The c-aterpillar 20R-5077 fuel injector is a high-performance, OEM-compatible common rail component specifically engineered for c-aterpillar C9.3 series diesel engines, with cross-reference part numbers 20R5077, 460-8213, 4608213, and CA20R5077. As a critical core component of the C9.3 engine’s fuel delivery system, it adopts advanced Common Rail Electronic Control technology, fully complying with c-aterpillar’s original design and performance standards, and is also compatible with c-aterpillar C9 series engines for cross-model applic-ations. This injector is optimized for the C9.3 engine’s 9.3L displacement and 270–390 horsepower output, featuring a 7-hole VCO precision nozzle that delivers ultra-precise fuel metering, accurate injection timing, and superior atomization, with a flow rate of 570±5% cc/min @ 100 bar and a rated pressure of 2000–2400 bar to ensure efficient, stable, and clean combustion. Manufactured in strict accordance with c-aterpillar OEM standard 1N-3668, ISO 9001 and IATF 16949 certific-ation requirements, each unit undergoes 100% factory bench testing, including high-pressure performance verific-ation, spray pattern detection, and strict sealing inspection, ensuring reliable performance and consistent quality for heavy-duty working conditions. It features a high-strength alloy steel body with anti-corrosion coating, enhancing wear resistance and durability to withstand the harsh operating environments of construction, mining, and industrial sites where C9.3-powered equipment is widely used. As a direct OEM replacement part, it enables plug-and-play installation without any modific-ations to the engine or fuel system, effectively resolving common engine issues such as misfires, power loss, excessive fuel consumption, and abnormal emissions caused by injector wear or failure. With a 12-month quality warranty, flexible MOQ (1 piece minimum), neutral export packaging (customizable upon request), and fast global delivery, the 20R-5077 injector is a cost-effective and reliable choice for maintaining peak performance of c-aterpillar C9.3 series engines, widely supplied to global aftermarket markets and compatible with a variety of C9.3-powered heavy equipment.
