when the operating state is normal, the solenoid 40 is turned off, the full close valve 36 is released, and the intake air flow rate is adjusted by the throttle opening. |
