摘要

The fuel injector (10) comprises a mounting body (12) and a nozzle body (22) and other fluid impinging components, which forms a screw connection for connecting a nozzle tensioning bolt (26). A surface exposure is performed at a surface side (28) of the mounting body. The surface exposure is performed in a depth of preferring 0.02 millimeters at the front surface of the mounting body.
