c-ummins Injector N14 Series (Part Number: 4902924) Product Details

The c-ummins 4902924 fuel injector is a high-performance, OEM-compatible electronic unit injector exclusively engineered for the c-ummins N14 14L diesel engine series (1991–2006), boasting broad compatibility with N14-derived QSNT, NT series engines and heavy-duty power systems widely used in industrial, construction, and mining fields. Its core advantages lie in ultra-precise fuel metering, excellent high-pressure stability, and enhanced wear resistance, making it capable of withstanding the extreme operating conditions of heavy-duty equipment—where consistent power output, fuel efficiency, and long service life are non-negotiable. As a fully calibrated, factory-tested finished product, it adheres strictly to c-ummins global manufacturing standards and ISO 9001 certification, integrating advanced piezoelectric actuation technology and precision-machined components to deliver consistent fuel delivery, optimize engine combustion, and reduce exhaust emissions. The injector features a reinforced high-pressure sealing structure and a corrosion-resistant housing crafted from high-strength alloy, effectively preventing fuel leakage and damage from dust, vibration, and extreme temperatures. Designed as a direct-fit replacement part, it requires no mechanical or wiring modifications, enabling quick and efficient installation, while 100% pre-delivery testing ensures reliable performance and extended service life. Backed by a 6-month limited warranty, global delivery (3-7 working days), and professional after-sales support, this brand-new (non-remanufactured) injector is the preferred choice for maintaining peak performance of N14-powered construction machinery, industrial generators, mining trucks, and heavy-duty auxiliary equipment. The OEM Cross-Reference Numbers for 4902924 include 4902924-20, 4384360, 4903319, which are fully interchangeable with the N14 series fuel system and compatible with related engine models, ensuring seamless replacement and perfect compatibility.
