化器。A fuel injection valve disposed on the upstream side of a throttle valve facing the throttle valve, and an idle bypass passage whose inlet and outlet are opened to throttle bores at positions upstream and downstream of the throttle valve, bypassing the throttle valve. In the fuel injection carburetor for an internal combustion engine, the fuel spray angle range of the fuel injector is defined as the full throttle opening of the throttle valve, in which the position where the sprayed fuel reaches the throttle valve surface changes from a fully closed state to a fully open state. The fuel injector is always located closer to the downstream opening tip than the upstream opening tip of the throttle valve, and the outlet of the bypass passage is located within the throttle bore of the throttle valve. A fuel injection carburetor for an internal combustion engine that is arranged on the inner wall on the tip side of the upstream flow direction.
