The c-aterpillar OR9-539 fuel injector is a genuine OEM replacement component, precision-machined and factory-calibrated specifically for the c-at 3512B 12-cylinder V-type heavy-duty diesel engine. Manufactured in strict accordance with c-aterpillar’s original engineering specific-ations and global quality control standards, this injector is engineered for durable, stable performance in harsh industrial and marine operating environments. It features advanced MEUI (Mechanically Actuated Electronically Controlled Unit Injector) technology to deliver precise fuel metering, consistent injection timing, and ultra-fine fuel atomization, which optimizes combustion efficiency, cuts fuel consumption, and reduces harmful exhaust emissions. Constructed with high-strength forged alloy steel housing and wear-resistant precision internal parts, it resists prolonged high-pressure fuel cycling, diesel corrosion, abrasive contaminants, and extreme temperature swings, guaranteeing reliable engine operation and extended service life. As a critical spare part, the authentic OR9-539 injector restores the 3512B engine’s factory-rated power output, eliminates rough idle and power loss, and minimizes costly unplanned downtime for stationary power generation, marine propulsion, oilfield operations, and heavy industrial machinery applic-ations.

1. Core Basic Specific-ations Table

Parameter Item Specific Value
Part Number OR9-539
Compatible Engine Model c-aterpillar 3512B Series Diesel Engine
Injector Type MEUI (Mechanically Actuated Electronically Controlled Unit Injector)
Rated Injection Pressure 2100–2600 bar (Factory Calibrated)
Material Construction High-Strength Forged Alloy Steel, Anti-Corrosion Seals, Wear-Resistant Internal Components
Operating Temperature Range -40°C to 180°C
Installation Type Direct OEM Replacement, Plug-and-Play
Quality Certific-ation c-aterpillar Original Factory Standard

2. Performance Advantages & Applic-ation Compatibility Table

c-ategory Detailed Description
Core Performance Benefits Delivers ultra-fine fuel atomization with tight injection timing tolerance (±0.5%), ensuring balanced fuel delivery across 12 cylinders and complete combustion. Reduces fuel consumption, suppresses black/white exhaust smoke, stabilizes idle speed, and lowers NOx and particulate emissions to meet industrial and marine environmental requirements. Resists high-pressure fatigue and diesel corrosion for extended durability.
Applic-ation & Compatibility Exclusively compatible with c-at 3512B engine-driven equipment: stationary generator sets, marine main/auxiliary engines, offshore drilling rigs, oilfield pumping systems, and heavy industrial machinery. Ideal for routine maintenance, engine overhauls, and troubleshooting power loss, high fuel consumption, and hard starting issues; direct interchange with original parts, no post-installation calibration needed.
