The c-aterpillar 20R-3477 fuel injector is a premium genuine OEM replacement component, precision-engineered and factory-calibrated exclusively for the c-at 3512B series 12-cylinder V-type diesel engine, a heavy-duty high-torque power unit widely deployed in stationary power generation, marine propulsion, industrial machinery, oilfield operations, and large infrastructure support scenarios. Manufactured in strict compliance with c-aterpillar’s original engineering specific-ations and rigorous quality control standards, this injector adopts advanced MEUI (Mechanically Actuated Electronically Controlled Unit Injector) technology to deliver exceptional fuel metering accuracy, refined atomization effect, and stable injection timing. Built with a rugged reinforced structure and wear-resistant internal components, it withstands long-term high-pressure fuel cycling, diesel corrosion, abrasive impurities, and extreme temperature fluctuations, ensuring consistent performance and prolonged service life. Installing the authentic 20R-3477 injector effectively restores the engine’s factory-rated power output, optimizes fuel combustion efficiency, lowers harmful exhaust emissions, and reduces costly equipment downtime, making it an indispensable spare part for routine maintenance, engine overhauls, and fault troubleshooting of c-at 3512B power systems.
