c-aterpillar Injector N14 Series (Part Number: 3411381) Product Details
The c-aterpillar 3411381 fuel injector is a premium, OEM-compatible core component exclusively engineered for the c-aterpillar N14 series diesel engines, covering N14 Celect electronic, non-Celect mechanical, and STC (Sequential Turbocharging) configurations. It stands out in the market with three distinctive core features: enhanced sealing performance, ultra-stable fuel delivery, and low maintenance requirements—advantages that address the pain points of heavy-duty equipment operation, such as fuel leakage, unstable performance, and frequent maintenance. Crafted with advanced precision machining technology and high-strength corrosion-resistant alloy materials, this injector adopts a double-seal structure and optimized valve core design, effectively preventing fuel leakage even under long-term high-pressure operation and harsh working environments. As a normally closed valve, it is controlled by the engine’s ECU (Electronic Control Unit), which sends pulse signals to precisely regulate the opening and closing of the valve needle, ensuring stable fuel delivery and uniform atomization for full combustion. It is engineered to withstand extreme conditions, including high temperatures (up to 420℃), 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, including precision adjustment of valve spring force and valve needle lift to ensure consistent quality and reliable operation. Its key advantages include: double-seal structure for zero leakage, stable fuel delivery for consistent engine power, and wear-resistant components that reduce maintenance frequency and extend service life. 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 high-reliability 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.
