Bosch original Common Rail Diesel Injector Series Fuel Injector 0445120366, 0445120368, 0445120029, 0445120369 for Excavator, Replacement for OEM Compatible original new injector

Built around Bosch’s CRIN3-18 injector platform, the 0445120366 is an electronically controlled common rail diesel injector for high-pressure fuel delivery in heavy-duty diesel appliions. It is suitable for Cummins QSB6.7, ISB6.7 and B6.7 engines and supports construction, agricultural, industrial, mining and commercial vehicle equipment. Bosch OE number 0 445 120 366 cross-references to Bosch Exchange 0986435573 and Cummins numbers 5271684 and 4983514, helping distributors and service buyers identify the required replacement accurately.

Within the common rail system, the injector receives an ECU command and uses the F00RJ02410 control valve to regulate needle movement. Fuel is then discharged through the DLLA145P2144 nozzle, producing fine atomization for more complete combustion. Precision fuel metering, optimized injection timing and spray pattern support power output, fuel economy and reduced particulate emissions. The injector is engineered for operating pressures exceeding 1800–2000 bar, while premium alloy steel construction and Bosch manufacturing tolerances contribute to durability and consistent performance.

Manufactured according to Bosch OE standards, this injector offers an OEM-oriented solution for engine maintenance, fleet support and industrial power systems. Its appliion coverage includes generator sets, compressors, excavators, wheel loaders, tractors, harvesters and medium- or heavy-duty trucks. For correct installation, the injector washer, O-ring seals, leak-off seals and fuel return seals should always be replaced. These attributes make it a practical choice for professional diesel injection servicing.
