Weifu 0445120477 Common Rail Fuel Injector Assembly

The Weifu 0445120477 is a solenoid-type common rail fuel injector designed for heavy-duty diesel applications. It is manufactured to Bosch 0445120477 specifications and serves as a direct replacement for injectors used in Cummins ISB, ISC, ISDe, and ISD engine platforms equipped with CM2150 electronic control systems. The injector assembly integrates a stainless steel nozzle (reference 0433172099) and a solenoid control valve (reference F00RJ02410), calibrated for high-pressure common rail operation up to 1800 bar. It is engineered for 24V electrical systems standard in commercial vehicle and construction equipment fleets. The component undergoes bench testing for flow rate, leakage, and spray pattern consistency to ensure emissions compliance and combustion efficiency. Primary applications include Dongfeng commercial vehicle platforms such as DaliShen, Jiayun, and Oushang series trucks powered by Dongfeng Cummins engines. Cross-compatibility extends to JAC heavy trucks and various construction machinery platforms including hydraulic excavators, wheel loaders, and bulldozers utilizing the same Cummins engine families.
