The c-aterpillar 293-4073 fuel injector is a high-performance OEM-compatible component specifically developed for c-aterpillar C9 series diesel engines, with cross-reference part numbers 2934073, CA2934073 and 10R-7223[1]. As a core component of the C9 engine’s fuel injection system, it adopts the advanced HEUI (Hydraulically Actuated Electronically Controlled Unit Injection) technology—an essential design of c-aterpillar C9 fuel delivery systems that integrates hydraulic drive and electronic control to achieve precise fuel metering and timing adjustment. This injector is manufactured in strict compliance with c-aterpillar’s original design standards, ISO 9001 certific-ation requirements, and rigorous quality control processes, serving as a reliable direct replacement for the original C9 engine fuel injection unit and ensuring seamless plug-and-play integration without any modific-ations to the engine or fuel system. As a new aftermarket part sourced from professional manufacturers specializing in diesel fuel injection system components, it is engineered to meet the high-performance and durability demands of C9-powered equipment operating in harsh working environments such as construction sites, mining operations, and industrial generator sets. Equipped with precision-machined multi-hole nozzles that ensure superior fuel atomization (with droplet size as fine as 13 microns), a high-strength heat-treated alloy steel body, and a corrosion-resistant coating, it delivers stable 24V operation, accurate fuel atomization, and consistent injection performance—critical for optimizing engine combustion efficiency, boosting power output, and reducing harmful emissions. Every unit undergoes 100% factory bench testing, including electrical performance, pressure resistance, spray pattern (meeting ISO 4010 standards for spray cone angle deviation within ±2°), and sealing detection, as well as strict quality inspections to ensure long-term reliability. It effectively mitigates common engine issues like misfires, power loss, and excessive fuel consumption caused by poor atomization or injector failure, and boasts excellent wear and corrosion resistance for a long service life under heavy-duty operating conditions. With in-stock availability, flexible MOQ (1 piece for small orders, batch discounts available), 12-month quality warranty, fast global delivery (3-7 working days), and neutral packaging suitable for cross-border export, the 293-4073 injector is widely applicable to various C9-powered heavy equipment, fully meeting the demands of global aftermarket and export customers. It is perfectly matched with C9 engine-powered excavators, loaders, and other construction machinery, providing stable and efficient performance support for equipment operation[1].
