    摘要： A motor-driven throttle valve control device has a throttle shaft and a coupling lever rotatably provided on the shaft, both being coupled by a spring. A default spring energizes the coupling lever toward a position of the default opening of the throttle valve. The throttle shaft rotates separately from the coupling lever in the direction of the full open throttle valve from a point at which the coupling lever comes into contact with a stopper defining the default position and, together with the coupling lever, in the full close direction of the throttle valve from the point. Thereby, the throttle valve can be kept at the default position by the default spring through the coupling lever when a motor driving the throttle valve is not powered.

    摘要： A control device for an internal combustion engine is configured to switch over at least one of fuel injection amount and ignition timing to an emergency traveling mode in the event that an electric actuator for driving a throttle valve malfunctions, at which time the throttle valve is set at a default position. At the time of the emergency traveling mode, throttle valve opening degree is set at a value larger than the opening degree when an accelerator pedal is not depressed during normal operation. Fuel amount is set to obtain necessary engine rpm for the emergency traveling mode and when the acceleration pedal is not depressed or the vehicle speed is zero, ignition timing is retarded with respect to ignition timing during normal idling operation.
