Bosch original High Pressure Common Rail Diesel Injector, for heavy duty diesel engine application, Engine Injection Valves, Spray Valves, Replacement for OEM, 0445120328 original new injector

Built for demanding diesel fuel systems, the BOSCH 0445120328 (0 445 120 328) is a new original common rail fuel injector, trade number CRIN1-14, manufactured to Bosch OE specifiions. Designed for Common Rail Direct Injection (CRDI), it supports injection pressures up to 2,200 bar and provides accurate fuel metering through ECU-controlled solenoid operation. Documented engine coverage includes Cummins QSB6.7, ISB6.7 and B6.7, plus Komatsu SAA6D107E and SAA6D107E-1, supporting a range of industrial common rail engine appliions.

Bosch micron-level machining and a multi-hole nozzle design support precise fuel atomization, while the heat-treated alloy steel body and nozzle assembly are designed for extended service life. By delivering finely atomized fuel, the injector helps optimize combustion efficiency, power output and fuel consumption while supporting reduced emissions. Depending on engine calibration, it supports Euro III, Euro IV and Euro V diesel emission standards. Cross references include Cummins 5273750, 5273750NX, 5273750PX and 5273750RX, plus Komatsu 5273750, assisting procurement and replacement identifiion.

Documented equipment appliions include Komatsu PC200, PC210, PC220, WA320 and WA380 machines, Cummins generator sets, agricultural machinery, construction equipment and industrial power systems. For installation, replace the sealing washers, clean the injector seat, perform coding where required, verify fuel pressure and conduct return flow testing. A 12-month warranty supports purchasing confidence for heavy-duty diesel maintenance and replacement programs.
