original 20R-0849 Diesel Fuel Injector for 3508 3512 3516 3524 C13 Engine Common Rail Injector Assembly 3920211 392-0211 Construction Machinery original new injector

Engineered for continuous-duty performance across 3500 Series diesel platforms, the 20R-0849 fuel injector delivers precision fuel metering and superior atomization for demanding industrial power applications. This remanufactured OEM replacement is qualified for service in 3408, 3412, 3512, 3512B, 3512C, 3516, 3516B, and 3516C engine families operating in generator sets, marine vessels, mining trucks, oilfield equipment, industrial pumps, compressors, construction machinery, power plants, data centers, and emergency backup power systems deployed across global markets.

Cross-referenced OE numbers 247-9784, 326-1640, 10R-0957, 0R-8477, 0R-8479, and 212-3464 ensure broad compatibility with existing fuel system configurations. The injector executes a five-stage operating cycle—fuel pressurization, metering, atomization, combustion, and power generation—delivering maximum combustion efficiency, improved fuel economy, reduced smoke emissions, stable engine performance, and increased engine longevity under sustained load conditions typical of continuous-duty industrial service.

Proper commissioning requires verification of the injector number and engine serial number, inspection of the injector bore, replacement of sealing components, cleaning of fuel lines, and confirmation of fuel filtration integrity and pressure. Follow specified torque values, use approved installation tools, prevent contamination, and perform calibration when required. Post-installation checks include leak inspection, engine performance monitoring, exhaust verification, and fuel consumption analysis. This assembly resolves hard starting, white smoke, black smoke, power loss, rough idle, high fuel consumption, cylinder misfire, and elevated exhaust temperatures.
