Application Type

Heavy Duty Diesel Engine Fuel Injection Component

Engineered specifically around the Cummins QSK15 engine family, injector 4088725 delivers a direct-fit fuel injection solution for QSK15, QSKX15, QSX15, ISX15, and X15 diesel platforms. The QSX15 is documented as a commercial and industrial generator platform with 14.9 L displacement, inline 6-cylinder configuration, 24V starting system, and Full Authority Electronic Cummins HPI-TP fuel system, with 60 Hz standby ratings up to 500 kW / 625 kVA depending on configuration.

This injector supports precision fuel metering, high-pressure injection capability, and stable atomization, while its heavy-duty construction, high temperature resistance, and reliable sealing sustain long service intervals. Electronic control compatibility helps restore engine power, support fuel economy, and lower misfire risk under load. Cross-number searchability links references such as 4088665, 4062569, 3087560, 570016, 4928260, 1521978, and 4954888 for fast identification across generator, mining, construction, oil and gas, marine auxiliary, railway, and heavy truck applications.

As an export-friendly, repair-shop-friendly component with B2B catalog-ready product data, 4088725 suits engine rebuilding, fleet maintenance, rental service, and emergency power systems. Final fitment must be verified by engine serial number, CPL, old injector number, injector body marking, fuel system type, ECM calibration, and equipment model to ensure correct application.
