Bosch original Common Rail Diesel Fuel Injector 0445120185, Cross Reference 4940095, 044512055, 3999834, 6.7L Truck Engine Parts, Fits for Pickup 4X4 Dodge Ram original new injector

Built for high-pressure common rail systems, the BOSCH 0445120185 (0 445 120 185) is a brand-new, original electronic solenoid diesel injector engineered to Bosch OE specifiions. Within the system, the ECU determines the required fuel quantity and activates the solenoid, allowing precise needle lift and fuel atomization through the nozzle. This controlled process supports accurate fuel metering, multiple injection events, efficient combustion, improved power output and fuel economy, while helping reduce exhaust emissions and engine noise.

The injector is intended for Cummins ISBe4.5, ISBe6.7, ISDe4.5, ISDe6.7, QSB4.5 and QSB6.7 engines, as well as listed Cummins industrial diesel engines and generator power units. Its appliion coverage includes heavy- and medium-duty trucks, commercial vehicles, buses, construction machinery, excavators, wheel loaders, road equipment, agricultural equipment and diesel generator sets. Cross references include Bosch 0986435508 and Cummins 4892795, 3976372 and 5258744, supporting part-number verifiion for replacement sourcing.

Designed for demanding conditions, the injector provides stable injection pressure, durability and consistent performance under heavy loads. Installation requires part-number and engine-compatibility checks, clean mounting surfaces and new sealing components. Follow OEM torque specifiions, perform injector coding when required, and conduct leak and pressure testing. Preventive maintenance includes high-quality diesel fuel, regular fuel-filter replacement, contamination avoidance and monitoring of injection correction values. These measures support reliable operation across commercial vehicle, industrial and power-generation appliions.
