Bosch 0445120372 Common Rail Fuel Injector for Yuchai

1. Product Overview

Brand new Bosch 0445120372 common rail fuel injector (type CRIN2-16) for Yuchai (Yuchai Machinery) engines. The manufacturer’s technical file for this number gives OE number S5000-1112100-A38 and compatible Bosch number 0445120426; the OE pairing rests on that single source and is marked accordingly, while a general catalogue reading for this number range corroborates the Yuchai brand direction. Yuchai’s …-1112100-A38 OE format is shared across a family of different Bosch numbers, each with its own prefix — J6A00-… belongs to 0445120292 and A6A00-… to 0445120293 — and the prefixes are NOT interchangeable, so check every character against your old injector. No Bosch exchange number, nozzle or control valve has been confirmed, so those fields are left blank. The neighbouring number 0445120373 is a Weichai injector — a different maker entirely; do not confuse the two.

3. Fitment

Yuchai (Yuchai Machinery) engines (specific engine model to be confirmed against your old injector’s engraving — the OE pairing rests on a single technical-file source). 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: no Bosch exchange number, nozzle or control valve could be confirmed for this injector, so none is listed. Within the Yuchai -A38 family the prefix decides the injector — S5000- is this number only.
