Delphi L123PBB Injector Nozzle Assembly

The Delphi L123PBB is a common rail diesel injector nozzle designed for high-pressure direct injection systems. It corresponds to the Bosch DLLA147P1048 nozzle geometry featuring a 147-degree spray angle. The component is manufactured from hardened tool steel to withstand combustion pressures exceeding 1800 bar and ensure wear resistance over extended service intervals. This nozzle serves as a critical component within the fuel injector assembly, responsible for fuel atomization and spray pattern formation. It is referenced by Mercedes-Benz OE part numbers A0260746602 and 0260746602 for OM904 and OM906 engine applications. Cross-references include Bosch 0 433 171 679 and Lucas LDFN0169. Dimensional inspection and flow testing are required prior to installation to maintain injection calibration.
