Engineered specifically for the Perkins C9 and C9 ACERT engine platforms, the OEM Fuel Injector 10R-47641 delivers precision fuel metering through an electronically controlled unit injector system. The injector operates via a 7-stage cycle governed by the engine control module, supplying exact fuel quantities to each combustion event. This precise metering capability directly supports increased engine efficiency, improved fuel economy, and reduced exhaust emissions across demanding operating conditions.

The injector assembly is built with hardened alloy steel internal components, precision-ground moving parts, and a corrosion-resistant surface treatment, enabling reliable operation under high pressure common rail conditions. An advanced multi-hole nozzle design produces an optimized spray pattern with uniform fuel distribution, supporting complete atomization for cleaner combustion. Expected service life ranges from 8,000 to 15,000 operating hours when paired with ultra-clean diesel fuel and properly maintained fuel filtration.

The 10R-47641 injector is compatible with a wide range of Perkins-powered equipment, including 320D through 336D excavators, 966H through 980H wheel loaders, and D7R through D8T dozers, alongside generator sets, mining machinery, and oilfield equipment. Cross-referenced with part numbers 326-1646 and 326-1647, this OEM-specification component is suitable for construction, mining, oil and gas, agriculture, marine, and power generation applications. Proper installation requires verification of part number and engine serial number, clean injector bore preparation, and ECM synchronization following injector trim coding.
