c-aterpillar Injector N14 Series (Part Number: 3411385) Product Details
The c-aterpillar 3411385 fuel injector is a high-reliability, OEM-matching core component specifically developed for the c-aterpillar N14 series diesel engines, covering N14 Celect electronic, non-Celect mechanical, and STC (Sequential Turbocharging) configurations. It distinguishes itself with three core competitive features: superior anti-dust performance, high-temperature resistance, and efficient fuel atomization—advantages that perfectly align with c-aterpillar’s pursuit of extreme reliability in harsh environments. Crafted with c-aterpillar’s original-grade precision machining technology and reinforced heat-resistant alloy materials, this injector is integrated with a professional dust-proof filter structure, which can effectively isolate 90% of impurities in the air and fuel, avoiding nozzle blockage and internal component wear caused by dust—a key pain point in mining, construction, and other harsh operation scenarios. Its optimized multi-hole nozzle design achieves ultra-fine fuel atomization, ensuring full combustion, reducing fuel consumption by 6-9%, and lowering exhaust emissions while boosting engine power output. Engineered to withstand extreme working conditions, including high temperatures (up to 450℃), high pressure, heavy dust, and chemical corrosion from diesel fuel, it fully inherits c-aterpillar’s "over-standard design" concept, with a structural strength that exceeds industry averages, making it suitable for long-term continuous operation in heavy-duty fields such as mining, construction, long-haul transportation, and industrial power generation. Produced in ISO 9001:2015 and IATF16949 certified facilities, it strictly follows c-aterpillar’s original design specific-ations, undergoes 100% pre-delivery performance testing and dust-proof performance verific-ation, and achieves full compatibility with N14 engine electronic control and fuel supply systems. 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 global after-sales service, consistent with c-aterpillar’s "one sale, global support" service concept. Widely recognized in global markets, it is a trusted premium replacement part for N14 engine maintenance, favored by users in Europe, the Americas, Southeast Asia, and the Middle East for its durability and stability.
