Abstract

A fuel injection valve has an attachment with a two-part design including a main body and an insert. With the attachment, the functions of supplying and metering gas are optimized independently of the functions of sealing off the fuel injection valve with respect to an intake conduit and of securing the attachment onto the fuel injection valve. In addition, the fuel injection valve and attachment provide a modular system which allows a large number of possible variations which can be achieved by simple and inexpensive component changes.
