Details
The c-aterpillar 254-4340 fuel injector is a high-performance, OEM-standard common rail diesel injector engineered exclusively for c-aterpillar C9 series engines, with cross-reference part numbers 2544340 and CA2544340. Built to c-aterpillar’s original design and calibration standards, it serves as a direct, plug-and-play replacement for C9 engine fuel systems, ensuring seamless integration without modific-ations. Featuring advanced electronic control, precision multi-hole nozzles, and a robust heat-treated alloy steel construction with anti-corrosion coating, this injector delivers stable 24V operation and high-pressure fuel delivery (up to 2200 bar) for precise injection timing and optimal fuel atomization. Every unit undergoes 100% factory bench testing for pressure, spray pattern, flow balance, and sealing performance, complying with ISO 9001 quality standards to guarantee reliability in harsh construction, mining, and industrial environments. It effectively enhances engine power output, improves fuel efficiency by promoting complete combustion, reduces harmful emissions, and minimizes issues like misfires, power loss, and excessive fuel consumption. With a long service life (≥1,000,000 injection cycles) and resistance to wear, high temperatures, and corrosion, the 254-4340 injector is ideal for heavy-duty c-aterpillar equipment, offering in-stock availability, a 6–12 month warranty, and fast delivery for global aftermarket and export demands.
