Built for QSK-series service planning, the 4087886 fuel injector assembly is presented for Cummins QSK23 diesel engine applications and related heavy-duty injector groups. Supplier catalogues strongly connect it with 4010025, 4001813, 4087893, 4088427 and 4326780, including NX/PX/RX suffix variants; 4928345, 4001830 and 4010029 form a separate reported group. Because listings are not fully consistent, fitment should be confirmed by engine serial number, CPL, old injector number, photos and exact engine configuration before quotation or shipment.
For QSK23 platforms, the injector supports fuel metering, high-pressure injection, atomization, cylinder balance, return fuel control and combustion protection. The 23-liter inline six-cylinder engine is listed at 760–950 hp / 567–708 kW for well servicing, while QSK23 G-Drive engines use the HPI-PT full-authority electronic fuel system. Cummins states that QSK23 high-pressure injection can reach 29,000 psi, supporting engine response, fuel economy and emissions performance.
Positioned as an industrial-grade component, it offers heavy-duty construction, precision metering, high-pressure compatibility, heat resistance and sealing reliability, with reman supply options, cross-reference support, optional test support and export packaging. Typical equipment categories include mining excavators, generator sets, oilfield power units, construction machinery, crushing and mining power modules, rail or intermodal systems, stationary engines and marine auxiliary power.
