Engineered for demanding heavy-duty operations, the 7C-9578 diesel fuel injector delivers precise fuel atomization and reliable performance for large-bore industrial engines. Built with premium alloy steel and finished with an anti-corrosion coating, this injector is designed to withstand extreme pressures up to 2,000 bar, making it an ideal solution for marine vessels, stationary power plants, mining fleets, and construction machinery operating under continuous high-load conditions.
This OEM-grade injector directly replaces original number 7C-9578 and is fully cross-referenced with 7C9578, 7C9579, 9N-9352, and 6I-3558 for maximum sourcing flexibility. It is compatible with 3512A, 3512C, 3516B, and 3516C engine platforms covering power outputs from 1,500 kW to 2,800 kW at 1,800–2,200 rpm. The standard flange mount ensures a bolt-on fit with 3512A engines, while precision-machined tolerances guarantee accurate spray patterns that reduce particulate and NOx emissions for cleaner combustion and improved fuel economy.
Installation is straightforward: torque mounting bolts to 35–40 Nm, bleed the fuel system, and verify injector operation prior to full-load service. Recommended inspection intervals of every 500 operating hours help prevent nozzle clogging, power loss, or rough idle. Backed by consistent quality control and versatile compatibility across marine, construction, power generation, mining, and oil & gas sectors, the 7C-9578 injector is a dependable choice for global B2B buyers, distributors, and fleet operators.
