Bosch 0445110376 Common Rail Injector Assembly

The Bosch 0445110376 is a solenoid-actuated common rail diesel injector designed for high-pressure direct injection systems operating up to 2,500 bar. It utilizes a multi-hole nozzle geometry to ensure precise fuel atomization, optimal spray pattern, and combustion efficiency in 2.8L displacement diesel engines. The injector body is manufactured from high-strength alloy steel to withstand cyclic pressure loads, while the control valve assembly (part number F00VC01383) ensures rapid response times for pilot, main, and post-injection events. Each unit undergoes end-of-line testing on Bosch DCI700 test benches to verify opening pressure, leakage rate, back-leakage flow, and injection quantity across multiple RPM points. The calibration code (IMA/CMA) is laser-etched on the solenoid housing for ECU programming compatibility. The assembly includes a high-pressure connector, copper sealing washer, and retaining clamp groove per OEM specification. Primary applications include the Cummins ISF2.8 (Firefox) and ISF3.8 engine platforms installed in Foton, JAC, Great Wall, and Ford light commercial vehicles, as well as industrial generator sets and mini excavators. Cross-references include Cummins OEM numbers 5258744, 5285744, and 5309291. Installation requires high-pressure fuel line torque adherence and ECU calibration code entry to prevent drivability faults.
