するスロツトル弁開度調整装置。 In an internal combustion engine in which an injector is disposed upstream of a throttle valve and the throttle valve is driven by an electric motor, an accelerator sensor detects the opening degree of the accelerator pedal, a water temperature sensor detects the engine cooling water temperature, and an engine rotation an engine rotation speed sensor that detects the maximum throttle valve opening according to the engine rotation speed and the cooling water temperature; If the accelerator pedal opening is larger than the maximum throttle valve opening determined by the cooling water temperature, the electric motor is driven so that the maximum throttle valve opening becomes the throttle valve opening, and the throttle valve opening is set to the maximum throttle valve opening. and control means for driving the electric motor so that when the opening of the accelerator pedal is smaller than the opening of the accelerator pedal, the throttle valve opening corresponds to the opening of the accelerator pedal. Adjustment device.
