Designed for high-pressure common rail diesel systems, the BOSCH 0445120122 is an original new electronic solenoid injector engineered for precise fuel metering and optimized atomization. Its common rail direct injection technology supports accurate injection timing, efficient combustion and consistent fuel delivery under demanding operating conditions. By helping improve fuel economy, cold-start performance and engine power output while reducing black smoke and NOx emissions, it provides OEM-level performance for heavy-duty diesel appliions.
The injector is compatible with Cummins ISBe4.5, ISBe6.7, ISDe4.5, ISDe6.7, QSB4.5 and QSB6.7 engines, as well as Cummins B Series common rail engines. Typical installations include Dongfeng and Foton trucks, Yutong, King Long and Golden Dragon buses and coaches, Sinotruk vehicles, and XCMG, LiuGong and SANY equipment. It also serves agricultural diesel engines, industrial power units and construction equipment. Cross references include Cummins 3965721, 3976372, 4937065, 4940640, 3977080, 4988835, 4937512, 5258744 and 5258744RX.
For distributors, fleet maintenance programs and repair operations, the injector offers a practical replacement solution backed by Bosch manufacturing standards and a 12-month warranty. Correct installation includes cleaning the injector seat, replacing the sealing washer, inspecting the fuel return line and conducting a leak-off test; ECU coding should be performed when required. Always verify the injector calibration code and engine serial number before purchase to confirm the correct appliion.
