Bosch original Fuel Injector 0445120161 for ISDE High Pressure Common Rail Diesel Injector, Replacement for OEM 0445120030, Cross Reference 0445120578, 0445120289 for Machinery original new injector

Engineered for accurate fuel delivery in demanding diesel appliions, the Bosch 0445120161 is an original common rail fuel injector for high-pressure fuel systems. Its electronically controlled solenoid and precision needle operation support micron-level injector control, while multi-hole nozzle technology atomizes fuel into a fine mist for efficient combustion. The design supports precise fuel metering, responsive engine operation, improved fuel economy and reduced particulate and NOx emissions, while also helping lower engine noise.
Manufactured to Bosch OEM specifiions, the injector combines high-pressure common rail capability with hardened, wear-resistant components and corrosion-resistant materials for durability and long service life. It is compatible with Cummins ISBe, ISDe, QSB, QSB4.5, QSB6.7 and B Series diesel engines. Equipment coverage includes heavy-duty trucks, buses, excavators, wheel loaders, generator sets, agricultural machinery, mining machinery and road construction equipment, making it suitable for fleet maintenance and varied industrial diesel appliions.
For professional installation, the injector bore should be cleaned, a new sealing washer fitted and all fasteners tightened to the applicable OEM torque specifiion. Electrical connection, fuel-system bleeding, diagnostic scanning and leakage testing complete the procedure. Service life is best supported by high-quality diesel fuel, regular filter replacement, water-contamination prevention, periodic ECU diagnostics and monitoring of injector correction values. The product is supplied in Bosch standard export-grade packaging with a traceable barcode and a 12-month warranty.
