Bosch 0445120227 Common Rail Fuel Injector

1. Product Overview

Brand new Bosch 0445120227 common rail fuel injector (type CRIN2-16, 1600 bar), supplied by Wuhan Ranyingyi Trading Co., Ltd. (injector-factory.com). Its nozzle 0433172182 (DLLA151P2182) and control valve F00RJ01692 are confirmed by multiple sources, and the nozzle is shared with 0445120228. The application, however, is NOT settled: market listings call this a Weichai WP12 injector, but the only technical-file OE number on record sits in the 612600080xxx range — the same range as the WD10 / WP10 injector 0445120224 — which does not match the 612630090xxx range normally used for WP12. Because the two lines of evidence contradict each other, no OE number and no engine application are stated as fact here, and this page deliberately does not force the number into a WP12 fitment. Neighbour warning: 0445120224 is in the same OE number range with a different OE tail number — the two must never be mixed. 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 — market “Weichai WP12” claims conflict with the OE number range on record; 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 OE candidate 612600080977 (Weichai) rests on a single technical file with no second source anywhere, and its number range conflicts with the market’s WP12 claim — it is NOT a confirmed OE number for this injector. No Bosch exchange number could be confirmed.
