Bosch 0433271829 Injector Nozzle DLLA150S853

The Bosch 0433271829 (DLLA150S853) is a sac-hole type diesel injector nozzle designed for mechanical pump-line-nozzle injection systems. It features a 150-degree spray angle and is manufactured from high-speed steel (W6Mo5Cr4V2 / 18CrNi8) with vacuum hardening to achieve HRC 62-65 hardness for wear resistance under high-pressure diesel fuel conditions. This nozzle serves as the critical spray-tip component within the complete injector assembly (nozzle holder KBEL109S6/13, assembly 0432292881). It is calibrated for Scania DS 11.15 and DSC 11.01 11-liter diesel engines produced between 1980 and 1990, as fitted to Scania 2-Series and 112/R112 heavy-duty trucks. The nozzle delivers precise fuel atomization for direct-injection combustion chambers. Cross-reference interchange includes Scania OE 313510, Bosch 0433271618, Motorpal DOP150S537-4122, Magneti Marelli DLLA150S853W, and DT Spare Parts 112130. Each nozzle is supplied new in original Bosch packaging. Verification of engine serial number and existing nozzle stamping (DLLA150S853) is recommended prior to installation.
