Bosch 0445110440 Diesel Fuel Injector Assembly

The Bosch 0445110440 is a solenoid-type common rail diesel injector designed for high-pressure direct injection systems. It features a compact nozzle geometry optimized for fuel atomization and emission control. The injector operates at system pressures up to 1800 bar and is calibrated for specific engine control unit (ECU) mapping. This unit serves as a direct replacement for OEM part numbers in various light commercial vehicle applications. Technical data includes solenoid actuation, multi-hole nozzle configuration, and hardened needle valve assembly for durability under high cycle fatigue. Cross-reference interchangeability should be verified against specific engine control unit software versions and calibration codes (IMA/C2I) printed on the injector head. Installation requires new high-pressure fuel lines and copper sealing washers to ensure leak-free sealing at combustion chamber pressures.
