The c-aterpillar 20R-3483 fuel injector is a fully genuine OEM replacement part, precision-machined and factory-calibrated specifically for the c-aterpillar 3512B series 12-cylinder V-type diesel engine. This heavy-duty injector is engineered to excel in harsh operating environments, featuring cutting-edge MEUI (Mechanically Actuated Electronically Controlled Unit Injector) technology that delivers unparalleled fuel metering precision, uniform atomization, and consistent injection timing. Constructed with high-strength forged alloy steel and wear-resistant internal components, it resists prolonged high-pressure fuel cycling, diesel corrosion, abrasive contaminants, and extreme temperature swings, guaranteeing stable performance and extended service life. By installing the authentic 20R-3483 injector, users can restore the 3512B engine’s factory-rated power output, optimize combustion efficiency, reduce harmful exhaust emissions, and minimize costly equipment downtime, making it a critical spare part for routine maintenance, engine overhauls, and fault troubleshooting across industrial, marine, and power generation applic-ations.

2. Performance Advantages & Applic-ation Scope Table

c-ategory Detailed Description
Core Performance Advantages Delivers ultra-fine fuel atomization (particle size ≤25 microns) for complete combustion; controls injection timing deviation within ±0.5% to ensure balanced fuel delivery across all 12 cylinders; improves fuel efficiency by 18–20% compared to generic aftermarket injectors, lowering long-term operating costs; eliminates rough idle, power loss, cylinder misfires and black smoke emissions; reduces NOx and particulate matter to meet strict industrial and marine environmental regulations; enhances corrosion and wear resistance for extended service intervals.
Applic-ation & Compatibility Designed exclusively for c-at 3512B engine-powered equipment: stationary generator sets (industrial plants, mines, data centers), marine main/auxiliary propulsion engines, offshore drilling rigs, heavy construction machinery, and oilfield pumping units; suitable for engine overhaul, routine injector replacement, and troubleshooting issues like power decline, excessive fuel consumption and unstable idle; direct interchange with OEM fuel system components, no modific-ation or professional re-calibration required for installation.
