ABSTRACT:
A fuel injecting apparatus for an internal combustion engine, comprising a suction manifold and a throttle valve assembly connected to the suction manifold and provided with a fuel injector and a throttle valve. The plane of the opening of each branch pipe of the manifold is formed at a position receded downstream of a joining plane between the suction manifold and the throttle valve assembly to form space between the joining plane and the opening plane, and, at the same time, the branch pipes of the suction manifold are open at predetermined intervals around the central axis of the space which functions as part of a suction passage rotationally in the direction of the operating sequence of the integrated cylinders, whereby suction by each cylinder takes place consecutively in the same rotational direction in the space at the branch pipe inlets, and a swirl is generated at the space formed at the branch pipe inlets, thereby prompting the mixing of the fuel-air mixture and enabling uniform distribution of the mixture to each cylinder.
