The c-aterpillar 328-2580 fuel injector is a high-performance OEM-compatible component exclusively developed for c-aterpillar C9 series diesel engines, with cross-reference part numbers 3282580, CA3282580 and 10R-7226. As an indispensable core part of the C9 engine’s fuel injection system, it adopts the advanced HEUI (Hydraulically Actuated Electronically Controlled Unit Injection) technology, which is a core design of c-aterpillar C9 fuel delivery systems. This technology integrates hydraulic drive and electronic control to achieve precise fuel metering and timing adjustment, perfectly matching the C9 engine’s 8.8-liter displacement and 250-450 horsepower output performance. Manufactured in strict accordance with c-aterpillar’s original design standards, ISO 9001 certific-ation requirements, and strict quality control procedures, this injector is a reliable direct replacement for the original C9 engine fuel injection unit, ensuring seamless plug-and-play installation without any modific-ations to the engine or fuel system. As a new aftermarket part produced by professional manufacturers specializing in diesel fuel injection components, it is designed to withstand the harsh operating conditions of construction sites, mining operations, industrial generator sets, and other heavy-duty scenarios where C9-powered equipment is widely used. Equipped with precision-machined 8-hole nozzles for excellent fuel atomization (with droplet size as fine as 6μm), a high-strength heat-treated alloy steel body, and a wear-resistant anti-corrosion coating, it provides stable 24V operation, accurate fuel atomization, and consistent injection performance—all of which are crucial for optimizing engine combustion efficiency, enhancing power output, and reducing harmful emissions to meet EU Stage V equivalent emission standards. Each unit undergoes 100% factory bench testing, including electrical performance, pressure resistance (adapting to the C9 engine’s 2400bar injection pressure), spray pattern (meeting ISO 4010 standards with spray cone angle deviation within ±2°), and sealing detection, as well as strict quality inspections to ensure long-term reliable operation. It effectively solves common engine problems such as misfires, power loss, and excessive fuel consumption caused by poor atomization or injector failure, and has excellent wear and corrosion resistance to ensure an extended service life under heavy-duty working conditions. With in-stock availability (up to 360 units in stock), flexible MOQ (1 piece for small orders, batch discounts available), 12-month quality warranty, fast global delivery (3-7 working days, 5 days delivery from Shiyan, Hubei), and neutral packaging suitable for cross-border export, the 328-2580 injector is widely applicable to various C9-powered heavy equipment, fully meeting the needs of global aftermarket and export customers. It is perfectly matched with C9 engine-powered excavators, loaders, industrial generators, and other construction machinery, providing stable and efficient performance support for equipment operation.
