Abstract

Fuel rails which need an injector usually have an injector clip with a Cr(VI)-free coating layer. Unfortunately friction between the contact surfaces may damage the layer during the assembly of the electro-injector (EI) and the fuel rail. In fact in the current process at first the clip is assembled on the injector (Fig. 1, left), then the clip and the injector group is fixed on the fuel rail injector cup (Fig. 1, right). During this process the coating may be damaged, which compromises the corrosion resistance of the parts.
