Cummins original For Cummins QSK45 QSK60 diesel Engine Fuel Injector 4001813, Replacement for OEM 3766446, Cross Reference 891801, 4088428, suitable for 8000 Hours operation original new injector

For high-horsepower diesel operations, Cummins fuel injector 4001813 provides a heavy-duty injector assembly option for QSK-series engine sourcing, with QSK60 as the primary application. It is designed to support accurate fuel metering, stable atomization, controlled injection timing, improved combustion stability, balanced cylinder performance, and reliable operation in severe-duty industrial environments. These functions make it relevant to maintenance and parts procurement for mining, marine, generator set, rail, oil and gas, and industrial power applications.

The QSK60 is officially specified by Cummins as a Vee 16-cylinder, 60 L engine covering 2000–2700 hp (1491–2013 kW), with HPI and MCR fuel system options. Cummins describes its QSK60 Modular Common Rail system as electronically controlling injection pressure and timing, while an integrated accumulator in each injector helps reduce pressure pulsation and improve stability. Public catalog data also associates 4001813 with QSK23 and QSK45 searches, but these applications should not be promised without verification.

Use 4001813 as the main OE and SKU reference. Common public cross references include 4088428, 4326781, 4088427, 4087893, 4087894, 4002145, 4326780, and 705513AT, supporting broader replacement-part searches. Because fuel system configuration and ECM calibration can vary, final fitment must be confirmed before shipment using the Engine Serial Number, CPL, old injector label or number, ECM code, fuel system type, and equipment model. This verification-focused approach helps buyers align the injector with the correct engine configuration.
