Bosch original Common Rail Injector Assy 0445120120, Diesel Fuel Injector 0986435543, Replacement for OEM, Cross Reference 4945807, for Vw, ford Cargo, VW/Volkswagen original new injector

Built for accurate fuel delivery in modern high-pressure diesel systems, the BOSCH 0445120120 (0 445 120 120) is an electronically controlled common rail injector for commercial vehicles, industrial engines and construction equipment. High-pressure fuel is supplied from the common rail, while the ECU determines injection timing and fuel quantity through the solenoid valve. Controlled needle lift and precision nozzle atomization support efficient combustion, consistent engine performance and optimized fuel delivery.

Precision nozzle technology, high-pressure operation and high-strength alloy steel construction provide stable atomization, accurate fuel metering, corrosion resistance and industrial-grade durability. Multiple injection capability supports lower NOx emissions, reduced particulate matter and lower engine noise, while contributing to improved fuel economy, enhanced engine power and better cold-start performance. Bosch OEM quality and a 12-month warranty make the injector suitable for demanding replacement and maintenance programs. Emission compatibility includes Euro III, Euro IV and Euro V.

Engine coverage includes Cummins ISBe, ISDe and QSB 4.5/6.7 models, plus EQB, B Series and C Series platforms. Appliions extend to Dongfeng, Foton, JAC, FAW and Sinotruk trucks, King Long and Yutong buses, SANY, XCMG and LiuGong equipment, generator sets and agricultural machinery. During installation, clean the injector bore, replace the copper sealing washer, verify rail pressure and complete injector coding where required. Confirm cross-reference numbers against the engine serial number and coding requirements before ordering.
