Common-rail injector, Bosch 0445120212 (also written 0 445 120 212), control valve F00RJ02697. It is a CRI2 second-generation common-rail unit for Cummins ISB3.9, ISB5.9, ISBe, 6ISBE and QSB3.9 engines, fitted in CAT C6.5 excavators, Case heavy equipment, Ford Cargo trucks and DAF, IVECO and Volkswagen commercial vehicles.

Physical data: 21.5 x 4 x 4 cm, 344 cm3, 0.6 kg per piece. VCO-type nozzle with 7 holes (varies slightly with calibration), flow around 720 cc/min, working pressure up to 1600 bar with injection timing and quantity controlled independently by the ECU, supporting multiple injection events.

The injector code (C2I) must be written into the ECU after fitting. Without it the engine runs rough at idle, smokes white, burns more fuel, and may set a DPF fault.

The most common and most expensive mistake with this part number is fitting a new injector onto a contaminated fuel system. If the CP3 high-pressure pump has shed metal — the diesel looks bright or glittery — the rail must be flushed and the pump replaced at the same time. A new injector on a contaminated rail fails again within hours, and that failure is then argued about as a warranty case.
