Bosch original Common Rail Diesel Fuel Injector 0445120211, for heavy duty diesel engine application, 0445120210, 0445120216, 0445120327 – Excavator Engine Injector Replacement original new injector

Built for high-pressure common rail systems, the BOSCH 0445120211 (0 445 120 211) is a genuine new, electronically controlled diesel fuel injector manufactured to Bosch OEM standards. Its solenoid-actuated design responds to ECU commands to control needle lift, injection timing and fuel delivery. By atomizing diesel into fine droplets, it supports efficient combustion, optimized fuel economy, lower emissions and consistent engine performance. The injector is factory calibrated and designed for direct OE fitment, with multi-stage injection capability, stable injection quantity and an excellent spray pattern.
This injector is intended for Cummins ISBe4, ISBe6.7, ISDe Series, QSB4.5 and QSB6.7 engines, as well as industrial, power generation and construction equipment diesel engines. Appliions include heavy-duty trucks, commercial vehicles, buses, coaches, excavators, wheel loaders, diesel generators, agricultural equipment and industrial power systems. Related Cummins cross-reference numbers include 5263308, 5263314, 3973060, 4892795, 3976372, 4937065 and 4988835. Because numbers can vary by production batch, emission level and engine calibration, buyers should verify injector coding and OE specifiions before ordering.
Wear-resistant internal components and corrosion-resistant construction support long service life in demanding commercial appliions. For reliable operation, clean the fuel system, replace filters, verify the injector seat, apply OEM torque specifiions and complete ECU coding where required. Clean diesel, regular filter replacement and periodic injector balance testing are recommended.
