Bosch 0445111101 Common Rail Injector Assembly

The Bosch 0445111101 is a second-generation common rail injector designed for diesel engine applications. It utilizes electromagnetic solenoid actuation to control the injection event with high precision. The injector body is manufactured from high-strength alloy steel to withstand peak rail pressures of 1800 bar. The nozzle features a multi-hole spray pattern optimized for combustion efficiency and emissions compliance. Internal components include a hardened steel control valve, spring assembly, and precision-machined nozzle needle. The injector incorporates a QR code or data matrix on the solenoid body containing calibration codes (IMA codes) required for ECU programming during installation. This unit serves as a direct replacement for OEM applications specifying the 0445111101 part number. Proper torque specifications for the high-pressure connector and mounting fasteners must be observed during assembly to ensure sealing integrity and prevent fuel leakage.
