Abstract
An attachment of a fuel injection valve is formed at least from the main body and the insert which bound the gas supply passages between them and direct the gas in a metered and targeted manner onto the sprayed fuel. The attachment makes it possible to separate the functions of gas supply and metering from those of sealing the fuel injection valve against an induction conduit and fastening the attachment on the fuel injection valve. Furthermore, the design configuration results in a large number of variants which can be achieved by very simple and low-cost exchangeability of parts by virtue of the modularity of the system. The fuel injection valve is particularly suitable for fuel injection systems of mixture compressing internal combustion engines with external ignition supply.
