The c-aterpillar 20R-1267 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 applied in stationary power generation, marine propulsion, industrial machinery, oilfield operations, and large infrastructure support scenarios. Manufactured in full compliance with c-aterpillar’s original engineering specific-ations and stringent quality control protocols, this injector adopts advanced MEUI (Mechanically Actuated Electronically Controlled Unit Injector) technology to deliver superior fuel metering accuracy, refined atomization effect, and stable injection timing. With a rugged reinforced structure and wear-resistant internal parts, it endures long-term high-pressure cycling, diesel corrosion, abrasive impurities, and extreme temperature fluctuations, ensuring consistent performance and prolonged service life. Fitting the authentic 20R-1267 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.

1. Core Basic Specific-ations Table

Parameter Item Specific Value
Part Number 20R-1267
Compatible Engine Model c-aterpillar 3512B Series Diesel Engine
Injector Type MEUI (Mechanically Actuated Electronically Controlled Unit Injector)
Rated Injection Pressure 2100-2600 bar (High-Precision Atomization Setup)
