Engineered for precise diesel fuel delivery, the Bosch 0445120241 is a new, factory-calibrated, OEM-standard common rail injector within the Bosch 120 Series. Its electronic solenoid control supports accurate fuel quantity metering and optimized spray formation for Common Rail Direct Injection systems. Designed for demanding operating conditions, it is intended to support combustion efficiency, power output, fuel economy and reduced particulate emissions while maintaining long-term durability.
The 0445120241, also formatted 0 445 120 241, cross-references Bosch 0445120070, 0986AD1954, 0986435508 and F00RJ02418, together with Cummins 5263304, 3976631, 4930485 and additional listed Cummins and aftermarket numbers. Engine coverage includes Cummins QSL9, ISLe, ISC, ISCe and QSC, as well as industrial, marine and generator QSL variants. Equipment appliions span heavy-duty trucks, commercial vehicles, intercity buses, construction and agricultural machinery, industrial power generation, marine auxiliary engines, mining equipment and oil and gas field equipment.
During operation, the ECM evaluates engine load, RPM, fuel demand and emission requirements before signalling the injector solenoid. The needle valve then opens, allowing atomized fuel from the common rail accumulator to enter the combustion chamber; the documented high-pressure pump range is 300–1800 bar. For installation, verify the injector number and engine serial number, clean the injector bore and fuel rail system, replace the copper washer and replace O-rings where applicable.
