Bosch 0445120377 Common Rail Fuel Injector for Dongfeng Cummins

1. Product Overview

Brand new Bosch 0445120377 common rail fuel injector (type CRIN2-16) for Dongfeng Cummins (DCEC) engines, OE number C5307809 (Cummins 5307809). The OE pairing is confirmed by the manufacturer’s per-model technical file for this number, supported by a Cummins-series catalogue reading (ISL9.5 direction) and several market listings that agree. One caution about sources in this range: in the Cummins-series catalogue, the OE column for the block of numbers around this one is known to drift between neighbouring Bosch numbers, so a value from that column was adopted here only because the per-model file confirms it independently — OE numbers circulating for neighbouring Bosch numbers in this range belong to those numbers and must not be transferred to this injector. No Bosch exchange number has been confirmed, and nozzle / control valve values could not be retrieved in this round, so those fields are left blank.

4. Cross-Reference

Note: no Bosch exchange number, nozzle or control valve could be confirmed for this injector, so none is listed. Order by the Bosch number and the C-prefixed DCEC number engraved on your old unit — do not substitute an OE number taken from a neighbouring Bosch number’s listing.
