Abstract

A holding down plate for fastening a fuel injector in a location orifice of a cylinder head of a mixture-compressing internal combustion engine includes on one end a fastening bore, which is penetrated by a fastening element which fastens the holding down plate to the cylinder head, and the opposite end of the holding down plate has a location orifice for receiving a fuel injector, the location orifice being divided by an insertion recess and delimited by a first and a second fork end, which exert a force on the fuel injector thereby pressing the fuel injector against a pressure shoulder located in the location orifice of the cylinder head. The first and the second fork end are bent in a shape that is undulated in cross-section and is oriented toward the fuel injector, a radius of the undulated bending each forming a support area.
