Built for demanding industrial diesel power, the Y431K05558 is a heavy-duty fuel injector assembly for Cummins QSK19 engine applications. It receives high-pressure diesel, opens under ECM control, atomizes fuel through precision nozzle holes, and returns excess fuel through the return circuit. This controlled delivery supports stable combustion; on correctly matched QSK19 platforms using the Modular Common Rail Fuel System, precise injection control also helps support lower noise, vibration and smoke, together with optimized fuel economy.
Key B2B selling points include precision fuel metering, fine atomization, stable injection response, industrial durability and high-pressure fuel system compatibility when correctly matched. Application coverage extends across mining trucks and equipment, generator sets, marine power units, oilfield machinery, rail power units, construction machinery, industrial compressors, pump sets, quarry equipment and crushing plants. Export-ready packaging further supports industrial supply and distribution requirements.
Before purchase, verify the old injector number, engine serial number, CPL number, engine model and fuel system version rather than assuming universal interchangeability. Cross references include Y431K05417, Y431KO5417, 4964170, 4964171, 2867149, 4955524, 4918073 and Y431K05248. For dependable service, maintain clean diesel fuel, replace filters on time, drain the water separator, inspect injector wiring, and use return-flow testing and diagnostic-code checks when symptoms appear. Store injectors in sealed, dry, dust-free packaging.
