The c-aterpillar 242-0857 fuel injector is a premium, OEM-compatible common rail diesel fuel injector specifically designed for c-aterpillar C9 series diesel engines, with full compatibility with c-aterpillar C7 series engines. It strictly follows c-aterpillar’s original design standards, high-strength alloy steel material requirements, and factory precision calibration parameters, serving as a reliable new aftermarket replacement for C9 engine fuel injection systems. With common part number variations including 2420857 and CA2420857, it perfectly matches all standard configurations of c-aterpillar C9 industrial diesel engines. This injector integrates advanced electromagnetic actuation technology, high-sensitivity electronic control modules, and precision-ground nozzles, featuring stable 24V operating voltage and 1800MPa injection pressure, which ensures real-time and accurate regulation of injection timing, fuel delivery volume, and injection pressure. Its ultra-fine fuel atomization (12-micron particle diameter) achieves complete combustion, effectively enhancing engine power output and fuel efficiency, while avoiding power loss, increased fuel consumption, and engine misfires commonly caused by low-quality aftermarket injectors. Every 242-0857 injector undergoes rigorous precision machining, meticulous assembly, and 100% comprehensive bench testing (including flow balance, spray uniformity, electrical performance, and leakage tests) before shipping, complying with ISO 9001 and CE certific-ations to withstand harsh working environments such as construction sites, mining areas, and industrial operations. Equipped with high-strength alloy steel internal components and anti-corrosion coating, it effectively resists fuel leakage, carbon deposition, mechanical wear, and high-temperature aging, significantly extending the service life of the C9 engine and reducing long-term operation and maintenance costs. Widely applied to c-aterpillar C9-powered heavy construction machinery (including 320D, 323D, 329D excavators), as well as industrial equipment and heavy-duty vehicles equipped with C7/C9 series engines, it offers abundant in-stock availability, batch order discounts (MOQ 1 piece, better discounts for 10+ pieces), 6-month quality warranty, neutral or custom packaging, and fast delivery (3-5 working days for in-stock items), making it suitable for cross-border export to meet the high-quality demands of global customers for C9 engine injectors.
