Abstract

A fuel injection valve having a nozzle body can be inserted into a receiving bore of a cylinder head of an internal combustion engine for direct injection of fuel into the combustion chamber of the internal combustion engine. A metal ring arranged on the nozzle body is deformed when heated, producing a radial pressure of the fuel injection valve in the receiving bore only when heated after the fuel injection valve has been inserted into the receiving bore.
