Bosch original Common Rail Diesel Fuel Injector 0445120097, 5263310, 0445120237, 0445120101, High Pressure Diesel Auto Parts for Fuel System Applications original new injector

Built for demanding heavy-duty diesel appliions, the Bosch 0445120097 common rail fuel injector combines electronically controlled operation with Bosch CRIN technology. It is designed to deliver precise fuel metering and optimized atomization, supporting efficient combustion, reduced fuel consumption, increased power output, lower emissions, and extended engine service life. Fuel is pressurized by the high-pressure pump and stored in the common rail accumulator before ECU signals activate the injector solenoid for controlled injection.

This injector is identified by Bosch standard number 0 445 120 097 and exchange number 0986435555. Its reference network also includes OEM numbers 4934411, 4944476, 5263310, 84347519, and 87708024, plus compatible injector numbers 0445120144 and 0445120237. The specified DLLA128P1739 nozzle and F00VC99002 control valve support needle regulation and fuel atomization. Appliions cover Cummins ISC, ISC8.3, ISL, ISL8.9, QSL, and QSL8.9 engines, as well as CASE, CASE IH, and New Holland equipment, generator sets, mining machinery, and heavy-duty industrial equipment.

For installation, the injector seat should be cleaned thoroughly, the copper washer and O-rings replaced, and the fuel rail and lines inspected. After fitting the injector, torque it according to OEM specifiions, connect the electrical connector, perform injector coding if required, and conduct a leak-off test. Final checks include starting the engine, checking rail pressure and return fuel flow, and verifying ECU fault codes, helping technicians confirm correct fuel-system operation.
