射気化器。(1) A fuel injection valve disposed on the upstream side of a throttle valve installed in an intake passage of a throttle body and facing the throttle valve, and the intake passage at positions upstream and downstream of the throttle valve, bypassing the throttle valve. In a fuel injection carburetor for an internal combustion engine having an idling bypass passage whose inlet and outlet are opened at In the range of the full throttle opening of the throttle valve from the state to the fully open state,
The fuel injection valve is arranged so that it is always closer to the downstream opening tip than the upstream opening tip of the throttle valve, and is placed in the middle of the idle bypass air passage, so that when the temperature is high, the fuel injection valve a wax type bypass air valve that reduces a flow area of the valve; and a hot water passage that circulates engine cooling water from a position near the downstream opening tip of the throttle valve in the throttle body through the wax portion of the wax type bypass air valve. A fuel injection carburetor for an internal combustion engine, comprising:
