Cummins Injector QSK23 Series (Part Number: 4928349) Product Details

The Cummins 4928349 fuel injector is a high-performance OEM-grade common rail component exclusively designed for the Cummins QSK23 heavy-duty diesel engine, a core power unit widely applied in mining machinery, construction equipment, industrial power generation, and marine auxiliary systems[superscript:2]. As a key part of the engine’s fuel supply system, this injector integrates advanced electromagnetic control technology and precision machining craftsmanship, boasting core features including ultra-high pressure resistance, accurate fuel metering, excellent anti-fatigue performance, and reliable long-term operation. Crafted from high-strength corrosion-resistant alloy steel, it undergoes precision CNC machining and vacuum heat treatment, enabling it to withstand extreme working pressures up to 2900 bar and adapt to harsh operating environments such as high temperature, high vibration, and dusty conditions in mining and construction sites[superscript:1]. The plug-and-play design ensures perfect compatibility with the original QSK23 engine interface, requiring no modific-ations to the original pipeline or wiring, while the installation torque strictly adheres to Cummins QSK23 specific-ations (90 N•m / 66 ft-lb), significantly reducing maintenance time and labor costs. Manufactured in strict compliance with Cummins OEM standards, TS16969 quality certific-ation, and ISO 9001 quality management system, each 4928349 injector undergoes 10+ rigorous pre-delivery tests to ensure zero defects and stable performance. Its verified OEM Cross-Reference Numbers are 4928349, 4928350, 4928351, 3766448, 4326783, 4088430, ensuring wide interchangeability and convenient replacement for global users. With a compact structure (dimensions: 30.8cm*12.5cm*7.6cm, gross weight: 2.4KG), it is brand-new and non-remanufactured, supplied directly from the factory with sufficient inventory, fast global delivery, and a 12-month quality warranty, providing cost-effective and reliable support for the efficient operation of QSK23-powered equipment.
