Abstract

A fuel injection valve for use in fuel injection systems of compressed-mixture, externally ignited internal combustion engines has a core provided with a wear-resistant layer that has a greater layer thickness than a layer thickness of a wear-resistant layer of an armature facing the core. This greater layer thickness is present at least in an immediate contact area between the core and the armature.
