Cummins Injector QSK23 Series (Part Number: 4928347) Product Details

The Cummins 4928347 fuel injector is a high-precision OEM-grade common rail component exclusively engineered for the Cummins QSK23 heavy-duty diesel engine, which is widely applied in mining dumpers, crawler cranes, industrial power generation units, and other heavy-duty equipment[superscript:1]. As a core component of the engine’s fuel supply system, this injector integrates advanced electronic control technology and precision manufacturing processes from world-class equipment[superscript:4], boasting core features such as excellent high-pressure resistance (compatible with 2758 kPa pressure valves[superscript:2]), ultra-precise fuel metering, superior durability, and seamless compatibility with QSK23 engine systems. Constructed from high-strength alloy steel and processed by advanced precision CNC machining (including German Heckert and Japanese MAZAK machining centers[superscript:4]) and vacuum degassing technology, the 4928347 injector can withstand extreme working pressures up to 2800 bar, adapting to harsh operating environments such as high-temperature, high-vibration mining sites and construction areas. It adopts a direct bolt-on installation design, requiring no modific-ations to the original engine wiring or pipelines, with the installation torque complying with QSK23 engine specific-ations (88 N•m / 65 ft-lb[superscript:2]), which greatly reduces maintenance time and labor costs. Manufactured in strict accordance with Cummins OEM standards, ISO 9001 quality certific-ation, and relevant industry specific-ations, each 4928347 injector undergoes rigorous pre-delivery testing, including fuel atomization, sealing, and durability tests, to ensure stable performance and reliable quality. The verified OEM Cross-Reference Numbers for 4928347 are 4928347, 4928345, 4928346, 3766446, 4326780, 4088428, ensuring wide interchangeability and convenient replacement for global users. With a product dimension of 30.2cm*12.1cm*7.3cm, it is brand-new and non-remanufactured, supplied directly from the factory with sufficient inventory, fast global delivery, and a 6-month quality warranty, providing cost-effective and reliable support for the efficient operation and maintenance of QSK23 series engine-powered equipment.
