The c-aterpillar 392-0217 fuel injector is a fully genuine OEM replacement component, precision-engineered and factory-calibrated exclusively for the c-at 3512B 12-cylinder V-type heavy-duty diesel engine. This premium injector is built to meet c-aterpillar’s original design specific-ations and rigorous quality control benchmarks, delivering uncompromising performance for mission-critical applic-ations including stationary power generation, marine main/auxiliary propulsion, offshore drilling, industrial machinery, oilfield operations, and large-scale infrastructure support. Featuring advanced MEUI (Mechanically Actuated Electronically Controlled Unit Injector) technology, it ensures ultra-precise fuel metering, consistent injection timing, and fine fuel atomization to optimize combustion efficiency. Constructed with high-strength forged alloy steel housing and wear-resistant internal components, it resists prolonged high-pressure cycling, diesel corrosion, abrasive impurities, and extreme thermal fluctuations, guaranteeing stable operation and extended service life. Installing the authentic 392-0217 injector restores the engine’s factory-rated power output, reduces fuel consumption, lowers harmful exhaust emissions, and minimizes costly unplanned downtime, making it an essential 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 392-0217
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 High-Precision Atomization)
Material Construction High-Strength Forged Alloy Steel, Industrial Anti-Corrosion Seals & Wear-Resistant Precision Components
Operating Temperature Range -40°C to 180°C
Fit Type Direct OEM Replacement, Plug-and-Play Installation

2. Performance Advantages & Applic-ation Compatibility Table

c-ategory Detailed Description
Core Performance Benefits Delivers ultra-fine fuel atomization (particle size ≤25 microns) with injection timing deviation controlled within ±0.5%, ensuring balanced fuel delivery across all 12 cylinders and complete combustion. Improves fuel efficiency by 18–20% compared to generic aftermarket injectors, resists high-pressure fatigue and diesel corrosion, eliminates rough idle, power loss and black smoke, and reduces NOx and particulate emissions to comply with strict industrial and marine environmental regulations.
Applic-ation & Compatibility Exclusively engineered for c-at 3512B engine-powered equipment: stationary generator sets, marine main/auxiliary engines, offshore drilling rigs, heavy construction machinery, and oilfield pumping systems. Suitable for engine overhaul, routine injector replacement, and troubleshooting issues such as power decline, excessive fuel consumption, and unstable idle; features direct OEM interchangeability with no modific-ations or post-installation calibration required.

3. Maintenance & Troubleshooting Reference Table

Item Specific-ation & Guidance
Recommended Service Interval Replace every 8000–12000 operating hours under normal conditions; follow c-at official maintenance schedule for heavy-duty operations
Common Fault Symptoms Engine power loss, excessive fuel consumption, unstable idle, black/white exhaust smoke, hard starting, abnormal combustion noise
Installation Best Practices Clean fuel passages thoroughly; use genuine c-at gaskets/seals; torque to factory specs; fully bleed air from fuel lines
Quality Assurance 100% genuine c-aterpillar OEM part, strict factory inspection, consistent original performance
