Application Type |
Heavy Duty Industrial Diesel Injector |
Engineered around the demanding duty cycle of the Cummins QSK19, the Y431K05420 fuel injector is built to match the injection requirements of this inline 6-cylinder, 19-liter diesel engine. It is compatible with the Modular Common Rail Fuel System (MCRS), high-pressure fuel pump technology, and integrated electronic control, making it a precise fit for QSK19, QSK19 G-Drive, QSK19 MCRS, QSK19 Tier 3, and QSK19G configurations, including QSK19 G-Drive ratings of 500–550 kW prime and 550–600 kW standby.
Extensive OE cross-reference coverage simplifies sourcing across global service networks. The injector references Y431K05420, Bosch F00BL0J019, F00BL0J020, 0986435612, and Cummins 4964170 and 4955524 with their NX, PX, RX and KX variants, supporting confident identification by part number, OE number, and engine model. Accurate fuel metering and fine atomization deliver dependable combustion performance across industrial duty cycles in mining, power generation, marine, rail, oil and gas, construction, forestry, and agricultural machinery.
To protect injector service life, focus maintenance on clean diesel fuel, scheduled fuel-filter replacement, regular water separation, and high-pressure system inspection. Dirty fuel, water contamination, poor filtration, metal debris, and incorrect installation are common causes of early failure, often signaled by hard starting, rough idle, black or white smoke, misfire, power loss, and high fuel consumption. Diagnostic monitoring, sealed storage, and careful handling preserve reliability.
