WeiFu 0445110444 Fuel Injector Assembly

The WeiFu 0445110444 is a common rail solenoid-type diesel fuel injector designed for high-pressure direct injection systems. It features a Bosch-based nozzle geometry and solenoid actuator calibrated for Cummins ISB, ISC, ISDe, and ISLe engine platforms ranging from 3.9L to 8.3L displacement. Constructed with hardened alloy steel body and precision-machined control valve assembly, the injector operates at rail pressures up to 1800 bar. The nozzle utilizes a multi-hole spray pattern optimized for combustion efficiency in heavy-duty off-highway applications. Internal filtration screen protects the high-precision mating surfaces from contamination. This assembly serves as a direct replacement for Bosch 0445110444 and cross-references multiple superseded part numbers within the Bosch common rail injector family. It is widely deployed in Chinese construction machinery brands including XCMG, SANY, Liugong, Zoomlion, and Shantui equipped with Dongfeng Cummins power units.
