項記載の内燃機関の燃料噴射装置。[Scope of Claim for Utility Model Registration] 1. A large hole opening facing the intake passage of a fuel injection valve in which a small diameter portion, a medium diameter portion, and a large diameter portion are arranged sequentially from the tip of the fuel injection valve, and a small hole within the large hole. Insert into 1. In the fuel injection device for an internal combustion engine that injects fuel into the intake passage, the large-diameter portion and/or the medium-diameter portion of the fuel injector are attached to the outer surface of the large hole via a seal ring, and the tip of the medium-diameter portion is attached to the outer surface of the large hole through a seal ring. Fitted into the large hole with a gap, forming an annular groove on the outer periphery of the small diameter portion,
A fuel injection device for an internal combustion engine, characterized in that a sealing member is fitted within the bay, and the intake passage is fluid-tightly fitted into the small hole of the intake passage via the sealing member. 2. The fuel injection valve is of a type that does not have a needle portion at the tip of the injection nozzle.Claim 1 of Utility Model Registration
A fuel injection device for an internal combustion engine according to paragraph 1.
