Bosch 0445120292 Common Rail Fuel Injector for Yuchai YC4E YC6J

1. Product Overview

Brand new Bosch 0445120292 common rail fuel injector for Yuchai YC4E / YC6J (EU4) engines, fitted to Yutong and Kinglong buses. The OE number J6A00-1112100-A38 and the exchange number 0986AD1037 each rest on a single technical-file source and are marked accordingly — confirm them against the engraving on your old injector. This injector belongs to the same nozzle / valve / exchange family as 0445120110 (whose OE is J5600-1112100-A38): the two pages are cross-linked, and the two injectors can only be told apart by the engraved numbers. Warning on the consecutive Yuchai numbers: 0292, 0293 and 0294 carry different OE prefixes (J6A00 / A6A00 / K6000) and different nozzles — never carry one number’s data across to another.
