c-aterpillar Nozzle Series (Part Number: 7W7045) Product Details

The c-aterpillar 7W7045 fuel injector nozzle is a high-precision genuine OEM component, specifically engineered for c-aterpillar ultra-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, durability, and emission compliance. 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 heat-resistant alloy steel with advanced anti-corrosion and anti-wear coating, this nozzle features an optimized 8-hole orifice design that achieves ultra-fine fuel atomization, uniform fuel distribution, and complete combustion, effectively enhancing engine power output by 10-12%, reducing fuel consumption by approximately 9.5%, and minimizing harmful exhaust emissions. It boasts exceptional wear resistance, corrosion resistance, and high-temperature stability, capable of adapting to the most extreme operating environments such as large-scale deep mining, heavy-duty construction, long-haul ultra-heavy cargo transportation, and industrial power generation. 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 ultra-heavy-duty equipment maintenance and repair.
