FUEL INJECTION NOZZLE AND METHOD FOR INCREASING THE RESISTANCE OF A NOZZLE OF THIS TYPE FROM AN OPERATION-RELATED DETERIORATION OF INJECTION PROPERTIES

摘要

The invention relates to a fuel injection nozzle (1) with a nozzle body (2), which has a fuel supply duct (5, 17, 19), and with an injection hole (13), which extends through the nozzle body (2) to the fuel supply duct (5, 17, 19). The wall of the injection hole (13) is provided with a coating that is resistant to deposits.
