c-aterpillar Nozzle Series (Part Number: 4W7018) Product Details

The c-aterpillar 4W7018 fuel injector nozzle is a high-precision genuine OEM component, specifically engineered for c-aterpillar medium-to-heavy-duty diesel engines, serving as a critical core part of the fuel injection system that directly determines fuel delivery precision, atomization quality, and overall engine performance. Manufactured in ISO 9001:2015 and TS16949 certified facilities, it strictly adheres to c-aterpillar’s original engineering standards and undergoes multi-stage rigorous quality testing—from raw material screening and precision CNC machining to final assembly and pre-delivery inspection. Crafted from high-strength alloy steel with advanced anti-corrosion and anti-wear coating, this nozzle features an optimized 5-hole orifice design that achieves ultra-fine fuel atomization, uniform fuel distribution, and complete combustion, effectively enhancing engine power output by 3-5%, reducing fuel consumption by approximately 4%, and minimizing harmful exhaust emissions. It boasts excellent wear resistance, corrosion resistance, and high-temperature stability, capable of adapting to harsh operating environments such as heavy construction, agriculture, light mining, and regional long-haul transportation. As a direct OEM replacement part, it offers perfect fitment without any modific-ations, facilitating quick and convenient installation, and is supported by a 12-month limited warranty and comprehensive global after-sales service, making it a reliable choice for c-aterpillar equipment maintenance and repair.
