The 20R-8069 fuel injector is specifically engineered for the C9 and C9 ACERT engine platform, delivering precise fuel metering and reliable performance across a wide range of heavy-duty applications. As an Electronic Unit Injector (EUI), it operates within an ECM-controlled fuel system that manages a 6-stage injection process — fuel supply, electronic control, high-pressure generation, atomization, combustion optimization, and emission reduction. This ensures stable idle operation, improved cold start performance, enhanced power output, and lower exhaust emissions. The injector is a direct-fit replacement for OE 20R-8069, with cross references including 0R-8069, 10R-7672, 10R-8070, 239-1048, 236-0962, 254-4339, 387-9433, 328-2575, 293-4072, and 293-4069, making it compatible with both OEM replacement and remanufactured engine programs.

Manufactured to OEM equivalent precision standards, the 20R-8069 incorporates heat-treated internal components, a precision-ground nozzle, corrosion-resistant steel body, wear-resistant surfaces, and a high-strength spring system. OEM grade sealing components ensure leak-free operation under high-pressure common rail conditions. With high-pressure fuel delivery and superior fuel atomization, this injector contributes to reduced fuel consumption and increased engine efficiency, while supporting an extended service life of typically 8,000–15,000 operating hours under proper maintenance. Available as OEM, OEM Reman, and high-quality aftermarket versions, it provides flexible sourcing options for distributors, fleet operators, and service shops.

Designed for construction, mining, generator sets, marine, and industrial power unit applications, the 20R-8069 fits -powered equipment including 330D, 336D, 336DL, and 345D wheel loaders, as well as excavators, dozers, and oilfield machinery. Pre-installation requires verification of the injector part number and engine serial number, cleaning of the injector bore, replacement of sealing washers, and inspection of fuel lines and harness connections. During installation, technicians should clean the cylinder head injector seat, apply OEM torque specifications, connect the electrical connector, bleed the fuel system, and perform ECM calibration or injector coding where required. Following maintenance schedules, using high-quality diesel fuel, and replacing filters regularly will help maximize injector service life and maintain long-term engine reliability.
