Kind Code:
A1
Abstract:
[Problem] To provide a fuel injection device suitable for miniaturizing an internal combustion engine, and also suitable for supplying fuel to a combustion chamber. [Solution] The present invention relates to a fuel injection device 10 provided with: a main body part 20 which forms a passage portion 24 serving as a portion of an intake passage of an internal combustion engine; and an injector 22 disposed in the main body part. The main body part 20 is provided with a first wall part 40 extending out from the passage portion 24. The first wall part 40 is shaped to support the injector so that the tip part of the injector faces the outside of an outlet opening 24b of the passage portion. The main body part 20 is formed such that, in a second direction different from a first direction in which the first wall part extends out from the passage portion, a first passage portion 46 partially formed by the first wall part has an expanded cross-sectional shape compared to the cross-sectional shape of the inlet opening 24a of the passage portion.
