The c-aterpillar 169-7408 fuel injector is a premium, OEM-matched common rail component exclusively engineered for c-aterpillar C9.3 series diesel engines, with cross-reference part numbers 1697408, 169-7408, 232-1168, 156-3895, and 204-2467. As a vital core part of the C9.3 engine’s fuel delivery system, it integrates advanced Common Rail Direct Injection (CRDI) technology, fully adhering to c-aterpillar’s original design standards and performance parameters, while also maintaining broad compatibility with c-aterpillar 3126B series engines and 3116 series engines (engine code 6830 SE) for expanded applic-ation scenarios. Optimized for the C9.3 engine’s 9.3L displacement and 270–390 horsepower output, this injector is equipped with a precision-machined 6-hole SAC nozzle (0.015 inch hole size) with a 160° spray pattern, delivering ultra-accurate fuel metering, precise injection timing, and excellent atomization effect—itsWith a rated pressure of 2200–2600 bar, it ensures efficient, stable, and clean combustion, effectively reducing fuel consumption by 4–6% compared to conventional injectors and minimizing harmful emissions (CO reduced by 32%, HC reduced by 48%) to meet EU Stage V, EPA Tier 4 Final, and global environmental standards. Manufactured in strict compliance with c-aterpillar OEM standards, ISO 9001 certific-ation requirements, each unit undergoes 100% professional factory bench testing, including high-pressure performance verific-ation, spray pattern detection, and strict sealing inspection, ensuring reliable performance and consistent quality even in the harshest heavy-duty working conditions. It features a high-strength high-speed steel body with vacuum quenching heat treatment (hardness HRC63-66), significantly enhancing wear resistance and service life, which can perfectly match the C9.3 engine’s overhaul cycle and adapt to harsh operating environments such as construction sites, mining areas, industrial workshops, and marine vessels. As a direct OEM replacement part, it supports plug-and-play installation without any modific-ations to the engine or fuel system, effectively solving common engine problems such as misfires, power loss, excessive fuel consumption, and abnormal emissions caused by injector wear, aging or failure. Available as a new aftermarket part with a 12-month quality warranty, flexible MOQ (1 piece minimum, negotiable), neutral or original export packaging (customizable according to customer requirements), and fast global logistics delivery (2-7 working days), the 169-7408 injector is a cost-effective and reliable choice for maintaining the peak performance of c-aterpillar C9.3 series engines, widely supplied to global aftermarket markets including North America, South America, Western Europe, and Southeast Asia, and compatible with a variety of C9.3-powered heavy equipment. Its optimized solenoid control ensures fast response (millisecond level), enabling multiple injections to further optimize combustion process, reduce noise, and lower emissions, while its stable performance ensures minimal downtime for equipment operationsuperscript:2superscript:5.
