Bosch original Diesel Fuel Injector 0445120132, Replacement for 0445120136, Cross Reference 0445120002, for Construction Machinery, Common Rail Injector 0445120131 original new injector

Built for demanding common rail diesel systems, the BOSCH 0445120132 (0 445 120 132) is an original Bosch 120 Series injector engineered for accurate fuel metering and optimized atomization at operating pressures up to 2200 bar. The ECU calculates injection quantity and activates the electronic control valve, allowing the precision nozzle to deliver atomized fuel into the combustion chamber. Multiple injection events support combustion efficiency, helping improve fuel economy, cold starting and power output while reducing NOx and particulate emissions.
Compatibility covers Cummins ISB 6.7, QSB 6.7 and B Series engines, together with industrial, generator, construction, mining and agricultural diesel engines. Suitable equipment includes commercial and heavy trucks, buses, generator sets, excavators, loaders, mining equipment, agricultural machinery, marine auxiliary engines and industrial power units. Cross references—Cummins 4945381 / 4 945 381, Bosch Reman 0445120133 and alternative 0445120126—support accurate part identifiion for distributors, fleet maintenance teams and equipment service providers.
High-pressure capability, precision injection control, OEM-level durability and long service life support demanding professional use. During installation, clean fuel lines, use new sealing washers, inspect the injector seat, follow OEM torque specifiions, perform coding where applicable and verify fuel pressure. Regular filter replacement, clean diesel fuel, return-flow monitoring and periodic spray-quality inspection help prevent contamination and maintain performance. Hard starting, smoke, power loss, rough idle or high consumption should prompt appropriate injector diagnostics.
