Bosch 0445120291 Common Rail Fuel Injector

1. Product Overview

Brand new Bosch 0445120291 common rail fuel injector, supplied by Wuhan Ranyingyi Trading Co., Ltd. (injector-factory.com). Bosch parts data records nozzle 0433172123 (= DLLA150P2123) and control valve F00RJ02806 for this number, both with a second source. No Yuchai OE number could be found for this injector, so none is stated. The application (Yuchai YC6J, EU4) rests on a single market source with a catalogue fragment pointing the same way — not enough to state as fact — and the exchange candidate likewise rests on a single market listing. This injector shares its control valve with 0445120290 but uses a different nozzle — the two are NOT interchangeable. It is not related to 0445110291, a passenger-car CRI-series injector that merely shares the tail number. Always order by the number engraved on your old injector, and send us a photo of the engraving before ordering so we can verify the match free of charge.

3. Fitment

To be confirmed — single-source market evidence suggests Yuchai YC6J (EU4), but this is not confirmed; contact us with the engraved number or VIN. Fitment data is for reference only — please confirm by the number engraved on your old injector or send us your VIN before ordering.

4. Cross-Reference

Note: the exchange candidate 0986AD1088 rests on a single market listing — unconfirmed, and NOT stated as this injector’s exchange number. A repair-kit listing also names 0445120165 alongside this number: the two share only the repair kit / valve, not an OE number or application. Not related to 0445110291 (passenger-car CRI series).
