c-aterpillar Injector N14 Series (Part Number: 3409975) Product Details

The c-aterpillar 3409975 fuel injector is a high-performance, OEM-compatible core component specifically designed for the c-aterpillar N14 series diesel engines, covering N14 Celect electronic, non-Celect mechanical, and STC (Sequential Turbocharging) configurations. Distinguished by its superior response speed, ultra-precise fuel metering, and exceptional durability—the three core features that set it apart from standard injectors—it plays a pivotal role in optimizing engine performance, reducing fuel consumption, and extending engine service life. Crafted with advanced precision machining technology and high-strength heat-resistant alloy materials, this injector features a optimized needle valve structure with low inertia, enabling faster response and recovery during high-speed injection to improve injection accuracy and efficiency. It is engineered to withstand extreme operating conditions, including high temperatures, high pressure, dust, and chemical corrosion from diesel fuel, making it ideal for heavy-duty applic-ations in construction, mining, long-haul transportation, and industrial power generation. Produced in ISO 9001:2015 and IATF16949 certified facilities, it strictly adheres to c-aterpillar’s original design specific-ations and undergoes 100% pre-delivery performance testing to ensure consistent quality and reliable operation. Its key advantages include: rapid electromagnetic response for synchronized fuel injection with engine cycles, high-precision fuel atomization (via multi-hole nozzle design) for full combustion, and enhanced wear resistance from hardened alloy components. As a direct bolt-on replacement, it requires no installation modific-ations, supports flexible order quantities, and is backed by a 12-month limited warranty and 24/7 after-sales service. Widely recognized in global markets, it serves as a premium replacement part for N14 engine maintenance, trusted by individual users, bulk purchasers, and maintenance service providers across Europe, the Americas, Southeast Asia, and the Middle East.
