機関の混合気供給装置。 A fuel injection valve is disposed in an intake passage upstream of the intake throttle valve, and an air flow rate measuring means is provided in an intake distribution passage whose downstream end is opened in the intake passage upstream of the intake throttle valve. In an internal combustion engine configured to variably control the idle speed of the engine by adjusting the opening degree of an idle speed control valve installed in a bypass passage connecting upstream and downstream of a throttle valve, the upstream end of the bypass passage is An air-fuel mixture supply device for an internal combustion engine, characterized in that a measuring branch passage is opened in an intake passage upstream of the fuel injection valve and extends from near a downstream end of the intake branch passage to the bypass passage.
