The C9 fuel injector 266-4446 is a high-precision HEUI (Hydraulically actuated Electronic Unit Injector) component engineered specifically for C9 and C9 ACERT diesel engines, including the 3306, 3406, C9 Marine, and C9 Power Generation variants. As an OEM specification injection assembly, it is electronically activated by the engine ECM and delivers injection pressures exceeding 23,000 PSI (1,600 Bar), ensuring optimized fuel atomization, combustion efficiency, and emissions control across a wide range of heavy-duty operating conditions.
Manufactured using hardened high-strength alloy steel, precision-ground valve assemblies, and high-performance nozzle technology, this C9 diesel fuel injector maintains consistent injection performance throughout extended service intervals. Each unit undergoes factory-tested calibration to verify flow rates, spray patterns, and leak-off performance, providing reliable replacement compatibility for OE numbers 236-0962, 235-2888, 217-2570, 188-8739, 10R-7224, 20R-8063, 387-9434, 328-2573, 293-4071, and 267-9734 in construction, mining, marine, and power generation equipment.
Before installation, operators should clean the injector bore, install new sealing washers, lubricate O-rings with clean diesel fuel, and perform injector leak-off testing. To maintain long-term reliability, use ultra-clean diesel fuel, replace fuel filters regularly, avoid water contamination, monitor fuel pressure, inspect return flow rates, and verify ECM calibration parameters. This maintenance protocol ensures the C9 HEUI injector continues to deliver stable performance in excavators, track type tractors, wheel loaders, motor graders, generator sets, and commercial marine vessels.
